[[File:Hordijk_de.png|thumb|right|200px]]The 2U wide '''Rob Hordijk Dual Envelope Generator''' module (DUAL ENV) is a fully voltage controlled envelope generator specifically designed to be used with sequenced music. There are two different types of envelopes available, one is a four stage (attack, decay1, break level, decay2, release) envelope and the second is a one stage envelope (decay only). Both envelope generators share the same gate input, meaning that they can not be triggered separately. Triggering treshold is at roughly 100mV above ground and also accepts e.g. triangle waves.

When the decay2 knob on the first envelope generator is fully open the decay2 acts like the sustain that you find on most of the traditional envelope generators. In this case the break control will act like the sustain level. There are CV inputs for the attack, decay1, decay2 and release rates. The CV for the attack is inversed, so increasing the CV level will shorten the attack time while increasing the decay times for the decay1, decay2 and release. This means that when e.g. the key velocity voltage is used a higher velocity will shorten the attack and increase the other decay times. Rate settings can be from really snappy to pretty slow. Care was taken that you still have good control over the rates when in the snappy range.
