ENVELOPE GENERATORS (EGS)
The EGs produce a control voltage that varies over time. Typical used to shape the volume of a sound
when controlling the VCA, or the tone, when controlling filter cut-off.
But can also be used to modulate, say, the pitch, for drum effects, or, pulse width, for brassy sounds.
There are two EGs and they are identical to each other.
A control
Attack: This controls how low the EG takes to reach maximum level once triggered.
D control
Decay: After reaching maximum level following the Attach stage, Decay sets the time taken to
reach the level set by Sustain.
S control
Sustain: Once the Attack and Decay stages have passed, Sustain sets the level that the EG will
hold its output at for as long as a key is held down.
R control
Release: Once the key is released, this sets the time take for the signal to fade to zero.
