Wotja Past

See SSEYO Koan (used by Brian Eno 1995 when he coined the term 'generative music'), Noatikl, Mixtikl, Liptikl, Tiklbox and retired Wotja versions.

What's New in W22

Wotja evolves every year, and Wotja 22 is no exception!

  • MAJOR NEW FEATURE: Plug-in Hosting
    • The Wotja App (but not Wotja Plug-in) now supports hosting of 3rd party Instrument/Synth & FX Plug-ins (for a selection of favorites to try out, see our Fan-Favorite Plug-ins page)
    • This means Wotja is now a generative music DAW - with both free ("Wotja 22") and paid-for ("Wotja 22 Pro") variants
      • If you search the App Store (iOS or macOS) for "free audio unit host" or "free auv3 host" then at the time of writing there are no results returned for general purpose hosts (meaning one that can use any 3rd party plug-in).
      • "Wotja 22" might be the first FREE general purpose Audio Unit Host on the App Store when released (1st Jan 2022)!
      • The free version operates by default in 'Lite' mode, so it does have some limitations, but it is powerful nonetheless.
    • The versions for iOS/macOS support hosting of AU3 [AKA AUv3] Plug-ins
    • The versions for Windows support hosting of VST3 Plug-ins
    • Plug-in Hosting is accessed via a new "Plug-ins" tab in Mix mode
    • Wotja mixes still work even without using Hosted Plug-ins and Plug-in Hosting information is saved to the mix file when it is saved (and those mixes can also be used in Boxes/Albums)
    • There are 6 "Plug-in Chains" each comprising an instrument selector (for either Wotja Output or a plug-in Instrument), 3 "FX slots" and an output level slider plus one Master FX with 4 "FX slots" and final slider
    • Multiple independent Wotja track filtering can be used when the instrument is Wotja Output
    • Powerful MIDI Channel filtering can be deployed on the Wotja MIDI routed to an instrument plug-in
    • Plug-in scanning "just works"
    • Plug-in UIs can be displayed in the Hosting window area (default Apple) or in pop-up windows (default Windows)
  • MAJOR NEW FEATURE: VST3 Plug-in for Windows
    • A Wotja VST3 Plug-in is included in Wotja 22 for Windows
  • NEW FEATURE (iOS/macOS/Windows): Plug-in Scanner screen for keeping track of Plug-in scanning
    • Plug-ins are sorted on "Manufacturer, Name".
    • Plug-ins that fail validation are shown at the bottom of the list, in red, in "Failed Validation" section.
    • Action Menu items: "Rescan Plug-ins"; "Reset Failed Plug-ins list, and Re-scan"; "Export list of failed Plug-ins to Clipboard".
    • Plug-in icons, where available, are shown in Plug-ins and Plug-in browser screens.
  • MAJOR NEW FEATURE: Generator Type "Sequence" with sub-type "Euclidian"
    • What were called "Pattern" and "Text to Music" (TTM) Generators are now Generator sub-types in a new "Sequence" Generator
    • This change was made to allow us to add a new "Euclidian" Generator sub-type (below) and also to add powerful new properties to the TTM Generator sub-type: "After Tune Repeats", "Rhythm Strategy" and "Duration Multiplier"
    • Sequence Generators support an Array of Items ("Sequence Array" and "Sequence Array Items")
    • Each Item (and there can be several) comprises the data required by the Generator sub-type for it to generate when active; Items can themselves be sequenced or selected at random
    • The color of the Sequence Generator is that of the active Item (i.e. Generator sub-type)
    • Mix Generator networks will still look largely the same as before as "Pattern B" and "TTM" colors have remained the same, but the less used "Pattern R" and "Pattern F" have a different color; Euclidian has a new color of course!
    • Unlike other Sequence Generator sub-types, Euclidians don't auto-pad out to the end of the bar
      • Euclidians have 'classic' Euclidean properties but we've also added "Range" settings to make them more interesting
      • Euclidian properties include: "Steps", "Steps Range", "Fills", "Fills Range", "Rotation", "Rotation Range", "Repeats", "Repeats Range", "Pitch", "Pitch Range", "Duration", "Rhythm Strategy" and "Pitch Strategy"
  • MAJOR NEW FEATURE: Wotja App Extensions for iOS and macOS Safari
    • The Wotja App Extension for Safari allows the Wotja App to play the WJURL when a webpage that includes a WJURL is loaded by Safari.
    • Wotja files can be embedded in a web page as a Wotja URL ("WJURL") - try some examples!
    • For this to work you must have the Wotja App running in the background and Wotja App Extension enabled with appropriate website permissions
    • A WJURL includes Plug-in Hosting information, meaning the WJURL can play the same for someone who already has those same plug-ins installed on their device - exciting!!
  • BRAND NEW CONTENT: New SF2 & Templates
    • SF2: "IM Brush Kit", "IM Hand Percy" & "IM World Instruments"
    • SF2: Additions to "IM Synth" & "IM Drums"
    • Templates: "BP22 Drums" & "BP22 Drums Ambient" Drum Template Paks; these use the new Euclidian Generator sub-type & new SF2
    • Templates: "Mixed 1" Template Pak that used the new "IM World Instruments" SF2
  • NEW FEATURE: Context sensitive In-app Help
    • Includes the full & highly inter-linked "Wotja User Guide".
    • A "Help Resources" page with some handy information to help you get started with Wotja.
    • Settings > General > "Help: In-App (uncheck for Online Help)" toggle allows you instead to view online versions of the two above files.

