I like medical tape for labelling controllers. so clean. that said, i can't wait till my crappy bitstream 3x breaks for good.
Usually i don't get around to labelling anyway because things change so much. By the time performance comes around, even that one lonely brain cell remembers which knob is which.
As for jumping controllers, i keep a blank/off layer in every set so i can set the knob (approximately) before the manipulating the live layer so it doesn't jump. At least, not too much to matter. That'll get you by.
