The Erica Synths Envelope Generator 2 is a re-triggerable, looping envelope generator with some unconventional features that are very useful for experimental setups. What sets the Black EG2 apart from other envelope generators is its optional GATE LENGTH setting, which allows for generating full ADSR envelopes even if a short trigger is used at the input. Likewise, in LOOP mode, the module outputs a full ADSR envelope instead of a classical AD envelope. The gate length is both manual and CV controlled, which allows for using this envelope generator in compact modular setups controlled by trigger sequencers only. SPECS: Gate input level 3...10V Envelope amplitude 0...10V Attack time 0...7,4" Decay time 0...19" Sustain level 0...10V Release time 0...17" Gate length 0...3,7" Panel width 8HP Module depth 25mm Power consumption 29mA@+12V, 33mA@-12V LOOP/SINGLE Select between SINGLE SHOT or LOOP modes. When the internal gate is o , the rise and fall times are set via the A and R knobs. When the internal gate is on, all knobs have an e ect on the envelope shape. The LED gives visual feedback on the envelope state. GATE ON Engage the internal gate and you have a full ADSR envelope in loop mode and with a trigger applied to the trigger input in single mode. G. LENGTH Set the internal gate length manually LENGTH CV This is the internal gate length CV input. The CV is added to the gate length potentiometer setting GATE This is the GATE input A / D / S / R These knobs adjust envelope stage times and sustain level TRIGGER This is the TRIGGER input. You can retrigger the envelope and start the attack stage again, even if the gate is still high (see Figure 1). If you wish to use the envelope generator with an internal gate, patch the incoming trigger signal here. The internal gate is linked to the trigger input, not the gate input. EG OUT This is the envelope generator output.
