摘要： An electronic keyboard musical instrument comprising a multiplexed keyboard and a programmable microcomputer interfaced between the keyboard and a system of capture tone generators. The loading circuitry for the microcomputer, which is interposed between it and the keyboard multiplexer output, monitors the serial data stream and transmits only key change information to the microcomputer. If a keydown signal appears in a time slot where that time slot was previously empty, a multiple bit binary word identifying that time slot and indicating that it is a keydown condition is transmitted to the microcomputer. Similarly, if a keydown pulse disappears from a time slot when a pulse was previously present, a similar code is transmitted to the microcomputer indicating that the key is no longer depressed. The microcomputer controls the assignment and deassignment of tone generators for the accompaniment, solo and pedal manuals based on the key change information transmitted to it.

摘要： A system for automatically generating an accompaniment note pattern and a bass pattern programmed therein by the player. The system includes a programmable microprocessor wherein two patterns, one sounding in the frequency range of the solo and accompaniment manuals and the other in the frequency range of the pedals, can be programmed into a programmable and reprogrammable memory by the player by means of a separate keypad or one or two octaves of keys on the regular keyboards. The patterns are programmed in without regard to key, and on playback, the microprocessor is responsive to the chord being played at that time on the accompaniment manual to transpose the read out patterns to a compatible key. Means are provided for phase locking simultaneously occurring notes of the two patterns if they are of the same or octavely related frequencies. This is accomplished by causing both notes to be taken off the same divider string if a match of pitch occurs.