    • Generator Types Pak: Better naming and wider selection of Pak items
    • "V22 Play me!": This included Wotja mix file uses some of the new Templates!
    • Intermorphic Music/Sounds/Text/Script engines are now renamed to be Wotja Engines (i.e. IME > WME; ISE > WAE; ITE > WTE; IWS > WSE)
    • macOS: hosted AUv2 plug-ins must be signed and marked as 'sandboxSafe' or they are ignored by Wotja
    • Added support for Windows 11

User Reviews

"Superlative Generative Music App"

"I enjoy Wotja more and more with each new version and Wotja 22 Pro is sure to be a hit with every user. Now with the ability to use VST3 plug-ins within the app, its useability has increased immensely. Further to this, the app itself can be used as a VST3 plug-in within your DAW. Amazing work, guys, and the Pro version is worth 10 times as much as the cost price! Thank you!

"Great! Amazing! Love it! "

" I've looked at quite a few music generators. There are some inexpensive ones, some good ones, and even a few great ones, but none were good (much less great) AND inexpensive until I found Wotja! Wow!!! This thing is solid, and it's many years of development shows in every respect. Plus, it generates astonishingly good output at any level of control you desire. Get it! You won't be disappointed. :-D"  Thank you!

"Total game changer"

"I’ve been using Wotja Pro 21 for just under a year and thought that it was the absolute best generative sequencer available. I stand corrected. The UI changes and tweaks are nice in Wotja Pro 22, and the new euclidian sequencer is great, but what really sets this app apart from earlier versions, and anything else out there at the moment is the ability to use all your existing AUV3 plug-ins on tracks in here. The existing music engine is already pretty good, but this is a game changer! Fantastic work by the developers. Kudos to the team!"  Thank you!

"Amazing tool for ambient music at a crazy good price!"

"Wotja is so inspiring! It opened a whole new door in creating music! Intuitive enough to get going quickly, but immersive and powerful enough to really dig your teeth in!"  Thank you!

"Must Have Generative App"

"If you are at all interested in generative music then Wotja is a must buy. Version 22 takes things a notch higher with both standalone and plugin versions included. This means that your compositions can make use of all of your virtual instruments either inside your DAW or in the standalone app. That said, the built-in WAE sounds are excellent and provide a good match for the in-app music generators. Intermorphic are a small company who seem to work tirelessly to improve the app and document its use on their website. This is probably the most complex generative app around, and while I haven't yet delved into the deeper complexities, I have made some beautiful compositions using combinations of the many included templates. So you can get great results without delving too deep if you don't want to, but will no doubt be rewarded if you do. Highly recommended!"  Thank you!

"fantastic, inspiring"

"this has got me immediately out of a creative block. very deep and lots to get into. the manual is difficult but i understand as the author says that this stuff is harder to explain than just to dig into and learn on the job. find of the year so far. Thank you!


"This app is mindblowing! A massive set of features and very good support. Well done guys!! "  Thank you!


"I have found nothing better for beautiful, sublime generative music. This app is a lot deeper than at first glance, and it is worth taking the time to learn more to get even more from it. "  Thank you!

"Beautiful and Deep…."

"I hadn’t heard of Wotja before, but I certainly won’t forget it. This app is just wonderful in so many ways. If you want to press a few buttons to create a gorgeous ambient playlist to soothe you to sleep, this will do it - but not just by playing pre-recorded music…. It does it by making generative music that plays to the rules you can set. Want to dig deeper? This thing is deep as the sea…. You can tinker with just about every aspect of music creation. The interface is very streamlined and you will soon find yourself immersed in a wonderful musical world with a life of it’s own! For serious musos, this app will talk to your DAW, meaning you can use it’s generative note creation routines to play your own virtual instruments. One of the devs is active on forums and, apart from being there to explain aspects of the software to noobs like me, he also takes suggestions for future updates very seriously. I’ve been using Wotja for 5 days now and find myself in a very relaxed, zen-like state of awe of this masterpiece. Best twenty something pounds I spent in a very long time!."  Thank you!

"Still growing and still amazing software"

"I’ve use Wotja and its earlier incarnations of Noatikl/Mixtikl since I have had my first iPad. There really is nothing quite like it for composing music. Whether its generative ambient soundscapes, classical compositions, modal Jazz or you name it, this is a great tool to get things fleshed out. The interface is fairly spartan and the learning curve is steep but well worth it. In earlier versions, my advice was always, get used to the MIDI routing, turn off the sounds and drive other instruments with it (which still works) but now with AUv3 hosting, you can finally do all of your composing and instrument arrangement within Wotja. Why is that so important? If you’ve tried combining MIDI, AUs and concurrently running apps on iOS you probably know how crash prone all of that can be. Even with state of the art iPads with M1 chips, the software just isn’t as bullet-proof as desktops provide. The ability to use all of Wotja’s features with your favorite synths hosted by just Wotja is really a game-changer. The developers are very active on the product and despite some stability jitters, Wotja is really becoming a full-featured composition tool."  Thank you!

"Top-down approach to generative music"

"Wotja is an out-of-the-box player of nice ambient generative music, but also offers all the functionalities to build your own. What is cool with this is that you can have a top-down approach to start making your own generative music; when you land on a generated mix that you really like, you can dig deep and tweak everything. Or, you can start from scratch and create literally anything. There is a lot, a lot, a lot of control over everything, from the sound design and synthesis to the overall structure of the generated music. You don't need to do all this though; you can just launch some of the predefined randomization presets (e.g. drones, pads, strings, pianos) and listen to nice constantly evolving mixes (you can even 'skip' to draw another mix, allowing to really land on your mood). There is a ton of documentation and tutorials. It is the cumulative work of more than 30 years, and you can feel it."  Thank you!

