Abstract
A plurality of groups of tone parameters different in kind required for the generation of a musical sound is stored. The tone parameters of the same kind among those tone parameters are modulated with the same sway signal generated at the same time at a desired time or at fixed intervals of time when a key concerned is depressed. The modulated parameters are either restored in the original storage region or directly delivered to a sound source. The resulting musical sound has an acoustically natural comfortable tone quality. Even if musical sounds are generated simultaneously, no sways in the respective tones of the musical sound are canceled.
