Abstract
A music apparatus processes a number of waveforms designated by performance information to concurrently generate the designated number of voices. In the music apparatus, an input section can provide the performance information in repeatable sessions. A computing section can compute a limited number of the waveforms in one session when the performance information is provided by the input section. A memory section memorizes the waveforms computed by the computing section. A controlling section operates in a first session if the designated number exceeds the limited number for controlling the computing section to skip computation of a remaining number of the waveforms while the computed waveforms are memorized in the memory section, and further operates in a second session for controlling the computing section to compute the remaining number of the waveforms. An output section can be enabled to concurrently generate the voices based on the designated number of the waveforms which are partly computed and memorized in the first session and partly computed in the second session.
