4.6 AMPLITUDE ENVELOPE




The amplitude section contains an ADSR envelope and a distortion module. The ADSR envelope is used to shape the note volume over time. So a sound starts at silence then fades to its maximum volume, then it decreases in volume till it reaches its sustain level and when the note is released the volume slowly fades to silence.

Distortion is an effect which boosts the sound volume and clips it at a certain level, which gives the sound an extra edge. In the extreme case, any signal will become a block shape. The distortion type selects between a loud distortion and a soft distortion. The distort knob determines the amount of distortion.
