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. 😑

Amazingly simple and fun music creation app!

What a fantastic way to create loops of melodies. And for just a small IAP, many different instruments are available. Just started out and have not yet tried recording or saving. But I am in awe of such a simple way to create melodies. Why portrait-mode only? Make it in landscape mode then it’s 5 stars!
