Patent ID: 7820902

Claim:
A music performance system for a music performance on plural musical instruments, comprising: a master musical instrument including plural manipulators selectively moved for specifying tones to be produced, a converter monitoring said plural manipulators and producing detecting signals representative of physical quantity expressing movements of said plural manipulators, an information processing system connected to said converter and producing pieces of performance data expressing a performance on said plural manipulators on the basis of said physical quantity, and a communication system connected between said information processing system and a communication channel for transmitting said pieces of performance data through said communication channel; a slave musical instrument including another communication system connected to said communication channel and receiving said pieces of performance data from said communication system, other manipulators for specifying tones to be produced, plural actuators provided for said other manipulators and selectively energized with driving signals so as to give rise to movements of said other manipulators on trajectories, a mechanical tone generating system connected to said other manipulators and producing acoustic tones when said other manipulators strongly actuate said mechanical tone generating system, and a controlling system connected to said another communication system and said plural actuators and selectively supplying said driving signals produced on the basis of said pieces of performance data to said plural actuators so as selectively to move said other manipulators on said trajectories; and a delay canceller provided in association with said information processing system so as to reduce a time lag between the transmission of said pieces of performance data and the generation of said acoustic tones, wherein said delay canceller has a pre-estimator provided in association with said information processing system and presuming said physical quantity at a time later than the present time by at least part of said delay time so as to make said pieces of performance data contain pieces of motion data expressing the presumed physical quantity, and a controller provided in association with said controlling system and causing said plural actuators to force said other manipulators to have said presumed physical quantity, whereby said other manipulators strongly actuate said mechanical tone generating system for producing said acoustic tones.