"🔥 "

" I’ve been practicing “rabbit-hole-diving” sports discipline in regards of different types and forms of generative music entity for a while now lol. Started out feeding Mubert algorithm with loops from my productions several years ago as well as created those for this specific implication a bit later - it always got me excited that the machine is able to combine elements that you do well know as the creator but in such ways that they start to form a completely unfamiliar material. Later after these first dives of scratching the surface of generative music, tested out basically every software that I happened to discover (and the pool is getting more and more units as the time goes and this type of music gets more exposure) - some of them are quite impressive and packed with features - such as MIDI in/out support, available as AUv3 etc, etc, etc - some are purely just for entertaining yourself rather than creating anything. So, back to Wotja: Compared to anything that exists out there - this basically is the sickest lab you can think of when speaking or thinking of generative workflows of any kind. Period. And the fact that I’ve discovered it just recently kinda surprises me, ‘cause it seems that the app exists for quite some time. But maybe it’s really for the better - since when you launch the environment for the first time you really do notice that it got to its current state of stability through time of being in active development, no doubt, it’s impossible to fake this stuff - and for the amount of processing it obviously handles in the background it is very safe to say that it’s running rock-solid. Damn, it even supports javascript for the precise control over the real-time composing - and I got my hands on it for some relatively basic tasks and it worked and it really amazes me. Some more HUGE features of this production environment worth pointing out: • AUv3 hosting support in standalone mode, which really promotes this app into the category of DAW - of its own kind. • Custom-made audio engine – if you are familiar with some main titles of iOS music production software (DAWs), then you know that most of them don’t fully rely on their own audio engines and utilize built-in Apple’s system resources for audio processing and vast majority of sound-related tasks, and this is not always the best way to go for sure. From all the software I happen to own for this platform - from GarageBand to AUM, nTrack, NanoStudio etc, etc - there’s only one that I know that developed their own audio processing engine from the scratch - and it’s Korg’s Gadget. Which makes sense - since they are huge as a brand and a company and do have resources to support this kind of ambitions and what’s nonetheless important - to maintain and support its existence in the long run. And the fact that the only software besides Korg’s that I witnessed having the same feature - and really not that much behind in terms of overall stability and build quality - is something that is created by the team of 2 (TWO!!!) men that are behind Wotja developement - honestly, this just blows my mind very faaaaar away. Guys, u f@(l<in’ rock, like - for real. There’s really much more worth mentioning but YOU🫵🏽, reading this review - better just get this lit piece of software installed at this point and find out for yourself loool. No, seriously."  Thank you!


"Been a bit since I went deep into Wotja, so many amazing new features and easier ways to do it. So many improvements in the interface. I have so many hardware boxes, like octatrack, pyramid, ndlr… when it comes to create generative music which is not just random stuff, nothing comes even close to Wotja. You can be musical with it, and shape the flow of the river… Still the Rolls in that field."  Thank you!

"Highly Recommended"

"This is a brilliant and very deep app for all creators and lovers of ambient music. Now works as a VST and supports hosting of VST3s! Superb value, with highly dedicated ongoing support."  Thank you!


"I don't usually leave reviews, but Wotja is worthy of attention and support - the workflow is idiosyncratic ... , but the core app is mature, unique and capable of inspiring results at a bargain price; anyone with an interest in ambient/generative music production should at least give the Lite version a go..."  Thank you!

"Awesome App with Relaxing Ambient Music"

"Absolutely love it! So calming."  Thank you!

"Absolutely magical sounds"

"Absolutely magical sounds, if you're at all into ambient music you have to try this app!"  Thank you!

"Fantastic! Inspirational for artists and relaxing even for beginners"

"I consider myself a beginner when it comes to music composition, but this makes you feel like a maestro in a couple of clicks. This is a deep application that is hard to master, based on my own brief experience and from other users. But, I felt in total control of the music and felt like I was creating some real ambient music to relax to and be inspired by when creating my own music. A great app!"

"Where has this been since ambient scoring?"

"Perfect for the scoring of any whole art, or as good brainwave entrainment drone tones"

"Great fun to play with"

"Lots of options. Somewhat steep learning curve but well worth the investment."

"Excellent for Generative Music"

"I had some experience with earlier versions of this app, and familiar with Brian Eno's use of earlier versions to create generative music. For anyone into this kind of music creation, I think this is a must-have app, it's very good value for what it offers. Great for composers, and also very well worth having even if you just want to have it to run existing creations to listen to (the free app only gives you a few minutes before ending - this one will run as long as you want). Thanks to the developers for their hard work - much appreciated!"


"If you are at all into ambient music and Brian Eno then this is an essential app. It can keep you occupied for years. Intelligent before artificial was added."

"5 Star Generative Music Program"

"A unique program with a brilliant pedigree stretching back many years. I have used many of the products over the years and this incarnation brings new and extensive methods to the Generative Music process. The free "lite" version is useful to learn the basics. The creators respond quickly to queries. Looking forward to using the full version in both its native and VST3 format."


"Wotja is brilliant and is capable of so many configurations and combinations. I have it playing 4 synths on different midi channels. Excellent, great fun, depth and creative potential."

" How unique, how wonderful "

"This app is very satisfying to me. Knowing that music is being generated live for my ears accompanied by beautiful graphics and intriguing oblique messages is very enjoyable."

" wonderful app for generative music "

"i love this app, it’s very special but the best and perhaps the only software for creating this kind of music!"

"The mother of all generative platforms now as VST3 too!"

"This has always been a great tool for generative tinkering but the current version really knocks it out of the ball park. Highly recommended! (If you're reading this, you probably know how you got here...)"

"Woaaaaaa!!!! Yeah, now you can use your own synth :-)"

"Just too cool, no need to use aum, all in one app… and the euclidean generator is awsome… They just took it up to another level… Thx so much for this amazing app"

"Great app"

"Great app simple and really complex both at the same time. On first sight really ease to use and it generates great results with a simple click. But it is also really advanced if you take the time to dive deeper. There are so many parameters and possibilities that it is quite overwhelming in the beginning. But after a while you discover everything and it get's easier to work with."

"Fun to Play. The Depths Require Work"

" I've been using this app almost daily for the last three months gradually chipping away at it's capabilities, which seem endless. This is whether working with the included feature and sound set, adding soundfonts or hosting it in AUM to trigger other apps. The range of music and atmospheres that I've been able to produce is really impressive and with Wotja 22 the recent inclusion of things like Euclidean sequences and the hosting of AUv3 plugins brings even more opportunities. You can get satisfying results almost instantly but there is a lifetime's pursuit for anyone that wants it. Developers have also been friendly and responsive when contacted."

