Abstract
Abstract An electronic musical instrument, which is configured to simulate one or more instruments, provides a sound source, a display unit and a control portion. Herein, under control of the control portion, the display unit displays the predetermined graphic pattern corresponding to the tone-generation mechanism, i.e., tone-generation algorithm of an instrument to be simulated. The sound source contains a drive portion, a tone-generation portion and a resonance-radiation portion, each of which further contains a digital signal processor (DSP). All of these portions function to create a digitized musical tone signal corresponding to a simulated sound of the instrument by combining operation data outputted from the DSPs. By controlling the display unit, it is possible to arbitrarily vary the contents of the displayed tone-generation algorithm, so that the performer can easily and freely perform a music on this electronic musical instrument.

Claim 2
Dependent Claim
103 words
An electronic musical instrument comprising a drive means for generating an excitation signal corresponding to tone-generation energy; a tone-generation means for resonating said excitation signal to thereby output a resonated signal; a plurality of drive algorithms and a plurality of tone generation algorithms representing different operation manners of the drive means and tone-generation means, respectively; display means for displaying a graphic pattern representative of a selected drive algorithm and a selected tone-generation algorithm; and algorithm control means for varying the operation manners of said drive means and said tone-generation means to operate in accordance with the displayed pattern as selected by a performer.
Claim 3
Dependent Claim
105 words
An electronic musical instrument for simulating plural instruments comprising: sound source means for outputting a musical tone signal in accordance with a tone-generation algorithm which is pre-defined for each of instruments to be simulated; display means for displaying a representation of said tone generation algorithm in form of a predetermined graphic pattern comprised of plural portions of musical instruments which may be selected by a performer; and algorithm control means for controlling said display means in accordance with an operation made by a performer to display selected portions of musical instruments and for varying the contents of the tone-generation algorithm to correspond to the display.
Claim 4
Dependent Claim
105 words
An electronic musical instrument for simulating plural instruments comprising: sound source means for outputting a musical tone signal in accordance with a tone-generation algorithm which is pre-defined for each of instruments to be simulated; display means for displaying a representation of said tone generation algorithm in form of a predetermined graphic pattern comprised of plural portions of musical instruments which may be selected by a performer; and algorithm control means for controlling said display means in accordance with an operation made by a performer to display selected portions of musical instruments and for varying the contents of the tone-generation algorithm to correspond to the display.
