Abstract
An electronic musical instrument according to one embodiment includes playing operators specifying respective pitches, and at least one processor which is configured to execute processing of acquiring string sound data including a fundamental sound component and a harmonic tone component corresponding to a specified pitch, acquiring stroke sound waveform data that does not include the fundamental sound component and the harmonic tone component corresponding to the specified pitch but includes components other than the fundamental sound component and the harmonic tone component, and synthesizing the string sound data and stroke sound data corresponding to the stroke sound waveform data at a set ratio.
Claims14
An electronic musical instrument comprising:
- a plurality of playing operators specifying respective pitches and velocities;
- and
- at least one processor,
- wherein the at least one processor is configured to execute processing of:
- acquiring window-multiplied waveform data corresponding to a specified pitch and a specified velocity;
- acquiring string sound data including both a fundamental sound component and a harmonic tone component based on the window-multiplied waveform data;
- acquiring stroke sound data that does not include the fundamental sound component nor the harmonic tone component corresponding to the specified pitch but includes components other than both the fundamental sound component and the harmonic tone component;
- and
- synthesizing the string sound data and stroke sound data at a set ratio.
An electronic keyboard musical instrument comprising:
- a keyboard specifying respective pitches and velocities;
- a tone selection operator;
- and
- at least one processor,
- wherein the at least one processor is configured to execute processing of:
- acquiring window-multiplied waveform data corresponding to a specified pitch and a specified velocity;
- acquiring string sound data including both a fundamental sound component and a harmonic tone component based on the window-multiplied waveform data;
- acquiring stroke sound data that does not include the fundamental sound component nor the harmonic tone component corresponding to the specified pitch but includes components other than both the fundamental sound component and the harmonic tone component;
- and
- synthesizing the string sound data and stroke sound data at a set ratio according to an operation of the tone selection operator.
A method of generating musical sound comprising,
- executing, by at least one processor of an electronic musical instrument, processing of:
- acquiring window-multiplied waveform data corresponding to a specified pitch and a specified velocity;
- acquiring string sound data including both a fundamental sound component and a harmonic tone component based on the window-multiplied waveform data;
- acquiring stroke sound data that does not include the fundamental sound component nor the harmonic tone component corresponding to the specified pitch but includes components other than both the fundamental sound component and the harmonic tone component;
- and
- synthesizing the string sound data and stroke sound data at a set ratio.
