WAVE-FORM GENERATOR

PROBLEM TO BE SOLVED: To prevent a regenerated sound from being monotone or artificial even when regenerating time becomes longer, by providing a fluctuation adding means which adds fluctuation to a regenerated wave which is produced by a wave-form regenerating means when variation set by a position-information generating means becomes smaller than a prescribed value. SOLUTION: A wave-form memory 12 consists of RAM which stores wave- form data to be regenerated, and a digital signal processor(DSP) 8 regenerates wave-form data in the wave-form memory 12 using digital process. A CPU 22 performs general controlling such as controlling of the DSP 8, or condition measurement and processing of an operant group 20 or a keyboard 30. When variation set by a position-information generating means becomes smaller than a prescribed value, a fluctuation adding means adds fluctuation to a regenerated wave which is produced by a wave-form regenerating means. Because repetitive regeneration of the same wave-form adds fluctuation such as vibrate to the generated wave-form, sound having natural regenerated wave-form is produced.
