Abstract
According to one aspect, there is an electronic musical instrument including operators which includes a first operator corresponding to a first pitch and a second operator corresponding to a second pitch, and a sound source configured to generate a first output signal from a first close loop and a second output signal from a second close loop, to generate an integration signal, and return a subtraction signal, the subtraction signal being obtained by subtracting a signal circulating through the first close loop from the integration signal, to the first close loop, and then output a musical sound signal including signal components corresponding to the second pitch as a musical sound signal corresponding to the first pitch.
Claims13
An electronic musical instrument comprising:
- a plurality of operators which includes a first operator corresponding to a first pitch and a second operator corresponding to a second pitch;
- and
- a sound source,
- wherein the sound source is configured to:
- generate, in response to designation of the first operator and the second operator, a first output signal from a first close loop corresponding to the first pitch and a second output signal from a second close loop corresponding to the second pitch;
- generate an integration signal by integrating the first output signal and the second output signal;
- subtract a signal circulating through the first close loop from the integration signal to obtain a subtraction signal;
- and
- return the subtraction signal to the first close loop, and then output a musical sound signal including signal component corresponding to the second pitch as a musical sound signal corresponding to the first pitch.
A method comprising:
- generating, in response to designation of a first operator and a second operator, a first output signal from a first close loop corresponding to a first pitch and a second output signal from a second close loop corresponding to a second pitch;
- generating an integration signal by integrating the first output signal and the second output signal;
- subtracting a signal circulating through the first close loop from the integration signal to obtain a subtraction signal;
- and
- returning the subtraction signal to the first close loop, and then outputting a musical sound signal including signal components corresponding to the second pitch as a musical sound signal corresponding to the first pitch.
A non-transitory computer-readable storage medium having a program stored thereon which controls a computer of an electronic musical instrument to perform functions comprising:
- causing an electronic musical instrument to:
- generate, in response to designation of a first operator and a second operator, a first output signal from a first close loop corresponding to a first pitch and a second output signal from a second close loop corresponding to a second pitch,
- generate an integration signal by integrating the first output signal and the second output signal;
- subtract a signal circulating through the first close loop from the integration signal to obtain a subtraction signal;
- and
- return the subtraction signal to the first close loop, and then output a musical sound signal including signal components corresponding to the second pitch as a musical sound signal corresponding to the first pitch.
