Wotja can be as simple as a visual and auditory experience that mixes written words and generative music. Wotja includes many pre-generated mixes and makes it easy for you to create random mixes with just a a couple touches.

Wotja can also be a very deep modular environment where you can edit every aspect of your music and sound parameters. The music engine is very adaptive with rules and settings that you can set for how each part plays. The sound engine is where you get your hands dirty building and editing your modular “synth” creations using sound/tone sources, FX units, controllers and routing junctions.

I don’t think I’ll ever get to explore all of Wotja’s features, but I do learn new things every day with the help of Intermorphic. Anytime I hit a wall, it gets knocked down pretty quick with explanations for those little things that aren’t readily apparent to me.

If you are brave enough to take the dive into Wotja’s vast generative and modular music environment, understand that you have a vast amount of control and there is probably a setting that you can tweak to make your creation sound just the way you want.

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,

Essential music app

This app is vital to my workflow and music creation. Whether I am using it’s generative midi capabilities or micro editing the onboard synths, Wotja has made making music with iOS so enjoyable and productive. I don’t know how I ever made music without it!
