Use Wotja to: 1) Create custom live ambient generative music; 2) Generate ideas - MIDI notes/events, melodies, sound/audio; 3) Easily make beautiful 'keepsake' albums of mixes for sleep & relaxation; 4) Make cut-up text.

The stream of music and melodies that Wotja is able to generate can sound very organic and beautiful. The MIDI it generates can be played by a powerful integrated modular synth (Sound Engine) with support for 3rd party SoundFonts, or it can be used to drive 3rd party synths.

To help stimulate ideas and inspiration Wotja also includes a text cut-up engine, too - you might be surprised at how handy that can be for creative writing!

Users say of this powerful & unique creativity system: "hands down the best generative software that I have ever used", "Brilliant", "Extremely musical", "Deep and professional", "best MIDI composition tool", "Love Wotja!.

There's lots to explore, but you don't need to be a musician or expert to use Wotja, the evolution of Noatikl, Mixtikl, Liptikl & SSEYO Koan. Anyone inquisitive can learn to master its power; see our video tutorials.

What's New

Version 5.2.8

- In this update the 'Unlocked' In-App Subscription tier Music Play Time Timeout has been increased massively, from 1 hour to 8 hours (i.e. to the same value as was in the XT1 tier). Enjoy Wotja for longer and for less!
- The 6 month auto-renewing XT In-App Subscription tiers that were available to extend the Music Play Time Timeout for long play music requirements have now been removed from sale (see instead Long Play Music below). When an auto-renewing In-App Subscription is removed from sale it simply means that it can no longer be purchased and the pre-existing subscription will not auto-renew. An active XT In-App Subscription will therefore continue to work just as it does now until that subscription expires. At the time of subscription expiration should you wish to continue using Wotja without Free Mode Limitations then you can either subscribe to the 'Unlocked' tier or purchase the paid for annual version (Wotja 2018). If you have a requirement for very long play music (i.e. > 8 hours) then see below.
- Long Play Music: For those that need very long play times for their Wotja files (.wotja, .wotjabox), e.g. for installations, we have released a new app, 'Wotja X'. With its range of auto-renewing (but easy to cancel) weekly 'Long Play' In-App Subscription tiers 'Wotja X' allows its Music Play Time Timeout to be disabled whilst the tier is active. NB: It is easy to open your Wotja files in 'Wotja X' as both 'Wotja' and 'Wotja X' share the same iCloud folder. Tip: If you want to long play .noatikl and .mixtikl files then for the moment use 'Wotja' to add them to a Wotja playlist file (.wotjalist) and then export that to a .wotjabox file for playing in 'Wotja X'.
- Fixed issue with Albums/Playlists not sequencing correctly and mix countdown timer not updating.
- Randomization defaults in 'Settings' have been changed to better support automatic album creation on lower power devices (it is easy to change these to suit your purposes); Blank Cells setting now 35% and Tracks now 2.
- Fixed an issue when stopping a Mixdown Recording ('Unlocked' feature).
- Other minor bug fixes.

Allow in-app ad watching for ability to save once?


Paywall is draconian... save a single cell in a composition, not the whole thing for future access when you feel like risking $15 again (Not doing that after having my perfectly good Mixtikl 6 app get trashed). Like selling Mario the parts of a hammer before he can smash a single barrel. I guess I will keep my app open to keep this composition safe until I have $15 to burn.

Please look at a game like Sonny and you can see how ads can make it a two-way win for developer and uncommitted user.

Developer Response

As you acknowledge (thankyou!), we are continuing to put in a lot of effort to keep our apps evolving and current (not all devs do that). Wrt the $5-10 app(s) for iOS 8/9 that you purchased probably over 3 years ago, see the detailed explanation of what happened about 1 year ago when you updated your device to iOS 10: or We have invested a huge amount of blood, sweat and tears in consolidating all our apps into one to allow us to keep evolving and improving our apps and we simply cannot just make that work available for free, sorry. NB: You can always access earlier installed app releases from your Time Machine backups, and that is what Apple suggest (as they do not allow updates to me made available to apps no longer for sale). Please get in touch via our web support form if you wish. Best wishes. Tim and Pete.

IAA is very broken

Jon Mass

Seems like a cool app, but IAA doesn’t work with any hosts I’ve tried, lots of cuts and pops. iPad Pro 10.5, tried in AUM and Cubasis, a total mess in both, even after tweaking settings. May consider buying when this gets ironed out.

Developer Response

Hi Jon. Has the 5.0.4 release fixed this for you? Best wishes, Tim and Pete.

It's all finally coming together!


I'm giving this app a second chance and will eventually update my review of this new collective app by Intermorphic once I've spent more time with it. I enjoyed their previous app Mixtikl so I'm very interested to see how their earlier impressive efforts have evolved.

UPDATE: After having spent more time with this app, I have to say... it's come a long way since my experience with Mixtikl. In some ways, I liked the graphic user interface of Mixtikl better, but in practice, Intermorphic has made some efficient and intuitive choices. It somehow is much less of a complex puzzle to figure out, and now more of an excellent tool that allows you to get right to the business of crafting generative music.

The text to music feature is interesting and cool, but I'm barely scratching the surface with it so far.

All in all, I'd say Intermorphic did an excellent job taking several other mature generative applications, and melding them together with the best parts, in a fairly intuitive interface. Well done!

Developer Response

Hi Skip, thanks for your nice words. We hope you find that you grow to **love Wotja** which is where all our efforts are now going! A major new update should be out in a few days (V4.5). What we have done in that is something we would never have been able to do before. We won't spoil the nice surprise but we hope you like it :). Best wishes. UPDATE: Many thanks for your update Skip and glad to hear you are getting to grips with Wotja now. We hope you continue to enjoy it as we extend and improve it!
