Wotja 4

Reflective Music System

With Generative Music

Wotja is our music creativity app for creative relaxation & chilled-out reflection and peace.

At its simplest, add some text or emoji and it will create beautiful evolving melodies with a selection of live ambient generative music backings.

However, as you would expect from a team that has continuously honed generative music engines, tools and sound technologies over the last 26 years, there is way more to Wotja than that! In Wotja 4 we now consolidate some of the best of Noatikl 3, Mixtikl 7, Tiklbox as well as Wotja 3. Plus, we have taken it forward at the same time.

It is the sheer depth of what you can do after you add your text that makes Wotja a truly unique music app and,in its own right, a powerful reflective generative music publishing system. That also explains why the User Guide is quite big; if you want to dig deep then you can.

If you've a few minutes to spare then why not take a short creative break with Wotja? Although it is a very deep app, we are always working on ways to help make it quick and easy to get into and use. It makes a refreshing change, too, from other kinds of entertainment such as playing a game!

Wotja 4 includes all the generative templates that came with Noatikl 3 and Mixtikl 7 (and allows import of Noatikl and Mixtikl files) , and we will be adding new templates in the future. You can also use a background image if you wish. For those who love tinkering and delving deep, it includes full ISE 4 Network and Unit editors for sound customisation as well as the full editors for the IME that have come across from Noatikl mobile.

You can easily share your wotja as a file by email, or embed it in a webpage as a Wotja URL. Go ahead, express yourself…

MIDI & Audio for power users:
Via Core MIDI / Virtual MIDI / MIDI Clock*, use Wotja as a music generator to drive other MIDI synths for e.g. ideas and live performance. Inter-App Audio and Audiobus are also supported in Wotja.

How to play a wotja:
On your iOS device either make one, try one of the included demos, open a wotja email attachment or visit a webpage that includes an embedded "Wotja URL" (see: Examples).

Playback requires a user to have Wotja installed.

It all started with Vector Audio

One of the fun things in Wotja is that you can export your wotja (including all settings necessary to create the sounds and FX) as shareable URL-based "Wotja URL", a capability that draws on aspects of work on "vector audio" that we pioneered at SSEYO in 2000.

FAQ - Wotja

Important: Have an issue with subscriptions?

We have today, 18th Feb, submitted Wotja Pro 2017 for Apple review. For further in depth rationale behind our recent changes see this forum post.

What is an in-app subscription?

An in-app subscription is just a mechanism that lets you pay to access certain features in an app for a set period of time.

We now use them because they will help us fund our continued development of Wotja over an extended period of time.

Subscriptions are not the bad thing some people might claim or fear they are, especially when used by a bone-fide developer that creates high quality paid for software that does not treat you as the product.

They mean we spend more time working for our existing customers rather than spending that time in trying to find new ones.

They also mean that during your subscription period you should continue to see improvements and new features that we would previously have had to hold back to charge for in another new paid-for version of the app.

The above mean it is a win-win for both the customer and developer.

What are "auto-renewing" in-app subscriptions?

These are just subscriptions that will auto-renew when they expire without the need for you to set up a purchase all over again. They are convenient because, for something you love and use regularly (hopefully Wotja!), you do not need to make a new purchase each time the subscription ends. Your creative relaxation is uninterrupted. They are very easy to cancel though, see below.

Is it easy to cancel my subscription?

Yes, it is very easy to cancel your subscription and you can do so at any time up to 24hrs before it renews. You may even decide to cancel it just after you purchased it - that is your choice.

What happens if I cancel my subscription?

All that happens is that at the end of the subscription period Wotja will revert to FREE operation, i.e. the feature set and capabilities you can user for free. If or when you decide you would like to start a new subscription you can do so at any time.

How do I cancel my subscription?

Apple provides detailed information on managing subscriptions. Please refer to : https://support.apple.com/en-us/HT202039

In Wotja:
  • Go to the Wotja Store and press the "Manage Subscriptions" button (it is shown in the area marked as "Miscellaneous".
  • You then see the Wotja subscription page and you can see what level of subscription you have.
  • Press the "Cancel Subscription" button.
  • Press the "Confirm" button in the pop up.
  • Your subscription will no longer auto-renew.
  • At the end of the subscription period Wotja will simply revert to FREE operation.

How is the subscription price decided?