"Seriously impressive tool for generative music"

"I love Wotja, it's extremely deep and has a lot of applications - from using it as a simple sound generator to play ambient textures to using it as an composition tool together with your DAW and existing plugins to generate complex and ever evolving patterns and melodies with unlimited control. You can easily create full scores using only this tool. The new version supports VST3 in the stand alone version or you can load it as a VST3 in your DAW, which makes it all the more flexible and powerful. And all that for a very reasonable price. Highly recommended!!"

"Great App"

"I have loved this program from its beginnings as KOAN Pro."

"I Like Wotja!"

"I use it on my macbook and ipad, it’s a lot of fun. Wotja gets remarkably better every update… and for software with like 30 years of history that’s crazy. Anyway if you’re into making or hearing generative music, or just want to make music in a unique way, I recommend Wotja."

"Wotja Helps "

"Even listening to it in your car. Elicits such a gentle chaos in your life. Having it with you to. Create a finely tuned sound sculpture. I use it everyday. It is a true piece of sculpture for which you can minimize or maximize each through exploration and experimentation. Elicits a Noshic Montality above the heavens."

"definitely recommend it"

"a wonderful app , wonderful developers who listen to feedback of user and are really cooperative; keep it up!"

"Very inspiring!!"

"I've already enjoyed Wotja 2018 etc. on my iPad and am now enjoying Wotja 22 Pro on my Mac. Moreover this App also became a AUv3 which opens in my Logic Pro DAW; so this is fantastic! It's an inspiring App, also when I'm looking for a trigger to start a new composition. And, in contrast sometimes with other Apps and developers, the developers of Wotja are very helpful, give fast support and/or look for solutions when a customer has met a technical problem (which only happened once with an older version). The App itself is very users friendly though. Really a 5 star worth!"

"Amazing app and platform!"

"I have been using this app for a multitude of things since 2009 when it was Noatikl. It's amazing. Super easy to use, great for generative ideas either via MIDI or in-app. It's incredibly intuitive and easy to get started, but also very deep. It always seems like there are new corners to explore, and with scripting you can make your own corners! Can't recommend enough!"

"The one and only Wotja"

"The best ,unmatched in generative goodness"


"SO WOW! Indeed…."

"Intriguingly deep"

"I’m determined to get well into this one this year, as I’ve used various incarnations of it over the three decades of its development and is now just so accessible on each device I work with… I’ve already had it generating sequences of chopped samples using neon audio editor, and I’m looking forward to what more comes of that direction…"


"I have been using this App for a few years now. Year on year there have been many innovations. This year is no exception. The Developers are very responsive. Good set of tutorials on the Website. This is really one of those Apps where the more you put in the more you will get out. It can be very subtle."

"Love it"

"Ok, so it isn't the easiest thing to learn, but for the money it is tremendously powerful"

"This little app can do a lot"

"This little app can do a lot. It has a euclidean sequancer, a software port of braids, wavetable synthises and complex FX chains to name but a few. Throw the dice or tweak every slider the choice is yours. Aimed at ambient generative music but honestly the potential is there for what ever you care to create."

"Great App"

"Really love this app. I use it for background music which helps reduce stress."

Magazine Reviews


"Wotja is really one of a kind in the generative music space, there’s nothing like it at all. It’s really a seriously big bundle of tools, but all in one app, and all with the same purpose. Intermorphic has some serious credentials in this area, having been in the world of generative music for well over a decade now."

User Reviews

"The original and the best"

"There is no other generative music system like this one, with it’s very carefully thought out depth and breadth. It is the original and absolutely the best, and I recall Eno using it back in the mid 1990’s. Since then it has continued to evolve with each iteration. The original developers who first devised it, still own the company and are superb and very responsive indeed to queries. Don’t bother looking elsewhere for a generative music system. Buy this and support Tim and Pete and their unique and valuable life’s work."

"You Need this in Your Life"

"Besides the obvious calming effects having algorithmically generated music composed in real time for you, this app allows you to also author your own experiences. Need 10 minutes of reflection and calming meditative sounds? Turn on Wotja and press play and close your eyes. Done. I have been following this developers work since the release of Koan pro with Brian Eno. This was machine learning before its time. Looking forward to future integrations for visual and musical experiments."

"Stunningly beautiful work"

"The interface is powerful but friendly. The complexity and subtlety is inspiring. The sounds are simply magnificent. And you get a course in Music Theory if you just pay attention. (grin) Great work, folks. Great work indeed."

"Brilliant & Complex"

"As I said, it's complex & brilliant."

"I spend hours..."

"Tweaking this program to discover new musical ideas. The learning curve is worth the climb. Has really set my practice ablaze."

"Amazing software and support"

"This is an amazing software with literally infinite possibilities, it can very easily generate great ambient music but it can also be very complex and generate inspiration for any style. The creators are super passionate and are constantly updating the software with improvements. There’s isn’t anything else like this in the market, it’s surprising how most people don’t know about it."

"Have a synth studio? You NEED this."

