Envelope Generator (ADSR) Overview
The ADSR section is a four stage envelope generator that smooths the shape of
incoming trigger or gate signals to produce more expressive control voltages. The
ADSR output can be used to control the amplitude of an oscillator, the cutoff
frequency of a filter or any other function on a module that accepts control
voltages.
The incoming gate or trigger signal passes through each of the four stages to
output an envelope. When the ADSR module receives a gate or trigger signal, the
attack determines the amount of time needed for the envelope generator to
reach the peak output voltage and move on to the decay stage. Decay sets the
amount of time needed to transition to the level set by the sustain knob. The
sustain level is maintained as long as the incoming gate remains on or high. Once
the incoming gate goes low or off, the release knob sets the time needed to
close the envelope and return the ADSR output to 0 volts.