It is up to the developer to set the price for the subscription and they will balance many factors (it is ultimately a cost/return equation). If the price is too high then the IAP is not purchased; if too low the app will eventually be abandoned and die because the costs are too high or returns too low. Getting that balance right is an art, not a science.

How does Wotja 4 subscription pricing stack up?

If you were to purchase Noatikl 3 for iOS, Mixtikl 7 for iOS, the old Wotja 3 for iOS (no longer available) and the 2 Albums in Tiklbox for iOS, it would cost you around $29 USD (or equivalent in iTunes pricing). If you worked part of that as a bundle it would be around $25 USD.

A 6-month subscription for Wotja starts at just $5 USD for the ESSENTIALS feature set (a massive saving on the above), or or $15 USD for the PRO set. You can also try all the Wotja features without having to first buy it (see the feature comparison)!

It works out a great deal because during your subscription period you will have had all that power in Wotja for less than you would otherwise have paid as above. And, as noted above, during your subscription period you should continue to see improvements and new features that we don't have to hold back to charge for in another new paid-for version of the app.

If you decide not to continue with your subscription then Wotja just reverts to FREE operation.

If you just don't like subscriptions?

That's OK, you can purchase Noatikl 3 for iOS or Mixtikl 7 for iOS (or a bundle) for as long as we keep them available for sale (TBD). There will be no further feature updates for those apps, however.

We hope the above info helps

We want you to be clear as to what subscriptions are and why we now use them. If you purchase a subscription to Wotja then you get our eternal gratitude and you will know that you have encouraged us to continue development of our generative music tools. Thank you!

Wotja for iOS is our primary music app for 2017 and beyond. It is free to use and there is a lot you can do for free, too.

If you already have Noatikl for iOS or Mixtikl for iOS we suggest you try it (you won't know what you're missing), but if you are happy with their content, features and interfaces then you are under no obligation to get a subscription for Wotja - just carry on as you are! See our FAQ entry on in-app subscriptions.

Our Noatikl and Mixtikl Desktop versions continue to be important, too, for our Desktop users (See these FAQ entries: Noatikl, Mixtikl).

You might want to consider getting Wotja 4 for iOS if:

  • You want to use any of its cool new features.
  • You want to continue to play your Noatikl / Mixtikl pieces if your OS version no longer supports your Noatikl or Mixtikl apps.
  • You are a fan of our artisan "creative relaxation" tools and what they mean to you, and you want to help support us in our efforts to continue developing them for you.

Note: Wotja 4 for iOS does not interfere with Noatikl 3 for iOS or Mixtikl 7 for iOS installations and should work fine with pieces you have made in previous versions of Noatikl (mobile or desktop) and many mixes made with previous versions of Mixtikl (mobile or desktop). As Wotja 4 is free, you can easily try it out with your Noatikl and Mixtikl pieces (see: How to copy Noatikl pieces and Mixtikl mixes into Wotja 4). You may even want to try out creating some new random mixes!

No, sorry! All our previous major versions followed a Fullgrade pricing policy meaning they are already priced as upgrades. Wotja 4 is a major new app from us that consolidates some of the best of Noatikl, Mixtikl, Tiklbox and Wotja 3.

By default we hide the older Noatikl 2 templates simply as our current templates are so good! They are included, however, and it is easy to display them. Simply go to Files > Create New > Templates > and turn on the toggle that says "Show Old?". Once you have done that, the older templates will show up in the template list in a dark grey colour.

These are not included in Wotja 4 as we now have a new set of gorgeous sound presets and templates (you can also export favourite presets from these, too). But we are making them available if you want them; see below.

Tip: You see the included TG Preset list from the Network Editor screen. Select the "Action" button and then "Open".

Older Presets: Download a zip of the TG presets and place that in the Intermorphic Folder or zips folder under that.

Once the file above is copied to the right place, you may need to restart the app for the older Presets to be displayed.

General comment: The Intermorphic Sound Engine (ISE) Sound Units (Wavetable, Tone, DSynth, Particle) run in stereo. In earlier iterations of our sound engine these units ran in mono, even though the FX Units worked in stereo. Running the Sound Units in stereo does place a higher load on the processor, however, it greatly improves the sounds that the ISE can generate so it was an essential change we had to make.

You can get performance issues if the processor in your device is trying to do more that it can handle, and there are a number of possible reasons for this when it comes to using Wotja. You can also get some audio artifacts occur in the ISE from "note stealing" (see below). However, before we look at any of those, there are some general things to check / note first when it comes to conserving processor cycles so that the app can use the maximum processor power available.


