I have some ideas but I don't know if it is good or not.
I am wondering if we can make the UI of music maker mod into a UI similar to Sky's for more convenience in real time playing.

In fact, many songs may frequently switch back and forth between two adjacent octave ranges, and the semitones of many songs are rarely used. Therefore, I think the existing UI is not that convenient for real-time music playing, while the keyboard layout of Sky games might be easier to play in real time, Especially in the social scene of multiplayer games. But I don’t know if you are interested in using this layout.
