A waveform generating method is provided, which is capable of generating expressive musical tones. A plurality of partial waveforms are stored in a partial waveform memory. Property information on respective ones of the partial waveforms stored in the partial waveform memory is stored in a property information memory. The property information is retrieved according to inputted sounding control information in order to read out a partial waveform having property information corresponding to the sounding control information. The readout partial waveform is then processed according to the property information and the sounding control information to generate a waveform corresponding to the sounding control information.

Waveform generating method, performance data processing method, waveform selection apparatus, waveform data recording apparatus, and waveform data recording and reproducing apparatus

An electronic musical instrument is provided with a touch data generating device and a reverberation unit which generates a reverberation signal. The reverberation unit generates the signal correspond to the musical tone signal based on the touch data. The reverberation unit has a reverberation parameter forming device for forming a reverberation parameter which controls the reverberation signal based on the touch data. The parameter includes a delay period for a delay element and/or a coefficient for a multiplier. The musical instrument is allowed to add a mixing device to it, for mixing the musical tone signal and the reverberation signal. The musical instrument is also allowed to have a channel detecting device for detecting the number of instructed channels in place of the touch data generating device, thereby the reverberation signal being controlled by the number of the instructed channels.

Electronic musical instrument with reverberation effect

A musical tone generating apparatus generates a musical tone based on performance information generated by performing a keyboard and the like. The performance information functions to designate a first start timing of generating a musical tone signal and a second start timing of releasing a musical tone signal. Then, a period between first and second start timings is measured based on the performance information. Thus, one or more musical parameters of the musical tone is controlled in response to the measured period. Preferably, the musical parameter is the pitch, tone color, tone volume or musical effects such as portamento.

Musical tone generating apparatus employing control of musical

A soft pedal effect applying apparatus is utilized in an electronic musical instrument in order to apply a soft pedal effect to a musical tone to be generated when a soft pedal is operated, wherein this soft pedal effect is set quite similar to that of a non-electronic musical instrument such as a grand piano. Before operating the soft pedal, a generated musical tone has a reference tone volume and a reference tone color which are determined based on a touch operation intensity applied to a depressed key in a keyboard. By operating the soft pedal, a tone volume of the generated musical tone is softened due to the soft pedal effect by slightly lowering the tone volume by the predetermined tone volume attenuation value, wherein this lowered tone volume can be clearly discriminated from the reference tone volume. Such attenuation value can be arbitrarily varied in response to the tone volume level. In addition, a tone color of the generated musical tone is softened due to the soft pedal effect by giving a desirable filter characteristic to the tone color, wherein this softened tone color is different from the reference tone color. Thus, when the soft pedal is operated, the tone volume and the tone color of the generated musical tone are independently softened.