  • Use latest iOS version: Ensure your device is using the latest iOS update available for it.
  • Power cycle your iOS device: This just ensures there is nothing running you don't expect to be running. Tip: Even if no other app is running, this can sometimes solve problems that seem to have no obvious cause.
  • Other running apps: Although mobile OS are good at managing app usage these days, it might well be worth closing all other running apps.
  • InterApp Audio / Audiobus: Use of these takes up processing cycles, so try working without these on (at least until you have found an approach that works for you).
  • AirPlay, WiFi, Bluetooth, Cellular data: Use of these takes up processing cycles, so try turning these off. Why not try temporarily putting your device into Airplane mode?
  • Don't run Wotja backgrounded: There are less processor cycles available to the app when backgrounded.
  • Cable connection to computer: If your device syncs, that, too, can use processor cycles, so try using it without a computer connection (but charging it from a USB charging point is fine).

Try these (in order):

  1. Audio Output Setting: The Wotja 4 default audio output is 44Khz stereo. However, runnning at 44Khz stereo places a higher load on the processor. If you are having performance issues, this is the first thing to try changing.
    • Solution: Try setting Audio Output to 32Khz Stereo or even 22Khz Stereo. Wotja Settings > Audio Output.
  2. Airplay: Airplay uses processing power to stream the audio, so if you are having performance issues please first ensure this is off:.
  3. Templates/Content/Tracks: To make the new templates sound really great they take advantage of the stereo sound unit capability (above) in the ISE. Some templates feature synth (and generator) networks are really quite complex, too, meaning they will use more processor cycles. The processor useage therefore greatly depends on the templates/content being used which means that some of the demo mixes will take up more processor cycles than others. Also, how you configure the ISE can also play a part.
    • Solution 1 - Templates: Either use fewer templates/tracks in a piece so there is less sound to generate (in some of the Demo pieces use 3 merged templates but even that can be too much on some devices!), use less complex sound generators (such as templates that have a sound network primarily based on Wavetable units), or look to remove some FX units that are used in a template (you can do this via the ISE Network Editor).
    • Solution 2 - Note Stealing: When the IME generates a lot of overlapping notes and the ISE is generating the sound then unless the ISE Polyphony setting is sufficient to cover all the notes that may be playing at the same time you can get an effect called "note stealing". This means a newly composed note will play in preference to the a previously generated note, on a First in First Out (FIFO) principle. The last note is instantly "dropped" meaning it can cause a click, especially if you are using FX. See the Polyphony setting in the ISE Network Editor.
  4. Track and Global FX: Our current templates are generally sonically richer than earlier templates (such as those from Noatikl 2 and Mixtikl 6 and earlier) and most use a reverb and other FX in the template itself. If you have a lot of Voices in your piece, then a lot of FX units can be in play at the same time.
    • Solution: If using these new templates in a (merged) piece, try removing FX from the templates themselves (e.g. reverb, as that is a heavy hitter), and then add it back as a Global FX. Example: Copy one template's FX network to the the clipboard (ISE Network Editor > bottom right Action button > Export to clipboard) and then pasting it into the Global FX (ISE FX Network Editor > bottom right Action button > Import from clipboard) and then remove the FX from each Voice's FX Network. This may change how the piece sounds quite a bit, so may require some experimentation.
  5. Merging pieces: Because of the Wotja 4 template richness (above), you do not need many when creating a piece.
    • Solution: Try merging no more than 3 templates. This should still give you PLENTY of goodness to play with.
  6. Use some older content, too: Because of the Wotja 4 template richness (above), you do not need many when creating a new piece. However, we still include the older Noatikl templates which in general has less of a processing hit, so you might want to try sprinkling some of that in.
  7. Try to isolate the issue: If you have got this far down the list and are still getting issues, such as ocasional clicks, glitches or pops etc., then it may be that the issue is coming from your piece and it might be worth seeing it you can isolate the problem. That means gradually removing IME Voices and ISE Sound Networks from your piece / mix until the problem goes. Then you can work back up again.
    • Optional - MIDI Out: If you are STILL getting audio issues then it may well be worth trying to play the IME MIDI note streams via external/3rd Party synths (using MIDI Out) and seeing if the issues then go... If they do go, then it is likely the issue is something related to the ISE...
  8. Your Device....: We put this at the very of this list because we know only too well that money does not grow on trees and powerful mobile devices are very expensive. :( But, the device you are using is also a factor to keep in mind. How our app sounds is very important and, to keep moving forwards, we have to to take advantage of new capabilities and device power - we do this very carefully though. Unfortunately, sound generation and sound processing is a heavy hitter, and, moving to stereo sound units (see ISE comment, above) is just something we had to do...
    • Solution: If your funds allow, it might be worth at some point checking out a more powerful device.


