The EG-16 is an advanced delay, attack, hold, decay, sustain, release envelope generator with envelope curve options and CV inputs for each phase of the envelope.
The delay knob changes the delay phase time from 0 ms to 10 seconds.
The attack knob changes the attack phase time from 0 ms to 10 seconds.
The hold knob changes the hold phase time from 0 ms to 10 seconds.
The decay knob changes the decay phase time from 1 ms to 10 seconds.
The sustain knob changes the level that the envelope remains after the decay phase.
The release knob changes the release phase time from 1 ms to 10 seconds.

Logarhythmic, Linear, or Exponential
The EG-16 delay, attack, hold, decay, sustain, release envelope generator is the most versatile in the world of synthesizers. The envelope shape can be logarithmically curved for more natural movement, linear, or exponential.
When using the EG-16, wire a gate signal into the gate socket. Any signal can be a gate signal, but typically you would use the GATE outputs on the master module.
When the gate signal is above 0 volts, the envelope triggers. If the gate signal remains above 0 volts, the phases of the envelope generator will trigger in order (delay, attack, hold, decay).
The delay phase delays the attack phase. If the delay phase is long, it will sound as if the envelope is not working. The envelope is working, it just has not reached the attack phase. The delay phase can be triggered during the release phase without affecting the release curve.
The attack phase is similar to the attack phase on other envelopes.
The hold phase keeps the envelope at maximum output after the attack phase until the hold timer is finished.
The decay phase reduced the envelope output until it hits the sustain level.
Once the decay phase is complete, the envelope output level will remain at the sustain knob value.
When the gate signal is 0 volts or less, the envelope triggers the release phase. Making the gate signal 0 volts can be done by releasing the keyboard key.
The curve button will change the envelope shape from logarithmic, to linear, and to exponential. Experiment with the curve to get the desired envelope response.
IMPORTANT: The envelope curve will effect the output level of the sustain. At 50% sustain; a logarithmic curve will make the sustain lower, a linear curve will keep the sustain at 50%, and an exponential curve will make the sustain higher. The envelope output will always be within a range of 0 - 1 volts.
Each phase of the envelope can be modified by CV input such as an LFO. The CV input will change the phase values in sometime unpredictable ways.
IMPORTANT: When modifying a phase, set the knob to the center position you want the modulation to achieve. At counter clockwise values, little or no change will occur.
