The D-ENV is a 10hp Eurorack format Envelope Generator with the addition of Delay and Hold functions for gates / trigger. Delayed gates and triggers can be taken directly from dedicated output jacks, in addition to routing to the ADSR function. Exponential envelope generator (ADSR / AR) with independent delayed gate / trigger processing (up to 1 second), and delay-hold (up to 1 second).
 
3 Env timing ranges (Short timing fixed range. Long timing can be extended for Extended-Long timing.)
Dedicated input for CV to Delay time
Dedicated outputs for Delay signal + Hold signal for Gate/Trigger Delayed outputs
Dedicated Inverted ADSR output
Dedicated, separate Trigger and Gate inputs

Delayed Gate/Trigger can be routed internally at the push of a switch, and when active, are logically "OR'd" with any income gates or triggers entering the envelope generator's gate and trigger input jacks.

Delayed gates only accept new gate signals once the entire Delay and Hold cycles are complete. Delay cycle starts once a signal at the D-G IN jack is received (rising edge -or- positive-going). Both the Delay and Hold cycles are minimum 12 ms, and maximum 1050 ms, each, and are sequenced from Delay to Hold.

DELAY Timing (for both Gate & Trigger)
Min Delay Time = 12 ms
Max Delay Time = 1050 ms
Delayed Gate Width (HOLD) Timing
Min Delayed Gate width = 12 ms
Max Delayed Gate width = 1050 ms
Delayed Trigger Width Timing

CV to Delay (via D-TIME input jack)

Exponential response to linear CV in either “U” (+ Unipolar), or “B” (Bipolar) mode

Unipolar mode: 0v to +5V (jumper option selected on rear of PCB as header “P3 & P4”)
Bipolar mode: -5v to +5V (jumper option selected on rear of PCB as header “P3 & P4”)
Positive going CV increases delay-time
