Abstract
In an electronic musical instrument, first performance data stored in a memory, including a note data string, are read, and are supplied to a tone generator to obtain tone signals. The first performance data are transferred to an edit area in a RAM. A user performs a keyboard operation at a desired timing while listening to playback tones based on the output from the tone generator, thereby additionally writing corresponding second performance data for one tone in the edit area using time base data common to the first performance data. Non-edited note data and additionally written note data are distinguished from each other on the basis of tag data, and one of these two data is erased to continue an edit operation.
