Abstract
A percussion instrument data generating system can include a plurality of capacitance sensors coupled to the at least a first surface. A controller section can includes a plurality of switches for selectively connecting each capacitance sensor to a sense node. A capacitance sense circuit can be coupled to the common sense node and can measures a capacitance presented at the common sense node. An encoder section that generates a position value for a sensed input event based that varies according to which capacitance sensor detects the input event.
