TIMBRE CONTROLLER OF ELECTRIC MUSICAL INSTRUMENT

摘要

PROBLEM TO BE SOLVED: To obtain a timbre controller of an electronic musical instrument capable of easily simulating the changes of the desired timbres with a simple structure by controlling the sound volume of each frequency band of the respective timbres according to the characters of the respective timbres. ;SOLUTION: The sound volume of each timbre is controlled by a weighting table 23 and the tones of the respective timbres to be simultaneously produced are simultaneously controlled by a slide volume control 3a. When a player operates the slide volume control 3a, a control section 22 reads its set value and sends the value to an arithmetic section 21. The arithmetic section 21 subjects the weighting by each frequency band of the respective timbres read out of the weighting table 23 to the computation based on the set value of the slide volume control 3a and determines the correction values of the sound volume by each frequency band of the respective timbres. As a result, the sound volume value of each frequency band of the respective timbres is determined and the sound volume by each frequency band of the respective timbres between the playing is controlled by the sound volume control value.;COPYRIGHT: (C)1998,JPO
