First Claim
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.

Abstract
Various embodiments of the present invention are directed to providing a musical tone control device for carrying out appropriate control in user-performed operations. A pitch parameter value PB set by a pitch bend wheel may be loaded and a determination may be made whether the pitch parameter value PB is within a specified range. If the pitch parameter value PB is within the specified range, a time t may advance by 1, and a determination may be made whether the time t has reached t1. If the time t has reached t1, an amplitude value from a low frequency oscillator (LFO) table corresponding to the time t may be read out from the LFO table. The vibrato value VI may be calculated by multiplying the amplitude value and the vibrato depth. The pitch parameter value PB and the vibrato value VI may be added and transmitted to the sound source.
