Abstract
The present invention provides a system for communicating data among microprocessors which are utilized to control an electronic musical instrument. A master microprocessor transmits a synchronizing signal comprising two, spaced pulses to the other microprocessors causing the other microprocessors to interrupt their operations and become synchronized with the synchronizing signal. Thereafter, according to a prearranged sequence, one microprocessor commences transmitting data while simultaneously the other microprocessors commence inputting data.
