Abstract
An automatic performance, such as an automatic arpeggio performance or a short-phrase sequence performance, is executed on the the basis of manual performance note data corresponding to key depression on a keyboard, and automatic performance note data are obtained from the automatic performance. The manual performance note data and automatic performance note data are output to an external device after both of the note data are imparted different MIDI channel messages, i.e., channel identification data. The manual performance note data and automatic performance note data can be used properly because they can be accurately distinguished from each other by the different channel identification data. For example, it is possible to avoid the inconvenience that a further automatic performance is executed on the basis of the automatic performance note data.
