Absolute must buy for music creation on the iPhone & iPad.

Heres the important part...
One of the best instruments on the app store. I absolutely LOVE this app. You will too no matter what device you use.
In my opinion, a tie for the best controller on iOS. The other being SoundPrizm Pro.
This is without a doubt the most expressive app for doing leads. I used this app to control sounds in SynthMaster to do Pink Floyd leads from the Wish You Were Here album. Just amazing.

Five star all the way.
