Claims

[Claims for Utility Model Registration] Sound source means for generating musical tones, operating means for outputting information that changes the characteristics of the musical sounds generated by the sound source means through external operation, and detecting the amount of operation of the operating means. and a step determining means for determining to which step a detected value detected by the manipulated variable detecting means belongs among a plurality of steps divided by a plurality of step boundary values having different values. and musical tone control data transmitting means for transmitting musical tone control data corresponding to the step value associated with the step determined by the step determining means to the sound source means to control the characteristics of the musical tone. The musical instrument includes: previous step value storage means for storing the previous step value related to the step to which the detected value last detected by the operation amount detection means; and a predetermined width provided for each step boundary value. dead band discriminating means for determining whether or not the detected value currently detected by the manipulated variable detecting means belongs to a dead band having As long as it is determined that the new step value belongs, the musical tone control data corresponding to the new step value is prohibited from being sent from the musical tone control data sending means to the sound source means, and the musical tone control data corresponding to the new step value is prohibited from being sent to the sound source means. An electronic musical instrument, comprising: control means for controlling the musical tone control data sending means so as to maintain the musical tone control data corresponding to the previous step value as is.
