I think this really ruined my ability to play music.

I tried to play with it a bit but really it's just awful to work with.

There isn't enough displayed keys on the UI to be of real use. It limits the ability to really even play a decent song or so.

Using shift keys for octaves is incredibly awkward. This UI could of been done way better if you just allowed players to hotkey buttons between normal octaves and higher or lower ones.

In example:

Normal octave:
Q,2,W,3,E,R,5,T,6,Y,7,U,I

Octave below or higher:
Z,S,X,E,C,V,F,V,G,B,H,N,M

Allowing to set keybinds for each individual octave would be a way better approach to use music.

Being limited just doesn't work out. It doesn't feel right or well, and I find it way harder to get a song done than ever before.

I think this UI totally needs to be redesigned for more keys or allow keybinding for EACH octave to really be efficient. Otherwise it's going to be too difficult to get anything done.
