摘要： An electronic musical instrument capable of producing a performance effect resembling arpeggio. Tones corresponding to one or more depressed keys are sequentially produced from the lowest tone or the highest tone and an octave range in which tones are produced is shifted toward a higher octave or a lower octave at completion of each cycle of the tone production sequence. This shift of octave is continued to a certain predetermined octave and, after the tone production in the predetermined last octave has been completed, the tone production is repeated from the original octave or the tone production is conducted with the octave range being shifted in a reverse direction.For realizing simulation of arpeggio, plural key information produced by depressing a plurality of keys needs to be selected in a predetermined sequence. To this end, an up-down counter is employed in an example of the present invention. In a mode of arpeggio-like performance in which the tone pitch sequentially rises, for example, counting in the up-down counter is started from 0 for comparing contents of the counter with the key information and, when there is coincidence, the counting is suspended and the lowest tone is produced in response to the key information. After the lapse of a set time, the counting is resumed for repeating the comparison and a next higher tone is produced. The same operation is repeated until the counter overflows, when the octave is shifted to a next octave. The tone production is made at a predetermined time interval (a regular mode) or at a preset time interval from start of depression of the key (a random mode).

摘要： The musical tone generating apparatus converts a movement of a man into a musical tone. Such movement of the man includes a walking or running movement, a jumping movement, a rubbing movement and a beating movement, a turning movement and the like. More specifically, a tone pitch, a tone color, a tone volume or other parameters of the musical tone to be generated is controlled based on a value of a moving speed, a value of a jumping height or a value of frictional heat produced by the rubbing movement of player's hands.

摘要： A musical tone control apparatus controls a musical tone corresponding to a movement itself of an object and the like which is detected by a detector Such detector detects also a moving speed, a moving force, a moving angle or an intensity of given impulse of the object. In the case where the detector is mounted in the vicinity of a player's joint, the detector detects a revolving or bending angle of the player's joint. Hence, the musical tone can be controlled based on such angle of the player's joint. Thus, through this musical tone control apparatus, the player can generate a musical tone having, for example, a desirable tone pitch, a desirable volume and a desirable tone color based on the movement of the object or the player's joint.

摘要： An envelope generator is provided with a count circuit the count value of which is varied through addition or subtraction or combination thereof, and a conversion circuit which operates to convert the count value into amplitude data, so as to generate an envelope having a shape corresponding to variations with time of the count value. According to one aspect of the invention, the count circuit is a circuit which carries out computation for exponentially varying the count value through polygonal line approximation, so as to form an envelope of exponential characteristic. According to another aspect of the invention, the conversion circuit is a memory which has stored amplitude data corresponding to count values in advance so as to convert count values in the last linear region of the envelope obtained by the polygonal line approximation into amplitude data in exponential relation and to convert count values contained in the remaining polygonal line regions into amplitude data in linear relation.

摘要： An electronic musical instrument comprises an automatic rhythm performance device, an automatic bass chord performance device and an automatic arpeggio performance device. Each device has its own start-stop control circuit and a control in/out terminal. When a device is start-stop controlled, a control signal appears at the control in/out terminal, whereas if a control signal is externally applied to the control in/out terminal, the device is start-stop controlled. The control in/out terminals of the respective devices are connected together by a common line so that a start-stop of one device causes the start-stop of other devices.
