Patent ID: 7129406

Claim:
An automatic performance apparatus for reproducing automatic performance data which has a series of performance data assigned to any one channel of a plurality of channels, the series of performance data having identification data, representative of a performance part performed by performance data assigned to each channel, assigned to each of said channels, said automatic performance apparatus comprising: a reproduction condition specification portion for specifying a performance part to be excluded from a performance during the reproduction of performance data, or to be performed with any other performance part excluded from a performance during the reproduction of performance data and; a reproduction control portion for identifying a performance part to be performed by each performance data based on said identification data, and controlling reproduction and non-reproduction of each performance data in accordance with the reproduction condition specified by said reproduction condition specification portion, wherein said reproduction condition specification portion includes a mute state register for storing, on the basis of the specification of said performance part, mute data indicative of whether performance data is to be reproduced in corresponding relation to the performance part; and said reproduction control portion includes an identification data register for storing said identification data during reproducing said series of performance data; a first detector for referring to the identification data stored in said identification data register and detecting a performance part to be performed by each of said performance data by use of the channels assigned to each of said performance data; and a second detector for referring to mute data stored in said mute state register and detecting by use of said detected performance part whether each of said performance data is to be reproduced.