"Stumbled upon Wotja Free Version when searching for "generative music" and "generative midi" on my iPad, which led me to their website, at which point I discovered there's a macos version. At the price I paid ($24.99 for the "you-own-it" version), it's less than many of the plugins we all have. As of this writing it works as a standalone app with both an impressive internal synth engine, AND the ability to send out MIDI over virtual midi prots (IAC bus or otherwise). I was so impressed with its ability to instantly about 'decent' randomized-but-pleasant to listen to musical notes (in both midi and its internal engine), that I bought the pro version in under an hour. It's a no brainer with anyone that dabbles in midi-based synth music. In my case, both hardware and VST/AU synths. I'm trying to wrap my head around the extensive capabilties of making your own logical generators, in order to steer it towards my own style and sound using various DAW and 3rd party plugins, such as Omnisphere, which is the perfect partner for the Drone setups. It integrates perfectly with Logic Pro X (10.6.3 at this writing)... Please note this plugin is an AUv3. What that means is, it will not show up as available to Ableton Live (as of this writing), to no fault of Wotja or Intermorphic, it's because Ableton Live does not recognize this new format (yet); I hope Ableton allows for AUv3 soon just because of Wotja's capabilities. Until then the standalone macos app transmits just fine and Live sees the virtual midi ports. I have already captured some great midi streams this way, into clips. The Wotja app also allows for external midi clock (from Live, for example), keeping it all in time. Like I said... if you're like me and have a midi studio of any size, you need this app, and the price is right."

"An amazing accomplishment."

"I have Wotja Pro 21 on Windows, ipad and iMac. iPad version is included when you buy the Mac version. This software can be used at any level you like, from just playing the pesets to digging deep into the internal synth engine and the hundreds of other parameters. If you like Ambient music or are a fan of Brian Eno's instrumenta works then I think you will like Wotja very much. At pesent I have Wotja via interal midi into Logic Pro, playing Labs Soft Piano. The results are incredible! On one level it works in a meditative and mindfulness music tool. I fall asleep listening to a ramdom preset and find it improves focus when working at my computer. Wotja is my favourite music creation software by a good margin. There is also a free demo version. Sincere thanks to Intermorphic."

"Speechless! Software I've wanted since the 80's!"

"Introduced to Jean Michel Jarre, Tangerine Dream and many other wonderful ambient artists, I've wanted to create a wide range of music types under that 'overall genre' name. I recently remembered I had Native Instruments' Reaktor on this old Mac and that finally, started me down this path for 'backgrounds' that I could then improvise over with my modular synth, Wotja though? I just purchased it last night, for all Apples. The amount of everything that I would like to have in a self-generative software package? Finally! Thank you greatly for your decades of work, Intermorphic Ltd! I have finally found a package, answering my needs!"

"A real sonic gem"

"An enjoyable and fun app to use importantly it sounds absolutely amazing offering tweakability and further sophisticated fuctions if needed I can’t wait to pair this with other musical instruments. The customer service has been excellent too."

"One of the most interesting apps I’ve used"

"This has to be one of the most interesting music apps I’ve ever tried. The concept of generative music has been around for a while but this is the first app that’s made it possible to create an entire album, with a level of flexibility and power that supports making something that can be commercially released. The one thing I’d really like to see is more video tutorials showing how to use the app more effectively. While the documentation is extensive, it’s easy to miss features or functions that can improve your tracks and mixes. Overall an excellent app, well worth investing in the pro version. To the dev team; kudos!!!"

"Wotja is THE WAY!!"

"Incredible software for generating ambient music, drones, relaxing soundscapes, meditative masterpieces etc etc etc!! Wotja workflow is a bit confusing at first, but after a solid read of the well crafted documentation and a weekend of familiarizing myself with the program, I’m good to go! The fact that it is now AU is HUGE! I send midi in AUM to all my other synths and create sonic sanctuaries in no time! I will make a new song just for my evening yoga and then just delete it! Feels great! Highly highly recommend. The developers are on top of it with updates, and it’s well worth the price!"

"For almost anyone!"

"So deep and broad in both concept and practical use! For those that only want to listen to music, you have almost unlimited generative music listening bliss with just the tweaking of some randomization settings! For musicians of any ability you can find plenty to keep you creating. Either keep it easy, and use the basic settings, or go all the way down the rabbit hole to challenge yourself for the rest of your career with just this app."

"This is an incredibly fun sound tool/toy!"

"I know the makers of this have been around for years (thank you gentlemen!) and it shows in the maturity and ease of use of the interface. Grab a few patches, slide some sliders, and listen 4ever. Can't wait to hook my hardware up to it."


"The wotja program spawns what melodic music it can generate automatically! And at the same time, there are a lot of settings and functionality to customize the composition and its random rendering as you want. I didn’t think that this kind of program existed at all. I definitely recommend it! and the support service is responsive and responsive. positive goes off scale :)"

"Even more amazing! "

"I originally had this app years ago with a different premium subscription and the new version is absolutely EPIC! If you’ve wondering if the price is worth it compared to other apps, this is NOT like other apps. There’s a moderate learning curve that lets your get started right away and then evolves as you try new things."

"Highly Recommended"

"This is fantastic! A deep rabbithole of possibilities, with dedicated and responsive developers. Essential for producers and listeners of ambient music."

"If you're interested in generative music, this is well worth the money. The internal synthesizers are good, so you're able to generate music even if you don't own a lot of VSTs with appropriate soundbanks, but Wotja can also be used as a MIDI input into a DAW if you do own good VST software. There is a learning curve, but the software is amazing and you will spend hours experimenting with this."

"Koan Lives"

"The first computer program I ever bought was Sseyo Koan because I adored ENO and what the genius Cole Brothers had invented. Now some 25 years later Intermorphic delivers yet another esoteric magic music tool. So glad I found the dark theme and I’ve spent hours and hours in generative music bliss of Wotja since I bought the app."

Best yet!

"I've been there since the Koan days and I've only been using Wotja 21 for about 30 minutes but this is the best yet! I still find the manuals etc a little impenetrable but that might just be me. Anyway, just hit random and you're guaranteed some great results if you're into ambient music. Well done and thanks!"

"Must Have Generative Music App"

"It's had a lot of updates and is still one of the deepest generative apps available. It's been developed over a long period from a number of earlier products and this has clearly helped it build on the knowledge gleaned from those products."

"Wotja makes generative music fun!"

"Wotja is an (almost) superb tool to create generative music *or* just to use it as an endless music player for that matter just a couple of mouse clicks away. The developers (two brothers) are very responsive to questions and suggestions (some of my suggestions really have been picked up by the team and implemented in the next version!). Very good!"

