Hmm. Sounds complicated 
So you have say run mode and edit mode, then while in edit mode you can also switch been two mode that are loopmode and anothermode?
Can you describe the modes and what each button does in each mode?
So like...
Button 1:
A short press In Loop mode it does 'A'
A long press In Loop mode it does 'B'
A short press In Edit mode it does 'C'
A long press In Edit mode it does 'D'
Button 2:
A short press In Loop mode it does 'E'
A long press In Loop mode it does 'F'
A short press In Edit mode it does 'G'
A long press In Edit mode it does 'H'
etc
