<P>PROBLEM TO BE SOLVED: To disable a retrigger function when a plurality of keys are almost simultaneously released with an electronic musical instrument having pure tone priority functions for a plurality of key touches and the retrigger functions to the sequential key releases of the plurality of the keys. <P>SOLUTION: A retrigger discrimination section 24 causes the counting of a clock by a counter 25 to be started if there is the key under the key touch when the key release is detected. When the counter 25 counts up, a sound production control section 27 becomes effective to perform sound production for the key selected by a preference key selection section 28 among the keys under the key touches. Namely, even when the retrigger is set, the second sound production is prohibited before the lapse of the prescribed time such that the second sound production does not occur when the plurality of the key are almost simultaneously released. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
