ENVELOPE GENERATOR O4A

The Envelope Generator 04a is the most comprehensive contour generator that we offer.
Voltage control of envelope stages and a unique GATE HOLD function combine to make a very flexible module.

With the aid of electronic switching, the GATE HOLD function is activated by the DLY/HOLD pull-switch pot on the front panel. The HOLD feature controls the incoming Gate signal and over-rides the length of the Gate. Short gates can be increased and long gates can be reduced to blips.
The GATE HOLD provides an added dimension for controlling the envelopes response to an incoming pulse train from sequencer or keyboard.
The duration of the HOLD is also Voltage controllable. The DELAY CV input jack is electronically switched between DELAY CV or HOLD CV input to match the state of the DLY/HOLD
panel control.
