ABSTRACT:
The present invention relates to a musical tone control apparatus which controls the generation of musical tone in response to the motion of player. By retaining holding means in a performer's hands and depressing finger pressure sensing means by a finger or fingers, signals are generated in response to the magnitude of finger pressure. When the operation signal generating means receives these signals, a pulse is generated therefrom. The beginning of the pulse is determined by associating the signals from the finger pressure sensing means with a predetermined first signal level. The ending of the pulse is determined by associating the signals from the finger pressure sending means with a predetermined second signal level, the predetermined second signal level being closer to a reference signal level which is set in releasing position than the predetermined first signal level. That is, the time interval of the pulse is determined by the characteristic of the hysteresis. Then, the musical tone control data generating means generates musical tone control data in response to the pulse. Thus, this musical tone control data is transmitted to a musical tone generating apparatus while a performer performs with vigorous movement.
