Hi, Peavey made a bass that had frets that were split, and wired, that did figure the pitch by knowing what fret and string was being play. It also had a separate pick-up for each string to measure velocity, and a floating bridge that could tell if you were bending a string and would send pitch bend data.. There was (and is) latency because of the velocity pick-up, but it stayed at a constant 30 ms. RG
