MRG 3310 ADSR

AS3310-based ADSR

This is a classic envelope generator, based on AS3310, a clone of the CEM3310. Features a separate trigger input, normal and inverse envelope output, high quality components and careful engineering.

When the TRIGGER input is unconnected, rising and falling edges of the GATE input will trigger a classic ADSR envelope.

If the TRIGGER input is connected, a high GATE level will bring the output to SUSTAIN level, and the GATE falling edge will start the release phase. A TRIGGER input when GATE is high will start an attack/decay cycle. Attack, Decay and Release times vary exponentially with the control knob. For each of these parameters, the ratio between the longest possible time and the shortest is slightly more than 3000:1.
