Disappointed

Was expecting to get evolving SoundScapes. Instead, all the app seems to produce is variations on a theme.

Powerfull synth with an amazing design

This is quite a veteran app but it is still one of the most inspiring and contemporary synth in the IOS environnement. It has unusual features and a very unique approach. It is fun, versatile but with a lot of personality and it is extremly inspiring. GUI is superb and intuitive. Another very tasty synth by Erik Sight!

Nice Update and now AU!

Glad to see this go AU. Get all of this devs apps. They are excellent!

UPDATE 11/2018: The controls are somewhat cryptic but once you know what they do (as the on-screen hints indicate) you will find these are very cool apps.

This update makes this much more fun. Nice crazy sounds. Get it!
