Abstract:
1. A musical tone control device comprising: an input means for inputting a pitch parameter value corresponding to an operation of an operation terminal; a period signal generation means for generating a periodic signal; a modulation signal generation means for generating a modulation signal based on the pitch parameter value input by the input means and the periodic signal generated by the period signal generation means, the modulation signal for modulating a musical tone; an output means for outputting the modulation signal generated by the modulation signal generation means; a determination means for determining whether the pitch parameter value input by the input means is within a specified parameter range; and a control means for suppressing the periodic signal when the determination means determines that the pitch parameter value input by the input means is out of the specified parameter range, the control means for cancelling the suppressing of the periodic signal when the determination means determines that the pitch parameter value input by the input means is within the specified parameter range.
