Musical sound producing apparatus, recording medium and musical sound producing method

摘要

In the present invention, a click sound corresponding to key depression speed is generated, and the production timings of fundamental and harmonic components respectively corresponding to each footage are changed to vary from one another in accordance with a wait time, whereby the fundamental and the harmonic components to be synthesized by additive synthesis are changed to differ from one another. Next, a click sound corresponding to key release speed is generated, and the stop timings of the fundamental and harmonic components are changed to vary from one another in accordance with a wait time, whereby the fundamental and the harmonic components to be muted are changed to differ from one another. Accordingly, by the click sound being mixed with the drawbar sound having these slight tone changes, a unique drawbar sound such as that generated by the sound producing mechanism of an actual drawbar organ is generated.

主权项

1. A musical sound producing apparatus comprising:
a sound source which produces a fundamental and a plurality of harmonics of a musical sound; a sound production timing generating section which generates sound production timings of the fundamental and the plurality of harmonics to be produced by the sound source, based on a key depression operation; a sound production instructing section which instructs the sound source to produce the fundamental and the plurality of harmonics based on the sound production timings generated by the sound production timing generating section; a key release speed acquiring section which acquires a key release speed in response to a key release operation; a muting timing changing section which changes muting timings of the fundamental and the plurality of harmonics produced by the sound source, based on the key release speed acquired by the key release speed acquiring section; and a muting instructing section which instructs the sound source to mute the fundamental and the plurality of harmonics based on the muting timings changed by the muting timing changing section.
