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!

Hi! Many thanks for leaving a nice review and for purchasing the Pro version; cool! We are continually trying to improve Wotja and to make it easier to find your way around to do the things you want to do. If you have specific suggestions then please do send them in via our web contact form! Best wishes, Tim and Pete from Intermorphic.

Wotja is an (almost) superb tool to create generative music *or* just to use it as an endless music player for that matter just a couple of mouse clicks away. The developers (two brothers) are very responsive to questions and suggestions (multiple of my suggestions have been picked up by the team and implemented in newer versions!). The cons: the GUI and workflow could use some improvements and I miss the most obvious hotkeys but apart from that: excellent!

Hi De Kift, Many thanks for your kind review. We hope the improvements in Wotja 21.7.0 will be enough to persuade you to increase your rating to 5 stars! Plus, of course, Wotja Lite is Free to download and use - making it even better value than Photoshop :) Best wishes, Tim and Pete
