I love the idea for this app. I think it's incredibly useful for non musicians, especially with the pitch to midi conversion via the mic. That being said, I personally hated the interface. Using a midi keyboard automatically moves one beat per note, there's no mass erase for a beat, and I want reverb for the drum sounds ala funklet. All that being said, this was a fun way to spend 30 minutes. Did some stevie wonder chords over some weirder rhythms https://goo.gl/kDCJPr
