摘要：An electronic musical instrument comprises a tone generator for generating aplurality of different digital waveform signals corresponding to different timbres, and adevice for setting a plurality of ranges defined by two parameters, a first one of theparameters being a pitch parameter and a second one of the parameters being a keytouch parameter. The parameters vary according to the musical performance, and arange for the pitch parameter in combination with a range for the key touch parameterrespectively designating one of the plurality of different digital waveform signals havingdifferent timbres. An input device is provided for inputting the two parameters accordingto a musical performance. A judging device judges a respective range to which each of theinputted two parameters belongs, and a selector selects one of the plurality of digitalwaveform signals from the setting device corresponding to a judged result to generateone of the plurality of different digital waveform signals from the tone generator, theplurality of different digital waveform signals thereby being selectively generated inorder to output a sound having a corresponding timbre in response to the two

parameters thus inputted.