"I never got the urge to review an app so much before."

"After using the free version with the online documentation there was no hesitation to purchase. This app is so deep, flexible and the best documentation I've ever seen. I believe it is under priced for how flexible it is so I got the Android version as well for on the go. Going to be using this is my college degree research on generative music. Thanks Guys:D"

"This is such a great toy!"

"Amazing sounds…, dozens of them. Super variety of flows. Whether you’re looking to create the perfect meditation music, sleepy time tunage, or join the New Age, Wotja will get you where you’re going. Not to mention the sheer fun of just playing with app."

"Wonderful Generative Composing Tool"

"I've been using Intermorphic's Wotja Pro 21 for a few weeks now. Wotja has to be the ultimate tool for creating and composing Brian Eno style ambiences/landscapes I have ever found. It's also excellent for chillout and beats, in fact, I think it could be helpful with making any genre of music. Worth the small price just to play the ever evolving example files. This is truly a masterpiece in generative computer music software which can be used on it's own or output audio/midi into a DAW. Please note, I have absolutely no connection with Intermorphic. Sincere thanks guys."

"Great generative app"

"I love this years additions to Wotja. Overall it’s a very solid app. It plays nicely with everything (midi and synth) on my iPhone and iPad that I have tried so far... I use Wotja usually daily."

"my favorite ambient toy"

"useful, inspiring, and innovative. a classic"

"Way more than just a 'generative music app'"

"Wotja often presents itself as a plug and go generative music app but that does it a great injustice. Much is made of the serendipitous text to music (which it has), it also has a built-in modular synth if you wish to use it but for me its richest feature is as a composer’s tool. If you put in the time to learn it, it can help you quickly compose either note by note or by key or by providing general instructions to its own rule engine. For example, I’ll use a voice to provide a bass line, make a follower voice to create chords from the base line, create another voice to Arpeggiate over the chords played and so on. Using Wotja’s grid, you can go left to right with a few key change variations, borrowed chords or whatever strikes your fancy. Now with the AU3 support, you can control multiple synths easily with MIDI in AUM or some other host. Wotja is far and away my favorite way to kickstart a combo or jazz piece that I later layer on EWI or played parts. With AUM I an mix and match Wotja with drum engines and other tools. Wotja is developed by a very small responsive team and always brings new inspiration with each release."

"The leader in generative explorations."

"These guys have been on the forefront of generative composition since the SSEYO days and have never looked back. Every subsequent version has armed composers with more and more options. The latest update includes an AU plug-in ensuring better integration with the DAW environment. It's the best reason to upgrade to Catalina if you have not already done so. In terms of support, Tim and Pete are to be commended for their quick response to any issues or questions you may have. Check it out and make sure you have the time because the musical voyages will be endless!"

"Been a fan for years... "

"I've used the Sseyo generative music apps for years and it feels like they've all been building up to this. In its latest incarnation, Wotja has really come of age - yes, it can be very deep and a bit tricky to get your head round if you want to control every element, but just let it go its own way and you'll be creating some very interesting, often beautiful music in no time at all. Highly recommended..."

"Powerful generative music app"

"Brilliant software, which can generate complete unique compositions from scratch. Basic functions are enough easy and intuitive to use, and there’re a lot of deep capabilities for serious work. I used this software within many years (from Noatikl V2) and it’s one of my favorite (in the class of midi chords and melodies generators). Technical support is also great."

"Gotcha Wotja"

"I have used Wotcha now for a number of years. It grows from strength to strength. If you like to generate musical ideas this is the app for you. It has quite a steep learning curve but don’t let this put you off as you will be rewarded for your efforts."

Google Play Store

"Class! How can an app be this deep. Its like it should need a high powered computer but it works flawlesssly! Thanks guys :D"

Amazon Appstore

"If you are interested in generative music, this is the best software to learn."

"A whole new thing"

"This is a new generative thing--endless and yet intimate. Amazing for working on screens-- the flow setting is just the right amount of auditory stimulation. Use good speakers and get immersed."

"Explorative ambience "

"... it can also even with no effort generate tremendously beautiful tracks that will leave you absolutely stunned. The inclusion of MIDI out now makes the app a real aid to swiftly make interesting non melodic content. A joy to use and explore"

"Best app for generative music, nothing compares."

"Wotja is unequalled for generative music software. The way the tracks interacts in a way which makes musical sense isn’t found anywhere else. They are the expert in the field, learning from their past, from Koan, Mixtikl, Noatikl... To really get the most out, you have to spend the time learning it, neverless just putting a random “jam” on can sometime sound better than anything else."

"Best Thing Since Eno Picked Up A Casio"

"Sliced bread everywhere, can't talk too busy, things to do."

"Simply the best ambient app ever made!"

"It looks complicated, there is a little learning curve and it does take a little time to learn. Once you know your way around it is very easy to create ambient masterpieces, from single tracks to entire albums. This app produces endless amounts of totally unique ambient music. Amazing!"

"Essential music app"

"This app is vital to my workflow and music creation. Whether I am using it’s generative midi capabilities or micro editing the onboard synths, Wotja has made making music with iOS so enjoyable and productive. I don’t know how I ever made music without it!"

"Koan Lives"

"The first computer program I ever bought was SSEYO Koan because I adored ENO and what the genius Cole Brothers had invented. Now some 25 years later Intermorphic delivers yet another esoteric magic music tool. So glad I found the dark theme and I’ve spent hours and hours in generative music bliss of Wotja since I bought the app"

"Once again a great artistic application"

"I had already purchased the version for the Mac and now I have purchased the version for my new iPhone, the audio rendering is superb and the compatibility with the tracks created with my mac is complete. The developer is a very kind person and always ready for requests for help or clarification, which should not be underestimated in the boundless panorama of applications that sometimes are not even updated. 10 and praise for this software!"

"Fascinating App..."

