摘要： A manual vibrato control device, system and processing arrangement are disclosed. A manual vibrato includes a rotatable shaft, a raised cam section on the shaft, first and second biased collars received on the shaft either side of the cam section, the bias of the first collar being rotationally opposite to the bias of the second collar such that as the shaft rotates in one direction, it receives a return force from the first collar but does not rotate the second collar, and vice versa.Also disclosed are processing techniques to take the rotational data from rotational sensors, preferably Hall Effect, on the shaft and generate pitch change instructions for a pitch modification device. The mapping is user controllable to produce desired effects and performance.
