。[Scope of Claim for Utility Model Registration] An envelope generator that generates an envelope waveform for controlling the characteristics of a musical tone, comprising upper and lower limit value setting means for setting at least one of an upper limit value or a lower limit value of the envelope waveform, and a predetermined envelope waveform. Generating an envelope waveform to be applied to a musical tone based on the information, and when the waveform value of the waveform exceeds the upper limit value set by the upper and lower limit value setting means, the upper limit value is lowered below the lower limit value. An envelope generation device comprising: envelope waveform generation means that sometimes outputs the lower limit value as a waveform value of the envelope waveform.
