Are you suggesting that MSP should accept any type of music file.... like Sibelius (.sib) or Finale (.musx) (or Capella) or any of the many file types from other PC-based music applications that don't work on Android? .. And then be able to manipulate them?
IMHO, it seems you're trying to turn MSP Music Reader into an music notation program.
