Love the app! As a bass player who also handles the keys with foot pedals, I had been limited with individual notes vs trying to program chords with more cumbersome programs. now I dont have to sacrifice the keys when i need to play the bass. I have two suggestions 1. Unless I have not figured out how, I need an option to play a muted chord/ no chord to turn off the sound of a sustained chord when there is no keys in the song. 2. I would love a way of changing the keyboard sound during the playback of the chords in different sections of the song Thanks!
