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.

2. An automatic performance device as recited in claim 1 wherein said automatic performance data generating section generates the note data of an automatic performance in accordance with the predetermined automatic performance pattern on the basis of predetermined note data, from among the note data generated by said note data generating section, which belong to a predetermined pitch.

3. An automatic performance device as recited in claim 1 which further comprises a tone signal generating section that generates tone signals of a same tone color on the basis of the note data generated by said note data generating section and the note data generated by said automatic performance data generating section.

4. An automatic performance device as recited in claim 1 which further comprises an output channel setting section that sets channel numbers to be imparted to the note data generated by said note data generating section and the note data generated by said automatic performance data generating section, respectively, and

wherein said output section outputs the note data generated by said note data generating section and the note data generated by said automatic performance data generating section after imparting to both of the note data respective channel identification data corresponding to the channel numbers set by said output channel setting section.

5. An automatic performance device comprising:

a note data generating section that generates note data on the basis of operation of a performance operator;

a note data input section that receives note data supplied from an external source;

an automatic performance data generating section that generates note data of an automatic performance in accordance with a predetermined automatic performance pattern on the basis of at least one of the note data generated by said note data generating section and the note data received via said note data input section; and

an output section that outputs the note data generated by said note data generating section and the note data generated by said automatic performance data generating section to outside said automatic performance device after imparting different channel identification data to both of the note data.

6. An automatic performance device as recited in claim 5 wherein said automatic performance data generating section generates the note data of an automatic performance in accordance with the predetermined automatic performance pattern, on the basis of at least one of note data, from among the note data generated by said note data generating section, which belongs to a predetermined pitch range and note data, from among the note data received via said note data input section, which belongs to the predetermined pitch range.

7. An automatic performance device as recited in claim 5 which further comprises an input channel setting section that sets a channel number for note data to be received via said note data input section, and

wherein the note data supplied from the external source has channel identification data imparted thereto, and said note data input section selectively receives note data, from among the note data supplied from the external source, which corresponds to the channel number set by said input channel setting section.

8. An automatic performance device comprising:
