ABSTRACT:
A musical tone control apparatus detects a bending angle of a player's joint portion such as a player's elbow joint portion, so that a musical tone control parameter such as a tone pitch of a musical tone to be generated is controlled based on the detected bending angle. In advance, the whole angle area ranging from the fully-bent-angle to the fully-stretched-angle at the player's joint portion is divided into several angle areas. Then, the present bending angle is picked up when a key-on switch is operated. If the present bending angle is increased as compared to the preceding bending angle, certain bending angle which is obtained by increasing the present bending angle is set as a future bending angle. If not, another bending angle which is obtained by decreasing the present bending angle is set as another future bending angle. In accordance with one of the angle areas to which the future bending angle will belong, musical tone control data is generated. Based on such musical tone control data, the parameter of the musical tone to be generated is controlled.
