ABSTRACT:
A calibration system for the keyboard of an electronic musical instrument. Compression of the key causes an output signal to be generated which varies in accordance with the amount of key depression. When the key is depressed to a nominally fully depressed position, the system stores an offset value relating to the difference between the actual output signal at this point and an expected reference output signal which would occur if the keyboard were perfectly adjusted from a mechanical standpoint. The offset value is stored in the memory and added to the key output signal during the normal operate mode of the instrument so that the output signal is adjusted in accordance with the offset value stored during the calibrate mode.
