AJH Synth DH-ADSR Envelope Generator Eurorack Module, Silver

Main Features

• Full DH-ADSR module for EuroRack systems
• Uses the same circuitry as the Dual Contour ASD module
• Retrigger mode for automatic retriggering of the envelope
• Can be used as a complex LFO in Retrigger mode
• Delay-Hold Mode
• Slow mode for very long envelopes
• Silver fascia panel

The MiniMod DH-ADSR Envelope Generator is a compact 10hp wide Eurorack format module.

The MiniMod DH-ADSR 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: AJH 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 they have included 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.
