Full disclosure: I'm the dev. Let me know if you have any thoughts/suggestions :)<p>The app used to be a paid app that cost $20, but I decided to make it free for 45 days to open things up a bit. If you have an iPad and you like music, please try it out and play around.<p>Also, there's more detailed info about the app here (it was previously called Fiddlewax Pro).
