Abstract
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.
