Abstract
The automatic performance data programming instrument is constructed to program and record an object part of the automatic performance data by physically playing an input implement such as a keyboard. During the course of the programing operation, the automatic performance data is fed to a sound source for simultaneous tone generation. The volume information contained in the automatic performance data is selectively altered so as to intensify a tone volume of the object part relative to those of the remaining parts, in order to facilitate evaluation of the performance effect associated to the object part.
