Nearly a perfect music inspiration app.

So this app is nearly perfect as a creation tool. It’s quick, lightweight, inexpensive, fun, and helps loads to demystify a huge amount of theory gatekeeping. Sadly it does not support auv3 so you can’t use it as a midi controller for the near infinite iOS synths and samplers out there. This is my biggest request. It does support wired midi out which is nice, but if I’m using my iOS device I’m doing it for the sake of convenience and want to save my usb port for more important things like an interface or charging. My second request is if they created an omnichord like arpeggio strip to one side of the interface as melodies and bass lines could be created with the chord device. It wouldn’t clutter the interface and would make the entire experience dramatically more usable. Even without these additions, this is usually the first app I draw inspiration from if I’m looking for a randomized chord progression machine.
