AJH Synth stayed close to the original when designing the envelopes, even the internal operational voltages have been taken into consideration. The retrigger behaviour of the transistor based envelopes is special, because when re-triggering the envelope, it did't restart at 0V but at the momentary voltage. At longer decay settings the envelope got louser and louder, up to 10.5V.
The Minimoog envelopes had three parameters only: attack, decay and sustain. The release was switchable and it's length was determined by the decay parameter. You could use them either as attack-decay envelopes or attack-decay-sustain-decay. In the Dual Countour module this is selectable per envelope.
The envelopes can be fired manually with buttons.
AJH Synth bring the earliest Minimoog Mk1 into Eurorack, carefully cloning the internal discrete transistor-based circuitry, using operating and CV voltages and even modifications were included.
Same sweet sound but without the disadvantages of the original like rarity, high price, S-Trig and unstable VCOs.
