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.

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： An electronic musical instrument is of a time-shared digital processing type and capable of producing musical tones for a special performance. There are provided, at suitable time intervals, time periods in which no key code of a depressed key is produced by a key coder. During these time periods, a signal designating a special performance is generated. In a channel assignment circuit which assigns key codes of depressed keys to plural tone production channels there is provided a channel for an exclusive use for the special performance. A circuit for assigning data for the special performance transmits the data to the channel assignment circuit in response to the special performance designation signal from the key coder so that the data selected from among the key data already assigned to the tone production channels for ordinary performance are sequentially assigned to the channel allotted exclusively for the special performance. As an example of the special performance, description is made with respect to an automatic arpeggio performance in which tones are produced at designated orders of location from the lowest tone among the tones of the depressed keys.

摘要： An electronic musical instrument having a channel processor. The channel processor includes a tone production assignment circuit and an automatic arpeggio circuit. The tone production assignment circuit includes a key code memory circuit of a plurality of channels and an assignment control unit. A specific channel among the channels is used exclusively for the automatic arpeggio performance while the other channels are used for ordinary respective tone production corresponding to depressed keys by an ordinary key assignment operation responsive to depression of the keys. The automatic arpeggio circuit produces key codes one after another for the automatic arpeggio channel in accordance with the key codes already assigned to the respective ordinary channels and with arpeggio constituent orders in a sounding pattern. The arpeggio sounding pattern which is selected in response to a rhythm to be played contains binary data representing the arpeggio constituent orders. The arpeggio constituent orders herein mean the orders of the locations of the notes constituting the arpeggio alignment, the order being counted from the lowest one of the depressed keys in a predetermined keyboard range.

摘要： A tone production assignment circuit produces control information representing assigned key code, key-on etc. Such information has a large number of bits with respect to each channel. A multiplexing circuit has output lines the number of which is smaller than the bit number of the information and divides the information with a plurality of time slots with respect to one channel. The multiplexing circuit is controlled by a signal from a timing signal generation circuit. The multiplexing circuit is capable of rearranging information for transmitting information required for the respective individual channels and also capable of inserting a timing data in an available time slot. A multiple data analysis circuit decodes the information provided by the multiplexing circuit. Tone generators are provided for the respective channels and each one of them functions to latch only corresponding information among the decoded information by a latch circuit.
