Abstract
A signal generation method implemented by a computer system includes: generating an audio signal in response to a manipulation of each of a first key and a second key; and controlling generation of the audio signal based on a reference point that is a position of the first key at a time point of a manipulation of the second key, based on the second key being manipulated during a manipulation of the first key.
Claims20
A signal generation method implemented by a computer system, the signal generation method comprising:
- generating an audio signal in response to a manipulation of each of a first key and a second key;
- and
- controlling generation of the audio signal based on a distance between an upper end position of the first key within a movable range and a reference point that is a position of the first key at a time point of a manipulation of the second key, based on the second key being manipulated during a manipulation of the first key,
- wherein the upper end position of the first key is a position in a state in which the first key is not manipulated.
A signal generation system comprising:
- at least one memory configured to store instructions;
- and
- at least one processor configured to implement the instructions to:
- generate an audio signal in response to a manipulation of each of a first key and a second key;
- and
- control generation of the audio signal based on a distance between an upper end position of the first key within a movable range and a reference point that is a position of the first key at a time point of a manipulation of the second key, based on the second key being manipulated during a manipulation of the first key,
- wherein the upper end position of the first key is a position in a state in which the first key is not manipulated.
An electronic musical instrument comprising:
- a first key;
- a second key;
- a detection system configured to detect a manipulation of each of the first and second keys;
- and
- a signal generation system,
- wherein the signal generation system includes:
- at least one memory configured to store instructions;
- and
- at least one processor configured to implement the instructions to:
- generate an audio signal in response to a manipulation of each of a first key and a second key;
- and
- control generation of the audio signal based on a distance between an upper end position of the first key within a movable range and a reference point that is a position of the first key at a time point of a manipulation of the second key, based on the second key being manipulated during a manipulation of the first key,
- wherein the upper end position of the first key is a position in a state in which the first key is not manipulated.
A non-transitory computer-readable recording medium storing a program executable by a computer system to execute a method comprising:
- generating an audio signal in response to a manipulation of each of a first key and a second key;
- and
- controlling generation of the audio signal based on a distance between an upper end position of the first key within a movable range and a reference point that is a position of the first key at a time point of a manipulation of the second key, based on the second key being manipulated during a manipulation of the first key,
- wherein the upper end position of the first key is a position in a state in which the first key is not manipulated.
