DUAL VC ENV

A single module combining an ADSR and a DADSR-type, CV-controllable envelope generator.

The envelope generators operate in either GATED or TRIGGERED mode, which determines 

LEGATO or STACCATO playing behavior.

• Gated – The envelope remains active as long as the gate signal is held. In legato playing, it does not retrigger.
• Triggered – The envelope restarts with every new note, regardless of the gate signal state.

Both generators offer selectable linear or exponential curve shapes. Each envelope has separate GATE and TRIG inputs, which can be linked.

The second envelope, of the DADSR type, can be delayed between 0 and 2 seconds, and its output can be switched from 0–10 V to ±5 V. The first envelope has a default output range of 0–10 V, and both envelopes feature inverted outputs.

Attack, Decay, and Release times are adjustable between 2 ms and 10 s, while the Sustain level ranges from 0 to 10 V.

The Dual VC ENV module includes two independent, assignable CV inputs, which can be mapped to any parameter via the HIDDEN PARAMETERS menu.
