Abstract
Abstract An electronic musical instrument for causing a tone generator to generate a musical tone corresponding to a musical performance while controlling an envelope by operation of a pedal. An operated-amount signal generator is provided for detecting an operated amount of the pedal and for generating an operated-amount signal, and an effect adding unit is provided for controlling parameters for effect addition so as to add an effect to a musical tone generated from the musical tone generator in accordance with the operated-amount signal from the operated-amount signal generator. The operated-amount signal from the operated-amount signal generator is changed by the operation of the pedal, and an effect-adding parameter in the effect adding unit is changed accordingly, to thereby add an effect to the generated musical tone.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
205 words
A musical tone control system for controlling a musical tone generated from a tone generator means, comprising: a pedal means which is operable for designating addition of an envelope and an effect to said musical tone; operated-amount signal generator means, coupled to said pedal means, for detecting an operated amount of said pedal means and for generating an operated-amount signal; system control means, coupled to said operated-amount signal generator means, for outputting an envelope-control signal and for also outputting an effect control signal for changing a parameter in accordance with said operated-amount signal; envelope control means, coupled to said tone generator means and to said system control means, for controlling an envelope of said musical tone which is generated from said tone generator means, in accordance with said envelope-control signal output from said system control means; and effect adding means, coupled to said tone generator means and to said system control means, for adding said effect to said musical tone in accordance with said parameter which is changed by said effect control signal which is output from said system control means, said parameter thereby controlling the addition of said effect to said musical tone as a function of the operated amount of said pedal means.
Claim 2
Dependent Claim
205 words
A musical tone control system for controlling a musical tone generated from a tone generator means, comprising: a pedal means which is operable for designating addition of an envelope and an effect to said musical tone; operated-amount signal generator means, coupled to said pedal means, for detecting an operated amount of said pedal means and for generating an operated-amount signal; system control means, coupled to said operated-amount signal generator means, for outputting an envelope-control signal and for also outputting an effect control signal for changing a parameter in accordance with said operated-amount signal; envelope control means, coupled to said tone generator means and to said system control means, for controlling an envelope of said musical tone which is generated from said tone generator means, in accordance with said envelope-control signal output from said system control means; and effect adding means, coupled to said tone generator means and to said system control means, for adding said effect to said musical tone in accordance with said parameter which is changed by said effect control signal which is output from said system control means, said parameter thereby controlling the addition of said effect to said musical tone as a function of the operated amount of said pedal means.
