Erica Synths Black EG2 Exponential ADSR Envelope Generator Module - BEG2

The GATE LENGTH setting allows you to generate a full ADSR envelope even from very short trigger signals. This provides more control over the envelope's duration independently of the input trigger's length.

In LOOP mode, the Erica Synths Black EG2 outputs a full ADSR envelope cycle repeatedly, rather than a simpler AD (Attack-Decay) contour. This is useful for creating sustained, evolving sounds.

Yes, the GATE LENGTH feature can be manually set or controlled by an external CV (Control Voltage) source, allowing for dynamic and modulated gate durations.

While it functions as a standard envelope generator, its unique features like CV-controlled gate length and ADSR looping are best utilized by those familiar with modular synthesis concepts. Beginners might find it slightly more complex than a basic EG.

The module accepts standard trigger or gate signals from sequencers, drum machines, or other envelope generators.

It requires standard Eurorack power, typically +/-12V or +/-15V depending on the case, with the correct ribbon cable connection. Always check the module's specific power requirements.

The output is an analog control voltage (CV) signal representing the envelope's shape.

Check that the module is properly powered, and that output is patched correctly to another module. Verify that input trigger/gate signals are present and at an appropriate level.

Ensure the GATE LENGTH is set appropriately or controlled by CV. If in LOOP mode, confirm that the sustain level is set to allow the release phase to be heard.

Verify the CV source is patched correctly to the GATE LENGTH CV input and is providing a suitable voltage range. Check that the manual GATE LENGTH knob is not fully overriding the CV input if that is the intended behavior.

Confirm the power cable is correctly oriented and securely connected to both the module and the Eurorack power supply. Check the Eurorack case's power status.
