Abstract
A foot pedal control system incorporated in an electrical musical keyboard instrument is expected to decide an output signal of a foot control pedal unit to be either analog or digital signal on the basis of a series of discrete voltage levels through periodical sampling on the output signal, and a microcomputer system of the foot pedal control system executes a program sequence for periodically monitoring the discrete voltage level, deciding the digital signal to be either analog or digital signal and determining an instruction of a player represented by the output signal.
