JPS5611674A - Automatic playing unit for piano - Google Patents

Abstract

PURPOSE: To obtain excellent reproduced output, by recording the music played in matching with synchronizing signal visually and audibly by the player and reproducing the playing information in matching with the timing signal picked up from the recorded information.

CONSTITUTION: The case is that the playing information is recorded in the automatic playing unit PN. The timing signal in different frequencies is produced from the variable period timing signal generator VCK, and one is given to the data recorder DR as the synchronizing command via the keyboard scan timing generating section. Another is input to the tempo expression section TDS via the tempo expression control section TC and the tempo is expressed audibly at TDS and the recording played by the player in matching with this tempo is recorded. Next, the reproducing operation is shown. The timing signal is detected from another circuit (simultaneous timing generator SCK and timing controller section PCT) from the said recorded data DT, and the reproduced output is generated from the playing section PO while giving synchronism to the playing information from the said DT.
