It appears to me you've excluded some cognitive capabilities of musicians. Music is all about timing and anticipation. Let's say you have an instrument e.g. drums which actually emits its sound a little time/milliseconds after the hit. That doesn't stop you to perform accurately with a band, and only little adaption is required. I'm strongly looking forward 'World Music' gets redefined.
