Strizbiz ,

Great update!

So glad to see this hasn’t been completely abandoned, I’ve been hoping this would become an audio unit for years, thanks! If I’m been completely honest I’m leaning towards the old design but it still sounds fantastic, great update.

Awesome App

I recently bought this app about 4 months ago and I was playing with the sounds and pressing on the keys, the synthesizer app sounded very good. I also love the demo on the pro sound bank! I recently made up a song on this app and it sounds fantastic harmony is awesome as well. I reccomend this app 100%!

Awesome app

I can't believe there's no other reviews here for this fantastic app. It's Audiobus compatible and has a pretty decent collection of synth sounds, an unbelievably nice package for iOS synth noodlers, and for 2 bucks! It's a crazy good deal...I've already used it with GarageBand and it worked and sounded great. Get this app now!
