Concept is great, execution is poor

This app exposes some very interesting concepts surrounding music.

Unfortunately, this app is unpolished and is more like a crude demonstration of an idea for an application. 👎🏻

Thank you for your feedback!

Pretty cool little music maker! Only thing that would make it better would be if maybe add layers so you can play different pieces at the same time

Updated: Now With MIDI! Heck yeah.

Looking forward to using this in my compositions - cool interface, some surprises in the melodies too.


Fun to play with, could have a little more utility for composers.

In a nutshell - needs some kind of useful export capability beyond just a visual score. MIDI would be ideal, Music XML would even work... even audio (although not as ideal).

Can't rationalize keeping it on my 16gb phone without any of that though. 😑
