Button Grid Help

Hi again,

Still very new and green here.

I want to have this Mechanical button grid:

  • Top right button toggles through 3 MIDI Channels, 1 (green) 2 (yellow) 3 (red). Kind of like a Song switch.

  • 3 other top buttons and 3 other farthest right buttons they act as sort of interdependent bank switches. All with 3 layers, green, yellow, red. Combining them will change the MIDI CC for the rest 9 buttons - row for row and column for column.

  • The 9 rest act as simple MIDI CC fire buttons.

I know this is maybe not the best description, but if someone could just point me in a direction of what I have to look into, or where to start or maybe a simile template out there - much appreciated!
