Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic musical instrument having an output terminal for outputting performance data.

[0002]

2. Description of the Related Art Conventionally, there is known an electronic musical instrument configured to output performance data to the outside for the purpose of storing (recording) the performance data in a sequencer and controlling pronunciation of an external sound source based on the performance data. Has been. Here, a case where a synthesizer is taken as an example of an electronic musical instrument having such a configuration and a sequencer and an external sound source are connected to the synthesizer will be described.

When a synthesizer, a sequencer, and an external tone generator are combined, the performance data generated by the performance using the synthesizer is stored in the sequencer, or the performance data generated by the performance using the synthesizer, or from the sequencer. The read performance data is transmitted to an external sound source to control the sound generation of the external sound source to generate a musical sound. The synthesizer itself is also usually provided with a built-in sound source, and the performance data generated by the performance using the synthesizer or the performance data read from the sequencer may be sent to the built-in sound source to control the sound generation of the built-in sound source.

[0004]

Thus, for example, when a synthesizer, a sequencer, and an external tone generator are combined, even when the synthesizer sends performance data to the external tone generator to control the tone generation of this external tone generator. It is necessary to configure the performance data so that the performance data can be recorded in the sequencer. Therefore, the performance data output from the synthesizer is supplied to the external sound source via the sequencer. In this case, in the sequencer, a predetermined program is started in response to the input of the performance data, the program performs a recording process as needed, and the input performance data is output to an external sound source. . Outputting the performance data input in this way through a program is called soft through.

In this case, when performance data is sent from the synthesizer to the internal tone generator and the performance data is also sent to the sequencer for recording, the performance data is not output to the external tone generator and the sound is not controlled. It is necessary to turn off the soft through, and on the other hand, when controlling the pronunciation of an external sound source, it is necessary to turn off the signal of the performance data to the built-in sound source and turn on the soft through of the sequencer.

In this case, on / off of transmission of performance data to the built-in sound source built in the synthesizer is operated on the synthesizer side, and on / off of soft through of the synthesizer is operated on the sequencer side. Conventionally, there has been a problem that two operations are required when switching the sound source in this way, and the operations are complicated. It is an object of the present invention to solve this problem and to simplify the operation of soft-thru switching in an electronic musical instrument having a function of outputting performance data.

[0007]

The first electronic musical instrument of the present invention which achieves the above object comprises: (1) an output terminal for outputting performance data; (2) a soft through for transmitting received performance data to the outside. Selecting means for selecting ON / OFF of the soft through function of a device having a function (3) means for outputting a control signal for controlling ON / OFF of the soft through function according to selection by the selecting means To do.

Further, the second electronic musical instrument of the present invention which achieves the above object, is (4) a controller having a performance operator, and (5) generates a musical sound based on performance data corresponding to the operation of the performance operator. Sound source (6) Output terminal for outputting performance data (7) Selection means for selecting whether or not to use the sound source (8) Software for transmitting received performance data to the outside according to selection by the selection means It is characterized by comprising means for outputting a control signal for controlling on / off of the soft through function of a device having a through function.

In the electronic musical instrument of the present invention, the device of the above (2) or (8) may be housed in the same housing integrally with the electronic musical instrument of the present invention, or The electronic musical instrument of the present invention is housed in a housing different from that of the electronic musical instrument.
It may be connected by a communication cable conforming to the DI standard. Further, the means for outputting the control signal in the above (3) or (8) may be those which output via the output terminal in the above (1) or (6), respectively, or The control signal may be output separately from the output terminal.

[0010]

According to the first electronic musical instrument of the present invention, the first electronic musical instrument side is provided with a selection means for turning on / off the soft through function, for example, a changeover switch. Since a control signal for controlling on / off is output, for example, even when the first electronic musical instrument is provided with a sound source, switching of the sound source and on / off of the soft through function can be performed by the operation of the first electronic musical instrument side. Only the operation is completed and the operation is simplified.

A second electronic musical instrument of the present invention is provided with a sound source and means for selecting whether or not to use the sound source, for example, a changeover switch for the electronic musical instrument, and a soft through function is provided according to the selection by the selecting means. Since it outputs a control signal that controls the on / off of, when switching the sound source,
The operator does not need to be aware of the on / off operation of the soft-through function, only the switching of the sound source, and the complexity of the operation can be further avoided.