If Wotja isn't making any sound, first check that you have the "ISE for Sounds & FX" toggle turned on in Settings. If this is on, then Wotja will automatically render all MIDI data that it generates through Wotja's built-in Intermorphic Sound Engine, and you should hear Wotja playing (unless you've turned-down your computer's volume). If the checkbox isn't ticked, Wotja will only send its MIDI data to whatever MIDI Output destination you have defined in Wotja's MIDI Out settings... which means that you've probably got a bit of MIDI configuration to do first in order to hear Wotja play.

Note that Wotja can play both through ISE and through a MIDI device, if that is how you have configured things - the choice is yours.


Don't forget to press play. Make sure your system volume is turned-up, and any speakers are turned on. Make sure you haven't muted all voices, or set their volumes or velocities all to zero. If you are using fixed-pattern voices, make sure they don't all have empty patterns.

Of course you do not need to attribute Intermorphic! If you wish to, though, then please do!

Please note, though, that unless you had an active, paid for subscription when you made the recordings they may not be used for commercial or business purposes. Please also ensure you comply with the licence terms for any Tiklpak and/or 3rd party content you use in your recordings.

In general, yes you can. For further details and clarification around the Audio Loop paks see here.

Please note, though, that unless you had an active, paid for subscription when you made the recordings they may not be used for commercial or business purposes. Please also ensure you comply with the licence terms for any Tiklpak and/or 3rd party content you use in your recordings.

Yes, you may, but see here for further details.

Exporting to the clipboard:


In Mixtikl, select the Content Cell you are interested in (the cell content must be generative i.e. not audio loops) and from the Content Cell menu select the Export button and you will get a message saying that the data has been exported to the clipboard.

Note: When you export from a Mixtikl content cell the Track FX are NOT included (but Cell FX are).


In Noatikl, go to the Pieces screen and then select the export button on the bottom toolbar. You will get a messages saying the data has been exported to the clipboard.

Note: If your Mixtikl content cell used a custom Wavetable/SF2, then you need to have that available to Wotja and you may need to recreate the association.

Importing from the Clipboard into Wotja:

  • In Wotja, go to the Design view, select a Cell and then select the Action button on the bottom toolbar. You will get a pop up dialog givng you the option to "Merge from Clipboard" or "Replace from Clipboard".
  • Choose the option you want and the content is imported and ready for editing.

See the examples section.

We hope to add further examples in due course.

We will be creating some video tutorials in due course.

You cannot record MIDI files directly in Wotja. You will need to use a 3rd party app to do that, using Wotja's MIDI Out capability.

Older format "http://" Wotja URLs included references to the underlying templates being used together with any user made changes to a small range of parameters. These URLs did not include your text or note patterns, either. The foregoing kept the size of the URLs small enough to be tweeted, but the approach was very limiting.

In Wotja 4, however, we have greatly expanded what gets saved to the the Wotja URL. It now includes *all* IME and ISE parameters, text and even images and Wotja files can now included multi-cell mixes! This is much better longer term but it does mean the WJURL is now way too big to be included in a tweet link to be shared via shortening.

So, we have changed our approach to sharing/publishing in a way that is much more powerful and flexible. Wotja 4 now supports "full" wotjas being embedded in webpages as "wotja: //" URLS, and without any coding at all. These wotjas can include your text, note patterns and mixes with as many pieces/voices as you care to use - and even a background image. Of course, you can design your webpage to look as beautiful as you like - maybe even displaying the words you use in your wotja!

To complement this approach we have created a Wotja Extension for Safari, available via the Mac App Store. All you need to do is embed the wotja in a webpage and then share a post/tweet that includes a link to your webpage - this also makes it clearer to people where they are going to with the link. With the Wotja Safari App Extension enabled, the webpage embedded wotja will play once the the page has loaded.

Finally, using webpage embedded wotjas also provides a simple way for you to let people download and play such "full" wotjas in Wotja for iOS - that not being possible before, either.

