I don't think you can have decent responsiveness without decent
physical feedback. there's a lot more involved than the ears in
playing an instrument. Breathing, posture, the amount of pressure that
goes into the string before it slides across the nail and which
direction it's released according to what you need to happen next with
it as well as whether or not the last knuckle is flexed at the

These things change whenever a different part, and therefore a
different sound, of the instrument is needed. That change is
consistant throughout the time the instrument is practiced with. It's
hard for me to believe that it's possible to do that without realtime
physical feedback tying the body to the ears. That's a helluva lot of
neural real estate being chucked out the window.