"Endless possibilities and terrific support!"

"Ambient Music Maker"

"Great experimental software"

"Combination of power and useability"

"It's an incredibly satisfying piece of software to use. I enjoy the pieces I create, and expect to get better at it as I gain familiarity with what the package can do for me. An(d) the price is way cheap, for the use I'm getting out of it."

"Hugely Powerful"

"This is an astonishingly powerful bit of kit... The range of options and control you have over your sounds is immense... Make no mistake; this app is wonderful."

"Brilliant musical playground for creating, inventing and relaxing"

"One of my best app purchases this last 12 months and I’ve bought quite a few."

"A drone and ambient enthusiast loveletter"

"I just love letting it run endlessly savoring the ambient and different arrangements, experiment with it and I feel I even didn't scratched the surface."

"A gem"

"Love this app for relaxing."

"Great quality generative music, I had SSEYO Koan Pro back in the day, this is so much easier!"

"Power to make it your own. "

"We all want to make it our own. This is it. Not that it is easy but it is worth it. Why build on others work and be told later you don't own this. There is great potential in this software"

"Must have for generative music"

"Very deep app for generative music - the best I think. Very good support from it’s developers. Strongly recommended."

"Try it ... your mind will expand!"

"The devs are very responsive and very nice. There is nothing like this out there... and believe me I’ve looked. "

"Refreshing!!!! "

"First of all, the developer(s) are amazingly responsive, helpful, patient, kind, and enthusiastic. Communication is a pleasure. It's an otherworldly environment that helps inspired creativity."

"Wotja is excellent!"

"Best generative music product I own!"

"Very good software"

"I bought this software to create ambient background music for relaxation and meditation. This software is just perfect for my needs and easy to use. Also the export features are great. Thank you guys for this amazing music creation tool."

"Helps you approach creative creation with different work flows "

"This app is fantastic you can quickly begin to generate something inspirational and add hone to find something by exploring. The depths of the app are there to discover and explore at your own speed and need but is not a bar to making and creating with little or no musical or synthesis knowledge. The multiple creative workflows mean that you have many ways to generate projects and don’t fall into one groove. Wonderful and inspiring the app is a piece of art unto itself."

"Instant gratification, infinite possibilities, endless wonders "

"The king of generative apps ... and capable of pretty much anything from classic Enoesque plinking to cavernous Steve Roach dronescapes. Complete non-musicians can produce works of compelling brilliance by just following their ear and taste, while seasoned musoes can turn a vague intuition in their head into endlessly unfolding sonic magic."


"Wotja can be as simple as a visual and auditory experience that mixes written words and generative music... Wotja can also be a very deep modular environment where you can edit every aspect of your music and sound parameters... I don't think I'll ever get to explore all of Wotja's features, but I do learn new things every day with the help of Intermorphic. Anytime I hit a wall, it gets knocked down pretty quick with explanations for those little things that aren’t readily apparent to me."

"Wonderful app"

"I have been purchasing Wotjas with every update for years. It’s the only app I have done that with, ever. I love how I can choose to go as deep as I want into crafting soundscapes while at the same time have the option to just "one click" load beautiful pre-made yet randomized songs."

"mad value for an unlimited creative powerhouse"

"A stunning start-of-year launch price for the single-purchase version of this titan of an app."


"An excellent music-making tool of almost unlimited depth, with strong and sympathetic support."

"Serves Well"

"Great piece of work!!! Thank You."


"As an accomplished musician in my own right, investigating alternative means of generating sound is a longstanding interest of mine. Even after a thirty year career in the arts, this app has completely changed my perception of the concept of music itself! I implore all students of music to explore this software in its entirety- this past week has had me rediscover my love for creation."

"The Most Advanced Generative Music and Sequencing Solution, Period"

" ... Wotja benefits from the long pedigree of related generative music apps, as it comes bundled with plenty of their content. There are lots of little apps that will bring some measure of generative/aleatoric aspects to your music, but none can offer the depth that Wotja delivers. I’ve used it to sequence hardware and iOS synths without issue."

"Great app, complex, deep and unique"

"I'm an engineer, I like tinkering, I like creating stuff, I like music sound and synthesis, I like puzzles ... I love Wotja. Such a cool app, very flexible and deep. It really can be quite addictive, challenging, complex and fun. Ticks all the above."

"Simply the best"

"Probably the best generative music app on iOS. I’d wholeheartedly recommend this to anyone with an interest in music making."

"Superb package for ambient music creation"

"Wotja a complete package for the creation of ambient, generative music. Offering complete and comprehensive control of all parameters, it makes possible gorgeous, ambient music. As someone who has been creating this kind of music for a while, Wotja enables me to achieve my vision in ways no other software can. The monthly subscription model is a total steal; if you need support, it’s fast, technically sophisticated, and patient. The latter is important as I think I have asked every dumb question I can about the software. The support people are unfailingly friendly and very helpful. If you have the ambient gene, this package is for you."

"Exceptional Dimensionality"

"I have been in love with Intermorphic products since the days of KOAN Pro. Wotja 19 adds a whole new dimension to creativity and playback for professional musicians and rank amateurs like myself. This program is awesome!"

"An excellent app!"

"I've used Intermorphics products since Liptikl and Noatikl 2. They've been an indespesible part of my creative flow for a long time. I held off from switching from my trusted Noatikl 3 app for a while, but finally made the switch to Wotja Pro 19 and I couldn't be happier! I've been moving all my old Noatikl files over and am re-programming my scripts for Lua to Javascript. I'm really happy with the improvements since Noatikl!"

"perfect for what it aims for!"

"... this is a dream. I am freaking out at how scary or lovely you can get."

"Amazingly powerful!"

"Sounds great on its own. MIDI & audio export. Top notch support by developers. Hours / days / years of fun!"

"Worth spending the time learning it"

"It’s deep... takes some real effort to go deep, but then you realize the real power of it, from patterns, scripts and all... you can produce some happening stuff with it :-)"

"Love this app!"

