AJH Synth MiniMod DH-ADSR Envelope - 10HP (Silver) [DEMO]

The MiniMod DH-ADSR Envelope Generator is a compact 10HP wide Eurorack format module. It has been developed to offer a full ADSR envelope for the MiniMod system and of course other Eurorack synthesisers, as an alternative to the original Model D style contour generators which do not have separate Decay and Release controls.

The DH-ADSR uses exactly the same discrete transistor circuitry as the original Model D contour generators, so it retains all of the "punchiness" of the original, along with it's unique multiple key trigger behaviour; we have simply added a Release control so that it now offers a true ADSR envelope, and the Decay and Release curves can be individually controlled.

But included are three exciting new features too:

Delay-Hold Mode which can generate very complex envelopes when mixed with another regular envelope generator output.

Retrigger mode which allows automatic re-triggering of the envelope, the Pre-Delay control sets the "hold off" time between individual retriggers, and the Hold control sets the gate length, so it can produce repeating ADSR envelopes, this has a very wide range and even be used as an LFO.

Slow mode, this switches the envelope down to 1/5th of regular speed, so slow, evolving envelopes are now possible too.

Features

• DH-ADSR Envelope
• Inspired by the Moog Model D discrete transistor circuitry
• More stages than just ADSR, includes Pre-delay, and Hold
• Positive and negative outputs
• Slow switch for increasing envelope length
• Retrigger switch to loop envelope, makes LFO
