About this app

Wotja is powerful & 'AI-free' system for Live Generative Music & MIDI. Use it to easily create & play on-device generated ambient music, soundscapes, textured drones, text-to-music melodies/arps + so much more…
• It's FREE, ad-free, updates are FREE & it can be used for FREE forever in Lite mode (Go Pro to do the max!)
• It's actively developed & delivers awesome results
• It's deep but also easy to use (wotja.com/tutorials)
• It's the *continued evolution* of 1990-02 SSEYO Koan (wotja.com/evo) which generated what became known as 'Generative Music'

Very cool, though somewhat intimidating. I'm impressed but the Pro version is priced too high for me and the Lite version is too restrictive. My only other complaint is that I don't understand why generative music would be licensed for personal use only. I can see why the software used would need to be credited, but the music itself should be usable as a Youtube soundtrack, for example. Just my two cents.

Hi Frank. Thanks for taking the time to leave a review! We recently decided to bring the price of the Pro version down a bit to $17.99 (should be live in a few days). That version allows *commercial use of recordings*. The Lite version is free & allows personal use of recordings, e.g. for your own non-commercialised YouTube videos. Hope that helps!

deep and powerful music tool... impressed, i bought a version for my phone and another for my laptop... but the UI is really strange, and i have to stumble over all kinds of cutesy automatic features i dont want, making the workflow tedious. im loving what im finally getting out of this... but it could be sooooo much smoother and intuitive! some kind of user forum would be very useful too!

Absolutely awesome! Online documentation is the best laid out documemtation I've ever seen making this new approach to music making easier to get the grasp of. I seem to have got the full version on play store now so that seems to be reolved. I will always use elements of generative in my music productios. Its not a different way to make music but a modern tool that can be incorporated and assist in all approaches to music production. Love u guys!