"I have been a Wotja user for several years and it’s always a pleasure to to re-purchase whenever they create a major upgrade. There’s SO much in this app. You can really geek out on the smallest of setting and yet it’s also pretty easy for new and not-so-musically-skilled person to get going with."

"The Best"

"I'm really fond of this app. I use it in both simple and advanced ways. The sound quality is excellent. The sounds have a beautiful crystalline, digital quality that is clean, refined, and unique, better what most music apps can do. The obvious strength is endless ambient listening, but there are deep parameters and with a touch of creativity and inspiration one can use the platform as a jumping-off point for fascinating generative composition, especially if you have a mind to export midi into DAW projects. Thanks very much to the developers. A magical app! I hope they keep refining and updating it as they have now for such a long time. Unfortunately this app is one of a kind, and I say unfortunately because when it comes to generative platforms it's one - and probably the best - of only a few options that I’m aware of."

"Wotja think of it now?"

"AirPods and Wotja Flow. Heaven."

"Amazing Stuff!"

"I love the textures I’m getting already. If you’re thinking of purchasing, it’s well worth the price!"

"Fantastic support"

"Wotja is a fantastic generative sound canvas that you can control - or just listen to. It can be as easy as loading one of many included mix albums, to the generation of random mixes, to manual mix editing to actually getting dirty under the hood with the voice editing and the instrument design. It goes pretty deep!"

"Works well"

"This company is fantastic at what it does."

"A vehicle, a journey, a playground"

"All the toys, and far more than the sum of its parts. (Autocorrect had it as "more than the sum of its arts", which is actually more accurate)"

"Generative Music Masterpiece"

"These guys are Ambient legends and now we can all work with their tools. Create your own ambient tracks or use Wotja to create some initial ideas to build upon. I use this to quickly bang out some background music, but mostly it is the starting point for composing. I find having Wotja build a nice little background bed I can compose over; my tracks go places they never used to (in a good way). Wotja can be used as a stand-alone app or as just one element in your songwriting toolkit. I really love Wotja. A lot!! ... When you think of the fact that these guys helped develop ambient music generative technology from its infancy, then supporting them by buying the app only makes sense."

"Fantastic App!!!"

"Get the free version, try out everything for 3 days or just buy the current yearly version. You will not regret it!"

"great compositional tool"

"an indispensable instrument for widening your scope, when it comes to composition. Thank you for your work!"

"Surprisingly good results"

"This app is so much fun and the results are often beautiful and interesting. The cut-up technique lyric generator is worth the price. It's flexible enough so that you can steer the direction of the outcomes and continue to refine until you find something you like. I don't think there's another program like this."


"Loving this application! A great way to explore some amazing sounds and create new music. For all of it’s depth it’s incredibly easy to get started. Tech support is phenomenal. These guys really care about what they build! Highly recommended!"


"... a specialist app for making generative music ... the developer goes to great length to make it as accessible as possible to all (without losing the appeal for more experienced users). I really like it ... Recommended."

"Deep and professional app"

"If you loved Noatikl and Mixtikl then checking out Wotja is almost required. The guys at Intermorphic Ltd have wrapped up all the great stuff from the earlier apps and delivered them here in a beautiful package. I consider it my number one composing tool when I'm working in the Ambient genre."


"Intermorphic continues to produce brilliant apps. The possibilities of Wotja are vast and deep."

"Unique App"

"A unique app, which is getting lots of updates. Very deep, it requires considerable time to delve into it's complexities. It's well worth it though, in my view."

"Best generative music app"

"There is so many possibilities on this app. The creators are super nice people, theres only 2 of them but they do answer very quickly and are not greedy... It really scares me to think that the developers would stop supporting and growing such amazing tools, please don't! Much love"

"Completely changed my mind"

"I recently purchased the "pro" (non-subscription based) version of this. Like any musical instrument, it rewards more practice and play. And the fact that there are so many parameters to tweak, change (or not - you can use templates and leave them alone, but where's the fun in that?), modify, etc, only makes for more surprises and creative experimenting. You can just experiment, as with modular, old-school analog hardware, and see what happens. And quite often, there are very satisfying results. This is very powerful software. These guys are ***THE*** pioneers along with Eno in generative music. They clearly love it and deserve to make a decent living and be supported for their long-term and continuing work. Highly recommended."

"The perfect sleep machine."

"Intermorphic is awesome!! I was a little hesitant to purchase another subscription service, but it all really factors out to only about a dollar per month. Wotja is hands down the best generative software that I have ever used. Extremely musical. Keep up the good work."

"Still the best MIDI composition tool in my toolkit"

"Keep in mind that even though the app is associated with "generative music" and ambient sounds, it is possible to create music in any genre with this - its possible to direct every voice to play note by note OR just tell a voice to improvise OR tell a voice to follow and/or harmonize with other voices. ... nothing gives this much control to a composer on iOS and I've tried almost every sequencer, generator, MIDI tool available. It's very much worth learning, the developers are responsive and there is a great website for support."

"Light years ahead!"

"by far the most sophisticated and powerful generative music application available."

"Every kind of amazing"

"Intermorphic's apps have always been strong on interoperability, but here they've managed to combine what is effectively Noatikl 4, Mixtikl 8, and Tiklbox 2 into a single beautifully-designed all-in-one generative mega-app – putting an end to all the copy-and-paste faffing that used to be involved if you wanted (e.g.) to use Noatikl content in Wotja. ... this is the culmination of everything Intermorphic have done, and an all-in-one machine for the creation of wonders."

"having the time of my life"

"It was amazingly easy to connect to my PC DAW with rtpMIDI so I can use my own sounds but it's hardly necessary, the latest Sound Engine is excellent. I thought I'd just say...excellent job. Thanks."

"Professional grade!"

"Wotja ... is the most powerful and feature rich application for generative music creation."
