Abstract
Abstract A performance data editing apparatus is realized by a computer system and/or an electronic musical instrument to provide rich expressions of an automatic performance by performing a variety of editing processes on performance data. Herein, the performance data correspond to multiple parts of the music played by the automatic performance, so at least one of the parts is designated as an editing part. For example, a velocity expander editing process is provided to broaden a distribution range of velocity data representing tone volumes of musical tones of the editing part. Thus, it is possible to emphasize ups and downs in variations of the tone volumes with respect to the editing part. A sound duplication editing process is provided to duplicate generation of a same musical tone under a condition where a shortage of tone-generation channels does not occur. Thus, it is possible to produce a marrowy and thick musical tone with respect to the editing part. Further, a timing tuner editing process is provided to perform an adjustment such that playback timings of the musical tones of the editing part will substantially coincide with desired playback timings which are requested by a human operator.
