Claims

[Claims for Utility Model Registration] (1) A pitch control device for an electronic musical instrument capable of controlling a sound source in response to a performance control input from a performance control input device and generating multiple systems of musical tones from the sound source, mode switching means; system-specific portamento setting means for setting portamento data for each of the systems so that when the first mode is selected by the mode switching means, an independent portamento is applied to each of the systems; and a common portamento setting means for collectively setting common portamento data so that a common portamento is applied to the plurality of systems when the second mode is selected by the mode switching means. Features a pitch control device for electronic musical instruments. (2) A pitch control device for an electronic musical instrument according to claim 1, wherein the mode switching means is means for selecting an instrument performance mode according to a different performance method for the performance control input device. (3) In a pitch control device for an electronic musical instrument that can control a sound source in response to performance control input from a performance control input device and generate multiple systems of musical tones from the sound source, portamento data is generated for each system. system-specific portamento setting means for setting; mode specifying means for selectively specifying a common portamento control mode; and when the common portamento control mode is not specified by the mode specifying means, the system-specific portamento setting means Portamento is added to musical tones of the corresponding system according to separately set portamento data, and when the common portamento control mode is specified by the mode specifying means, the portamento control mode set by the system-specific portamento setting means is added. Portamento adding means for adding portamento to musical tones of all systems to which portamento should be added according to portamento data set for any one system among the portamento data; Pitch control device for electronic musical instruments. (4) In the control device for an electronic musical instrument according to claim 3, the mode specifying means selects the portamento data set for any system among the portamento data set by the system-specific portamento setting means. 1. A pitch control device for an electronic musical instrument, comprising means for selecting whether to perform common portamento control using additional means.
