摘要： An electronic musical instrument has pedals, such as a damper pedal and a sostenuto pedal, and controls a read out musical tone in consonance with the position of a depressed pedal, thereby to provide the same effects as those provided by half pedal playing with an acoustic piano. The electronic musical instrument includes: a detector for detecting the position of a pedal; a memory for storing tone data that is selectable in consonance with the pedal position; a reading circuit for selecting and reading the tone data from the memory in consonance with the pedal position detected by the detector; and a tone generator for generating a musical tone by employing the tone data that are read by the reading circuit.

摘要： The content of component waveforms of at least one signal is changed in a variety of ways among the formant center signals that are synthesized with the formant waveform signals, making it possible to arbitrarily change the waveform of a musical tone that is generated. To cope with changes in the formant waveform signals Ffj(t) or the formant carrier signals Gj(t) formed by synthesizing the component waveforms, furthermore, the signals Fj(t) and Gj(t) are weighed and interpolated. This permits the signals Fj(t) and Gj(t) to change smoothly. Moreover, the number or combination of formant waveform signals synthesized to produce a musical tone is controlled depending upon the musical factors, elapsed time of sounding, envelope levels, envelope phases and/or settings instructed by an operator. This enables the form of the synthesized formant to be changed and the content of a musical tone that is generated to he changed in a variety of ways.

摘要： An electronic sound generating device is proposed which can generate sound that is complex, profound and high in fidelity to acoustic sound. Sound of the acoustic instruments consists of a plurality of harmonics. Some of the harmonics have swings on their envelope curves, thereby causing beats of the sound. Inspired by this feature, the present invention causes swing on predetermined harmonics in synthesizing a plurality of harmonics for generating sound. A construction for swinging the envelope curves is also proposed.
