Ratings and Reviews
Update to 1.1.1 broke this app
App was working just fine until the update to version 1.1.1 occurred. Now the app opens, but no audio is heard. Wish it didn't update itself to this broken version. Now it's just another app bought and paid for that needs to get deleted from my iPad. Sure wish developers would make sure their apps work before releasing updates that only break a previously working app. This was a lot of fun to play around with before this stupid update.
Update: after deleting the app and reinstalling it again all is well and working as before. Hooray now I can once again make those industrial sounds I have grown to love with this app.
Dope. Works well on iPad 2
Great way of making some interesting dark sounds. Great for inspiration! Going to use this in in combination with an Octatrack for sampling and looping.
I was a little worried about real time performance on an iPad 2 but it works well.

Barrel of monkeys=Vosis!
Loads of fun for anybody, though some users will be unfamiliar with some features, such as the ADSR Envelope. But just randomly messing with them is very entertaining. I imagine more interesting features are in the pipeline.
With Family Sharing set up, up to six family members can use this app.
