The EG is an envelope generator that packs a wealth of functions into a compact 2HP aircraft. It has an attack and decay stage, and each stage can be set to a length of 3 milliseconds to 11 minutes. In addition, the curve characteristics can be switched between linear type (LINEAR) and exponential type (EXPO), and attack time and decay time can be controlled by CV as well as the knob.

You can also adjust the size of the output envelope with the AMP knob. The voltage at the top of the envelope is 0V on the far left and 10V on the far right.
