Superb package for ambient music creation

Wotja a complete package for the creation of ambient, generative music. Offering complete and comprehensive control of all parameters, it makes possible gorgeous, ambient music. As someone who has been creating this kind of music for a while, Wotja enables me to achieve my vision in ways no other software can. The monthly subscription model is a total steal; if you need support, it’s fast, technically sophisticated, and patient. The latter is important as I think I have asked every dumb question I can about the software. The support people are unfailingly friendly and very helpful. If you have the ambient gene, this package is for you,

Fantastic support from Tim & Pete

I had a very serious issue with Wotja X that made things completely unusable. They worked tirelessly to fix the issues I was experiencing and got everything fixed.

Wotja is a fantastic generative sound canvas that you can control - or just listen to. It can be as easy as loading one of many included mix albums, to the generation of random mixes, to manual mix editing to actually getting dirty under the hood with the voice editing and the instrument design. It goes pretty deep!
