2ENV is a dual attack - decay envelope. It can be switched between full sustain (the output remains at full level as long as the GATE input is on) and zero sustain (for percussive envelopes). Another switch (SLOW/FAST) allows selecting the time range. For manual triggering there is a button for each envelope. CV control: Both attack and decay time can be CV controlled; the CV "multiplies" the time by 1...approx. 8 times.
Module power consumption: 8 mA
The controls are grouped into 2 identical groups marked with the number 1 and 2 for each of the individual envelopes. We only describe the controls for one group as they work exactly the same for the other group.
Envelopes are one of the basic modulation sources in subtractive synthesis. They are usually used to modulate amplitude, pitch or a filter. Often you would trigger the envelope from the BUS GATE which means that if a key is pressed on a MIDI keyboard the envelope would activate and open a VCA for instance and then slowly (or fast) close it once the key is released. The envelope can also be triggered from an LFO or TRIQ164 for rhythmic or percussive uses.
The 2ENV can also trigger itself when the output ENDx is patched into the GTx. This can make an envelope into a slow moving LFO (low frequency oscillator), or oscillator in audio range, with varied waveforms depending on the attack/decay settings.
