IME (drumming on an Ableton Push) latency around 20ms feels "instant" enough, and even ~80ms is manageable. and afaik that's mostly limited by the soundcard/drivers/cpu speed - you set a low audio buffer size and hope your PC can keep up :) i don't think USB latency really comes into it unless you've got a really garbage port/hub
