US 5,478,967 A · Automatic performing system for repeating and performing an accompaniment pattern

Abstract

In an automatic performing system, when the track is changed to one having a different loop bar number, the bar to be reproduced next is easily determined by first dividing the number of bars accumulated from the start of accompaniment by the loop bar number stored in the sequence track. Based on the remainder resulting from the division, the number of beats is determined and the present pointer is set. In the automatic performing system, by comparing the data at the next address with the part designation data, it is determined whether the read out data belongs to the designated part or not. Therefore, the accompaniment data corresponding to the designated part data can be read out and reproduced.

Dependent claims

An automatic performing system comprising:

a performance data memory for storing a plurality of performance data loops having different numbers of bars in different said performance data loops;
a loop performer, coupled to said performance data memory, for repeatedly reading at least one of the plurality of performance data loops stored in the performance data memory and performing a musical performance based upon the data in said at least one of the plurality of performance data loops;
a bar number counter electronically coupled to said loop performer for accumulating the number of bars performed from a beginning of the performance of the loop performer;
means, coupled to said loop performer, for switching said loop performer to a new data loop during a performance;
and
a reproduction indicator, when switching to a new data loop during a performance of the loop performer, for dividing the number of bars accumulated by the bar number counter with the number of bars looped in the new data loop and indicating the bar in the new data loop to be reproduced by the loop performer based on the remainder resulting from the division;
wherein the number of bars in each said loop is the number two raised to a power, which is a whole number, and the bar to be reproduced in the new data loop is indicated by masking specified bits of the accumulated bar number indicated in binary form.
