Improve the Piano Roll
The piano roll is kind of a pain to build with. It’s “useable” when I just need to edit a not or two but it’s totally unenjoyable when I try to build a chord as the touch gestures are awkward and the UI just isn’t suited for it. FL Studios paino roll is one of the best ever and a great place to draw influence. It is so easy to build entire chord progressions and melodies with a mouse when a midi controller is an available.
