ABSTRACT:
Header control data for setting various characteristics of an automatic performance tone such as tone color, tone volume, tempo, effect and the like are stored in a header portion of a memory. The header control data are loaded into a buffer register, and various characteristics of an automatic performance tone to be generated are established on the basis of the header control data stored in the buffer register. In response to activation of a changing operator, the header control data in the buffer register are changed and a hence various characteristics of the automatic performance tone to be generated are changed. When the data in the buffer register is changed during an automatic performance, the header control data stored in the memory is changed in correspondence to the change. Therefore, during an automatic performance, various characteristics of the automatic performance tone can freely be changed while listening to the generated automatic performance tone, and also the header control data stored into the header portion of the memory can be automatically rewritten in correspondence to such change.
