Title: Musical sound controller
Inventor: KONDO MASAO
IPC: G10H1/057
Filed: 2000-02-29
Abstract: PROBLEM TO BE SOLVED: To simulate the tone color of the damper of an acoustic piano and to make sounding control easier by providing ample capability to the sounding channels of a sound source. SOLUTION: When no empty channel exists in a sound source section during a key-off, no key-off sound is produced by the key-off. Release of normal key pressing sound is made longer than usual to make the release portion the replacement of the key-off sound. When the pedal is made ON while generating the key-off sound, the decay of the normal key pressing sound and the key-off sound is extended to replace damper-on additive sound. When no excess empty channel exists, the decay of either one of the normal key pressing sound or the key-off sound is extended in accordance with the time from a key-off to replace the damper-on adding sound. It is possible to use the key-off sound for the damper-on adding sound. Moreover, the damper-off sound may be used for the key-off sound.
