I like the ability to play different instruments, but the restricted on keybinds is too strict.
I cant bind F1-F12 keys, (which were my primary keys for playing)
Also some notes, such as Bb, I used keys
[, ], \ for, the +1 and -1, however it is now restricted to a single key for the normal note, with shift/control being the only possible modifiers to get +1 and -1

Please let me keybind any key to any button / modifier of any combination I choose.
