ability to remap qwerty synth keys (via xml?)
like instead of z,s,x,d,c being c, c#, d, d#, e
remapped to whatever you want, for example
z -> c
x -> d
c -> f
v -> g
b -> a
i think this would be really useful if you wanted to make a song and you wanted to impose a mode (like dorian, etc.) on it without having to play the keyboard like a piano. you could make the bottom row dorian and the top lydian or something.
it would also be useful for example if you wanted to make the qwerty input more like a violin or cello or sax fingering.
