D-ENV QUICKSTART GUIDE

CONTROLS

VintageSynthLab.com

DELAY

Sets the amount of delay time (from 12
ms to 1050 ms) between an incoming
gate or trigger received at the D-G IN
jack and it’s final destination(s).

HOLD

Sets the amount of hold time (from 12 ms
to 1050 ms) for the delayed gate (only). This
affects the D-G OUT jack and the delayed
gate routing via the D-G switch. The HOLD
time is also indicated by the yellow LED
toward the top-center of the module.

ATTA CK

Sets the attack timing of the EG. This range of
timing depends on the envelope timing mode
(see also S/L control and rear jumper settings).

DECAY

Sets the decay timing of the EG.
This range of timing depends on the
envelope timing mode (see also S/L
control and rear jumper settings).

SUSTAIN

Sets the sustain level of the EG.

JACKS

RELEASE

Sets the release timing of the EG.
This range of timing depends on the
envelope timing mode (see also S/L
control and rear jumper settings).

D-T

Routes the Delayed Trigger to the EG.
This mode will also be indicated as active
while the above red LED is illuminated.

D-G

Routes the Delayed Gate to the EG. This
will also be indicated as active while
the above yellow LED is illuminated.

S/L

Sets the EG timing mode. “S” = shorter env
timing, “L” = longer env timing (including
jumper option to extend “L” mode. See
also REAR JUMPER SETTING OPTIONS).

MAN

Manual Gate triggering.

REAR JUMPER OPTIONS

GATE IN

Gate input (0 to 10V). Activates the
EG mode as: Attack > Decay >
Sustain > Release (ADSR).

TRIG IN

Trigger input (0 to 10V). Activates the
EG mode as: Attack > Release (AR).

D-G IN

Gate or Trigger input for initiating
simultaneous Delayed Gate and Delayed
Trigger function. The Delayed Gate
and Delayed Trigger will always both
be available at the D-G OUT and D-T
OUT jacks respectively, regardless
of optional routing to the EG.

D-TIME

CV (input) to Delay Time. Note that the
DELAY (time) control will determine the
maximum amount of available delay,
hence it will “scale” the available delay
range, regardless of CV input voltage.

ENV OUT

AR/ADSR Envelope output (0 to 10V).

INV OUT

Inverse of AR/ADSR Envelope output (10V
nominal, 0V at peak of envelope waveform).

D-G OUT

Delayed Gate output. A delayed gate
signal will be available here when a gate
or trigger is present at the D-G IN jack.

D-T OUT

Delayed Trigger output. A delayed trigger
signal will be available here when a gate or
trigger is present at the D-G IN jack. The
Delayed Trigger will produce a fixed pulse­width signal of about 525 µs (or 0.525 ms).

P2 HEADER

The P2 header allows for extension of the
“L” (long) envelope timing by a factor of
three (x 3). The two positions available
are: “Long:10x” and “Long:30x). The
Long:30x mode is *approximately 3 times
longer than the standard Long:10x mode
(*see specifications for actual timing).

P3/P4 HEADER

The P3 and P4 headers allows for Unipolar
or Bipolar CV optimization for the D-TIME
CV input jack. Set both jumpers to the same
setting, either “U” for Unipolar (0 to +5V)
or “B” for Bipolar (-5V to +5V). Note that
the relationship between a linear CV and
the resultant DELAY time is exponential.
