Love creating music or writing? Use Wotja to make your own ambient generative & reflective music, MIDI and 'text-to-music' melodies & music ideas. Generate 'cut-up' text for creative writing, too.

"Masterpiece", "the best generative software that I have ever used", "Brilliant", "Extremely musical", "Deep and professional", "best MIDI composition tool", "Love Wotja!".

Wotja is the evolution of SSEYO Koan, Noatikl, Mixtikl, Liptikl & Tiklbox. It uses generative techniques we've been crafting for nearly 30 years.

As you'd expect of a generative system with such a long history of continuous development, it is deep, unique & powerful. However, you don't need to be a musician or expert to use it. Anyone inquisitive can learn to master its power; see our video tutorials.

'Wotja A' is the accessibility version of Wotja and has support for VoiceOver.

Yes, an 'annual' version is also available.

Steep learning curve...


but worth the exploration! Generative music can mean a lot of things and Wotja covers all of them. You can use sounds provided in the many and varied paks or you can send midi to your other apps and equipment.

The modular synth and the pattern coding aren’t readily intuitive to knob tweeters, but you can obtains some really cool results if you take the time to explore!

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.

Best generative music app


Its sad to see many bad comments in such a great apps.

I wanna give my inside so new buyers don't get turned off of such amazing apps.

First off, you can buy the full version without subscription.

I mostly use noatikl, it has great sound possibilities but i use it to sequence external synths, 16 midi outputs can be used to sequence anything inside and of outside the ipad.
There is a learning curve but with any app as complex as this its understandable. There is so many possibilities on this app.
Their website has lots of information and a very helpful forum.
The creators are super nice people, theres only 2 of them but they do answer very quickly and are not greedy like other reviewers mention.

It really scares me to think that the developers would stop supporting and growing such amazing tools, please don't!

Much love

Developer Response

Thank you so much for your positive review. We work very hard to create our niche tools so your kind words are much appreciated! It is always much harder to build something unique and special than to destroy it. Our deep, powerful tools are a labour of love more than anything else so we can only think that the people who leave bad reviews, especially for something that is free, simply do not understand how much time, care and love we put into them and just how little return there is from doing that. We know that our tools are not in any way perfect but we have always been in it for the long haul. You can know that your love (and love from others like you) will help Wotja get better and better over time. Thank you so much for your support and encouragement!
