Description

Detailed Description of the Invention The present invention provides automatic performance based on performance data input from a recording medium, actual performance (live performance), and automatic performance performed by recording and reproducing this live performance. The present invention relates to an electronic musical instrument with an automatic performance device that allows parts to be played in any combination.

Conventionally, performance data (for example, digital data containing pitch data, note length data, etc. of each note) corresponding to the musical score of a desired song is input from a recording medium such as a magnetic tape and stored in advance. An electronic musical instrument is known that is equipped with an automatic performance device that generates music and sequentially reads out the performance data to form musical tones. In this type of electronic musical instrument, during automatic performance, automatic performance of a desired part is sometimes prohibited, and only this part is actually played using a keyboard or the like to perform an ensemble performance (that is, a minus-one performance). Other conventional electronic musical instruments are equipped with an automatic performance device that records the actual performance using the upper keyboard or the like in the form of performance data, and also reproduces this data to reproduce the performance. . Even in such electronic musical instruments, there are cases in which a plurality of parts are actually played and recorded in advance, and then these parts are played back and other parts are actually played for an ensemble performance.

By the way, in one electronic musical instrument, there are two
It would be convenient to be able to perform various types of automatic performance selectively or in a desired combination for each part. It would be even more effective if the ensemble and the actual performance could be recorded and played back.

Therefore, the present invention provides automatic performance based on performance data inputted from a recording medium, actual performance, and automatic performance by recording and reproducing the actual performance using a single device.
Moreover, it is an object of the present invention to provide an electronic musical instrument with an automatic performance device that can be performed in arbitrary combinations for each part of a song.

The present invention is characterized by a 7th first memory device for storing first performance data input from a recording medium, a reading means for this memory device, and a second performance data created from an actual performance. A second memory device storing data and a read/write means for the memory device are provided, and
Based on the first performance data (inhibiting musical tone formation for each part of automatic performance), specifying operators for inhibiting musical tone formation for the number of parts and whether the actual performance is being recorded or played back. A recording/playback specifying operator is provided for the purpose of the present invention, and only for the part for which musical tone formation is prohibited by the musical tone formation prohibiting operator, recording and playback specified by the recording/playback specifying operator is performed. That's what I did.

An embodiment of the present invention will be described below as an electronic organ (electronic musical instrument).