Try this example.

When you visit the link to the Dropbox shared Wotja file in Safari then you will see a page of text - this is the Wotja URL.

Desktop Safari:

  • If you have the Wotja Safari App Extension installed then it should start playing

Mobile Safari:

  • Not recommended (WJURLs are LONG): To play this in Wotja iOS you must copy ALL the text to clipboard and then import it into Wotja - from the Files screen Action menu select "Import". You will be asked to give the file a name.
  • Recommended alternative: For mobile sharing of a Wotja URL, embed it as a link in a webpage and then share a link to that webpage.

Intermorphic apps that support Apple iCloud / iCloud Drive:

  • Wotja 4+ (iOS), Wotja 4+ (macOS)
  • Noatikl 3.0+ (iOS), Noatikl 3.1+ (macOS)
  • Liptikl 2.0+ (iOS), Liptikl 2.0+ (macOS)
  • Mixtikl 7.0+ (iOS)
  • Wotja 3.2+ (iOS)

iCloud Drive Folder:

The iCloud Drive folder on macOS is found here:

  • ~/iCloud Drive/Wotja/
  • ~/iCloud Drive/Noatikl/
  • ~/iCloud Drive/Liptikl/

Why use iCloud / iCloud Drive?

We strongly recommend using iCloud / iCloud Drive wherever you can.

There are five main reasons for that:

  1. Backups: Files kept in iCloud are always backed up.
  2. File Synchronisation: Lets you easily create and edit on any device. For example, on an iOS device you create a file on device 1 and then edit it further on device 2, and then on macOS work on that file in the desktop version of that app, and vice versa.
  3. File Organisation: You can move files around on iOS with the iCloud Drive app or on desktop PC with Finder.
  4. Single copies of Zip files (Wotja 4 only): If you Zip up additional content that you want your Wotja file to reference (e.g. SF2, WAV or OGG files) and you put that Zip File in the Wotja iCloud folder then you only need one copy of it (rather than a copy in the Intermorphic Folder of very device you use).
  5. Simplicity: You don't need to understand the intricacies of the "Intermorphic Folder" or Local Device folder.

Note on iCloud Drive Subfolders (folders under the main app folder):

Our iOS apps support "flat" folders meaning they will display all files under the root folder, including files in any subfolders.

Tip: If you want to limit what files are displayed in the iOS app, you need to move the files you don't want to see out of the main app folder, perhaps into a "Archived" folder under iCloud Drive.

Apple iCloud Drive FAQ:

See: iCloud Drive FAQ

How to display iCloud Drive on your iOS device home screen:

See: Help using iCloud Drive

Tip: Why can't I see the relevant app folder in my Mac's iCloud Drive folder or in the iCloud Drive on icloud.com?

If you have just installed one of our iCloud Drive supporting apps for the first time, then it seems it can take a while for the iCloud Drive synching to happen and for the folders/files to appear on your Mac. We know not why.... but a couple of suggestions to try are:

  • Sign-in to your iCloud web account (icloud.com) and from the home page select the iCloud Drive icon when you will then be able to see all your iCloud Drive folders. It seems that doing this may cause the relevant app folder to appear soon on the Mac.
  • It may be that the relevent folder is not showing in the above iCloud Drive folder, in which case we have found that if you connect your device to iTunes on your Mac and then perform an iTunes "Sync" for that device, it seems the folders/files then appear straight away under your Mac's iCloud Drive folder and in icloud.com.
  • Audio

    Wotja is Audiobus / Inter-App Audio enabled which means you can send an audio stream out through that and then record it with another suitable 3rd party app that supports Audiobus / Inter-App Audio and recording.

    Audiobus / Inter-App Audio support is enabled by default and we make no charge for its use*.

    Inter-App Audio

    Please refer to the Apple website for information on how to use Inter-App Audio (and iOS 7+ system provided capability) with GarageBand. There are many other IAA enabled apps, such as Multitrck DAW and Thumbjam.


    Please refer to the Audiobus website for instructions on how to use Audiobus.

    *To use Audiobus you will also beed to install the Audiobus app for iPhone, iPad and iPod touch This is a 3rd party paid for app.


    Wotja is a very powerful MIDI application and supports Core MIDI and Virtual MIDI. You can record it with another suitable 3rd party app that supports Core MIDI / Virtual MIDI and MIDI recording.

    Wotja FREE: MIDI out and related settings are not supported.

    You might want to do this if iOS updates to a new version and you do not or are unwilling to do that or you have removed Wotja and the new version of Wotja is no longer available for your version of iOS (we use Apple tools to build our apps, and Apple updates to these tools change which versions of iOS we can build for). So, how do you restore the last version of Wotja available for your version of iOS?

    See Apple's instructions on how to do this or an AppleInsider article. Alternatively, you might try restoring from a device or even TimeMachine backup.

    We try as hard as we can to make our apps stable. To that end we now include in our apps either HockeyApp or Crashlytics. Because of this, rest assured we will have been alerted to it and we will be trying to fix it. This also means our latest versions are likely to be the most stable so we recommend keeping Wotja updated to the latest version, where your device/OS allows.

    Even though we (usually!) get the crash logs, it can also help us track things down if you send us any info about your particular crash, or indeed anything you think is not working right. The crash log files all start with the app name, and have an extension "crash". They can be found here: Where do I find Crash Logs?. They are text files that we can read, and give us useful information in tracking-down a crash and you can send them to us via our Contact Form. Don't forget to tell us what you were doing when you had the crash! Hopefully we will be able to fix the crash in the next update. Thank you!


    We will add items when required, otherwise see the Wotja FAQ.


    Sure! Follow these links to some tutorials that will help you to learn how to create sounds using the ISE:

    The most important thing to remember when you start using the ISE is that the audio for a voice ALWAYS comes from the rightmost signal-rate effect unit!

    The effects units for each voice are in general processed from left-to-right. Think of the system as a pipeline of audio information, where audio is generated over on the left, and passes through intervening effects units and ends-up on the right hand side, at which point it gets generated. However, the pipeline can actually be pretty complicated, in which case it can become useful to think of an Effect Module as being either like a tree of interrelated modules, or even a network of effect units working together in complex way!

    So, the best way of thinking how effects units work, is in terms of a collection of special-purpose units, that are connected together in pretty much any way you want, using invisible connecting "cables". The user interface shows these connections as best it can. Note that feedback loops or 'cyclic dependancies' between units are not allowed.

    The user interface displays a module by showing the signal-rate units at the top of the display area, and control-rate units below them. The currently selected unit is displayed differently to help remind you which unit you are currently editing.

    The outputs from all voice-level effect modules are summed-up by the ISE Synth, and are then passed into the Global Effects Module, which you can define if you want.

    Note that control-rate units do not generate stuff that you can hear directly, you use them purely to control parameters of other effect units in system. Control-rate units can be used to modulate parameters for both signal-rate and other control-rate units. For example, you could have an envelope unit (c/envlope) whose sole purpose is to create an envelope of values which is used to modulate the frequency parameters of a dsynth unit.

    You might be wondering at this stage, exactly why things are so flexible? Well, the reason is that it is this very flexibility which makes the ISE so powerful at creating a truly mind-boggling variety of exciting sounds and audio effects! However, this flexibility can also make things a little complicated to get your head around... which is where this documentation comes in.

    The ISE has a built in limiter which stops the sounds from overloading. However, it can sometimes add distortion in a mix with many instruments. The key to prevent this is to decrease the internal volume of the final mix. One way to do this is to make use of the global effects module level effects: you can simply use an amplifier to reduce the overall mix level! Another powerful technique is to apply a compressor to dynamically limit the volume level (though this can mask dynamics in some content).

    One easy way to deal with this is to make use of the global effects module level effects: simply use an amplifier to increase the overall mix level! Another powerful technique is to apply a compressor in "expander" mode, to dynamically boost the volume level (though this can mask dynamics in some content).

    This is very easy to do:

    1. Open the Modular Synth dialog
    2. Select the line you want, and click on the Edit button to pop-up the editor for the selected MIDI line.
    3. Click on Export, then OK to close the editor
    4. Select the line you want to copy to (and if in the Modular Synth dialog, set the Polyphony to whatever you want, probably the same as the line from which you are copying), then click Edit to pop-up the editor for the selected MIDI line
    5. Click on Import - your sounds are now copied and hopefully your piece will sound like you intended!

    You can of course also use exactly the same technique in the Effects dialog. You can copy Effects designs from MIDI line to MIDI line within the system; or copy the Global effects design to a MIDI Line, or copy from a MIDI Line Effects Design to the Global effect.
