摘要： There is provided a musical tone control system which is capable of preventing control not intended by the user even when the user stops moving when controlling the generation of musical tones reflecting motion or physical posture of the user. A motion detecting device capable of being carried by an operator generates a detected motion signal corresponding to motion of the operator carrying the device, and transmits same to an external device. A musical tone generating device generates musical tones. A control device receives the detected motion signal transmitted from the motion detecting device and controls generation of musical tones from the musical tone generating device based on the received detected motion signal. The control device determines whether the operator is in a moving state based on the received detected motion signal, and when determining that the operator is not in the moving state, performs control to stop the generation of musical tones from the musical tone generating device after a predetermined time period elapses after the determination is made.

摘要： In a music system, an input unit is manipulated for inputting a signal representative of a performance operation amount rendered by a performer, and an output unit is provided for outputting a music sound in response to the signal fed from the input unit. The input unit has a grip part that is grasped by the performer and shaped to receive a dynamic pressure caused from grasping by the performer for inputting the performance operation amount. A conversion part is provided in the input unit for converting the dynamic pressure applied by the performer into a force acting in a specified direction. A detection part is positioned to align a sensitivity thereof with the specified direction for sensing the force generated by the conversion part and outputting the signal indicative of the performance operation amount in response to the sensed force.

摘要： An automatic performance control apparatus provides a hand controller which contains gyro sensors in X, Y directions. The gyro sensors are employed to accurately detect hand-swing motion applied to the hand controller without being affected by gravity. When the hand controller is swung by a human operator like a conductor's baton, angular velocity applied to the hand controller is detected based on detection values of the gyro sensors. The angular velocity becomes bottom at a change point of direction in a locus of the hand-swing motion of the hand controller; and a peak of the angular velocity appears between bottoms. So, peak detection process is performed on the angular velocity to determine a beat timing designated by the human operator. If the peak is detected, beat-timing detection data are automatically created and are transmitted to an electronic musical instrument having an automatic performance function. Based on the beat-timing detection data, the electronic musical instrument performs tempo control during progression of automatic performance in real time. Moreover, beat-number determination process is performed to make a decision as to which of beats in triple time corresponds to a current peak of the angular velocity. The tempo control of the automatic performance responds to a beat number determined, thus avoiding a deviation between beats of the automatic performance and beats designated by he human operator. Incidentally, it is possible to further provide acceleration sensors which cooperate with the gyro sensors to assist the peak detection.
