Dear SE, PLEASE have more control over keybinds for music performance.
It was already difficult enough to map the keys with your hand in a relaxed comfortable position onto notes with one octave range due to limits of characters such as "TAB/Shift, F-Keys, Symbols, keys on the numeric keypad, and such. Plus you can't have a keybind set to multiple keys for a single note (ex. Shift+Q, ALT+W.
Now with 3 octave ranges that opens opportunities to to play with 2 hands, further complicating matters worse. Don't get me wrong, the feature is very much appreciated, but if you are a musician you should know proper technique is a core aspect to your fundamentals which promotes and hones speed, accuracy, efficiency, consistency, etc.
I understand Shift/Ctrl/Alt are hard-assigned for +/- octave, but IMO it's not ideal. I don't think it should take much effort to remove or fix this so your other keybinds can have more versatility with customization.
