Abstract
An automatic performing apparatus of an electronic musical instrument arranged to produce musical tones in response to musical performance data read out of an external storage such as a musical sheet. The external storage stores the musical performance data and control data to control generation mode of musical tone signals to be produced. In the apparatus, musical performance data and control data are stored in separate memories. In order for a player to change the generation mode of musical tone signals intentionally, a plurality of panel switches are associated with a control data memory so that the control data for tone generation mode can be rewritten by operation of any one of panel switches.
