Abstract

Provided is an electronic musical instrument. The electrical musical instrument is configured to generate an internal acoustic signal; generate a sound generation instruction signal; output the sound generation instruction signal to an external sound source configured to generate an external acoustic signal; switch a first state in which the external acoustic signal is generated by the external sound source in response to the sound generation instruction signal, to a second state in which the internal acoustic signal is generated in response to the sound generation instruction signal; and, when the first state is switched to the second state, control the volume of the internal acoustic signal such that the state relating to the volume of sound generation based on the internal acoustic signal approaches the state relating to the volume of sound generation based on the external acoustic signal.

First claim

The invention claimed is:

1. An electronic musical instrument, comprising:
an internal sound source configured to generate an internal acoustic signal;
a generation means configured to generate a sound generation instruction signal;
an output means connected to an external sound source configured to generate an external acoustic signal, and configured to output the sound generation instruction signal to the external sound source;
a switching means configured to switch a first state in which the external acoustic signal is generated by the external sound source in response to the sound generation instruction signal to a second state in which the internal acoustic signal is generated by the internal sound source in response to the sound generation instruction signal;
a volume control means configured to, when the first state is switched to the second state, control a volume of the internal acoustic signal such that a state relating to a volume of sound generation based on the internal acoustic signal approaches a state relating to a volume of sound generation based on the external acoustic signal;
a first setting means configured to set a first value as a value of a parameter relating to the volume of the internal acoustic signal;
a second setting means configured to set a second value as a value of a parameter relating to the volume of the external acoustic signal; and
a first acquisition means configured to acquire the second value set by the second setting means,
wherein
when the first state is switched to the second state, the volume control means is configured to control the first value based on the acquired second value such that the state relating to the volume of sound generation based on the internal acoustic signal approaches the state relating to the volume of sound generation based on the external acoustic signal, and
the volume control means includes a correction means configured to, when the first state is switched to the second state, correct the set first value based on the acquired second value such that the state relating to the volume of sound generation based on the internal acoustic signal approaches the state relating to the volume of sound generation based on the external acoustic signal.

2. The electronic musical instrument according to claim 1 , further comprising:
a second acquisition means configured to acquire a correspondence relationship between the first value and the second value in a case where the state relating to the volume is equal for sound generation based on the internal acoustic signal and sound generation based on the external acoustic signal,
wherein when the first state is switched to the second state, the volume control means is configured to control the first value based on the acquired correspondence relationship and the acquired second value.

3. The electronic musical instrument according to claim 2 , wherein
the correspondence relationship is determined for each timbre, and
when the first state is switched to the second state, the volume control means is configured to adjust the first value based on a correspondence relationship corresponding to a timbre of the external acoustic signal among the acquired correspondence relationships, and based on the acquired second value.

4. The electronic musical instrument according to claim 2 , wherein
the electronic musical instrument includes a plurality of channels,
the first setting means is configured to set the first value for each of the plurality of channels,
the second setting means is configured to set the second value for each of the plurality of channels, and
when the first state is switched to the second state for one or more target channels among the plurality of channels, the volume control means is configured to control the first value corresponding to the target channel based on the acquired correspondence relationship and the acquired second value corresponding to the target channel.

5. The electronic musical instrument according to claim 1 , wherein
the first value indicates the volume or pan position of the internal acoustic signal, and
the second value indicates the volume or pan position of the external acoustic signal.

6. The electronic musical instrument according to claim 1 , further comprising:
a third setting means configured to set a plurality of regions determined based on a third value included in the sound generation instruction signal,
wherein
the external sound source is allocated to a first region among the set plurality of regions,
the first setting means is configured to set the first value of the internal acoustic signal for the first region,
the second setting means is configured to set the second value of the external acoustic signal for the first region,
the first acquisition means is configured to acquire the second value set for the first region, and
when the first state is switched to the second state for the first region, the volume control means is configured to control the first value for the first region based on the second value acquired for the first region.

7. The electronic musical instrument according to claim 1 , further comprising:
an input means configured to receive the external acoustic signal generated by the external sound source as a feedback acoustic signal; and
a detection means configured to detect a state of input of the feedback acoustic signal to the input means,
wherein the switching means is configured to switch the first state to the second state in response to a transition from a state in which input of the feedback acoustic signal to the input means is normal, to a state in which input of the feedback acoustic signal to the input means is not normal.

8. The electronic musical instrument according to claim 7 , wherein the switching means is configured to switch the second state to the first state in response to a transition from a state in which input of the feedback acoustic signal to the input means is not normal, to a state in which input of the feedback acoustic signal to the input means is normal.

9. An electronic musical instrument system, comprising:
the electronic musical instrument according to claim 1 ;
one or more external sound sources connected to the electronic musical instrument; and
a sound generation means configured to generate a sound based on the internal acoustic signal generated by the internal sound source of the electronic musical instrument and the external acoustic signal generated by the one or more external sound sources.

10. An electronic musical instrument, comprising:
an internal sound source configured to generate an internal acoustic signal;
a generation means configured to generate a sound generation instruction signal;
an output means connected to an external sound source configured to generate an external acoustic signal, and configured to output the sound generation instruction signal to the external sound source;
a switching means configured to switch a first state in which the external acoustic signal is generated by the external sound source in response to the sound generation instruction signal to a second state in which the internal acoustic signal is generated by the internal sound source in response to the sound generation instruction signal;
a volume control means configured to, when the first state is switched to the second state, control a volume of the internal acoustic signal such that a state relating to a volume of sound generation based on the internal acoustic signal approaches a state relating to a volume of sound generation based on the external acoustic signal;
