发明名称 ELECTRONIC MUSICAL INSTRUMENTS
摘要 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.
