Deep, Unique & Fulfilling

Wotja History

From a double BAFTA award-winning development team, Wotja is the continued evolution of the legendary 'SSEYO Koan Generative Music System', Noatikl, Mixtikl, Liptikl & Tiklbox. It uses a combination of AI Techniques & heuristics we’ve been crafting for nearly 30 years and is going from strength to strength.

Background: Generative Music is a term coined in 1995 by Brian Eno whilst working with SSEYO Koan Pro.

App Range

Wotja V19 App range: There are 4 different versions available in 2019:

For All Users (Play Music)

All Wotja apps include the fun 'Flow' mode to create a succession of auto-generated and relaxing mixes. To change what's generated simply select or edit a Randomization Scheme in Settings.

For Mid-Range Users (Play & Create)

With a Wotja Box 19 app, create/edit/save albums of auto-generated mixes, plus get a longer play time.

For Pro Users (Play & Create)

With a Wotja Pro 19 app or a 'Pro' Subscription tier, create/save custom generative music compositions, mixes & sound designs, generate multi-channel MIDI, get an even longer play time + lots more.

Yet More Uses...

  • Generative music does not have to be calm and relaxing; experiment with both composition (IME) and sounds (ISE) to make it as abstract, chaotic, noisy or experimental as you like!
  • Play live & "timeless" ambient generative music for installations, small shops etc.
  • Create & record your own custom, high quality, license/royalty free background music for videos, CDs etc.
  • Create automatic albums and playlists of mixes
  • Drive other MIDI synths via MIDI Out
  • Open Wotja, Noatikl, Mixtikl & Liptikl files

Wotja 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."

Wotja User Reviews


"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"

"When I was a young lad long ago, I downloaded a free demo of Sseyo’s Koan, the long-lost ancestor to Wotja. I was quickly entranced by the idea of generative music but as a young man I was unable to afford Koan’s price tag. Fast forward to 2k19 and Wotja takes many of the original Koan ideas and expands them. In fact, 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."

"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."

What can I do in 'Free Mode'?

  • Create/save automatic albums of generative music mixes (each mix is of 30 second duration; editing/saving of albums is not supported).
  • Full use of Edit Mode to create, save and export generative music mixes (which can play for 1 minute) and cut-up text.
  • Up to 10 minutes music play in Flow mode where mix durations are governed by the Settings > Albums/Flow > Mix Durations parameter.
  • Up to 10 minutes music play in the Album player of ANY .wotjabox album.
  • Explore generative music composition and sound design:
    • Use the Intemorphic Music Engine (IME) editors to try out all sorts of generative techniques and end up with something totally custom; start with the generative settings in the available templates if you want.
    • Use the Intermorphic Sound Engine (ISE) editors to create totally custom modular synth/fx sound networks, including using your own SoundFonts; start with the sounds in the available templates if you want.
  • Use MIDI Out/In on Channel 1
  • In-app support for audio (and video where supported) mixdown recordings of up to 30 seconds; you can also make up to 1 minute recordings of Wotja mixes as follows: on iOS using Inter-App Audio or Audiobus (and a suitable audio/MIDI recording app) or on other devices using any app that can record system audio/MIDI.

The benefits of 'Free Mode' for Creators

  • For free, use what you create, save & record (do still comply with the EULA and Terms of Service however)!
  • If you have an interest in Generative Music and you are someone who chooses only to use Freeware and/or if you are an Educator or in Education, then Wotja 'Free Mode' means you can explore and work with such things for free. As Wotja is a system that is undergoing continuous development, including being ported to other OS, it should be an app you might well wish to consider using!
  • When you find you want to do more than you can in Free Mode, then there are low cost Subscription options and/or Paid-for versions you can purchase.
