Patent ID: 7732701

Claim:
An electronic musical instrument, comprising: a keyboard that has a plurality of keys that designate a pitch; key operation detection means for detecting the operating state of the keyboard; a set operator that switches to a parameter setting state; parameter value input means for inputting the parameter values; pressed key count detection means for detecting the number of keys pressed; parameter setting means for setting the parameter values according to the pressed keys as detected by the key operation detection means; and a parameter output means for outputting the parameter values that were set by the parameter setting means; wherein, in the parameter setting state, the number of keys pressed is detected by the pressed key count detection means; wherein when the pressed key count is one, the parameter values are set based on the parameter values that have been input by the parameter value input means for the pressed key as detected by the key operation detection means; and wherein when the pressed key count that has been detected by the pressed key count detection means is greater than one, the parameter values are set based on the parameter values that were input by the parameter value input means according to the keys that have been pressed as detected by the key operation detection means.
