ABSTRACT:
An electronic musical instrument has a parameter setting system for setting a parameter necessary for controlling a musical characteristic which is a tone color or a musical effect such as a vibrato in a musical tone generating section. The parameter setting system comprises a memory (RAM) for storing a plurality of sets of parameters each set including, for example, a vibrato delay parameter and a vibrato speed parameter. When one of tone-color selection switches on a control panel is depressed, the set of parameters corresponding to the depressed tone-color selection switch are read and supplied to the musical tone generating section to thereby control the vibrato of the musical tone. The selected set of parameters in the RAM can be changed by the player through menu selection switches and data-up and data-down switches to desired values. The system may include a quit switch for restoring the set of parameters precedingly selected. The RAM may further store parameters for controlling another musical effect such as a tremolo. In this case, selection switches for selecting one of the vibrato and the tremolo are provided on the control panel, and parameters related to the selected musical effect are read from the RAM so that those parameters can be changed by the player.
