Claims

[Claims for Utility Model Registration] Portamento time specifying means for specifying portamento time, performance controls, key information input means, normal key assigner means for executing normal key assignments, and portamento key assignments. and a portamento key assigner means for performing frequency control for portamento on the pronunciation channel assigned by the portamento key assigner means.
An electronic musical instrument comprising: a frequency control means;
time change data generation means; portamento time change means for changing the portamento time specified by the portamento time specification means with portamento time change data generated by the portamento time change data generation means; and the key information. When key press information is input from the input means, the portamento time value changed by the portamento time changing means is compared with a predetermined portamento on/off threshold, and the comparison result is Therefore, key assigner selection means for selectively activating the normal key assigner means or the portamento key assigner means is provided, and when the portamento key assigner means is selected, the portamento frequency control means controls the portamento time. An electronic musical instrument characterized in that frequency control is performed according to portamento time changed by a changing means.
