DPLR Eurorack Dual/Stereo Delay Cheat Sheet

Overview

DPLR is a dual/stereo delay module with voltage control, cross-channel feedback (XTALK), and variable low-pass filtering. It offers classic, ping-pong, and experimental delay effects.

Inputs and Outputs:

Jack Function Notes/Voltage Range
IN Signal input to the delay Audio level (typical modular)
DLY CV CV input for main DELAY time (A/B) 0–5V CV
SPRD CV CV input for SPREAD (offset delay for B) 0–5V CV
RGN CV CV input for REGEN (feedback amount) 0–5V CV
OUT A Main delay output + mixed B XTALK Audio out
OUT B B delay out, affected by SPREAD/XTALK Audio out

Controls:

Control Function
D / DELAY AMOUNT Sets delay time (40ms – 700ms, manual & CV)
R / REGEN AMOUNT Adjusts feedback for repeats, manual & CV
S / AMOUNT Sets WET signal (0%–100%; 2x gain at max)
L1 / DELAY A Delay time for A output (linked to DELAY knob)
L2 / SPREAD (B) Offsets B delay from A, ping-pong/dual delays
M / MODE SELECT XTALK / FILTER Tap to cycle XTALK (cross-feedback) modes, hold for filter slope levels

Button/LED Functions:

Control Function
XTALK LEVEL LED Shows XTALK amount (RED: none, BLUE: max)
FILTER SLOPE LED Shows low pass filtering level (brighter = more filtering)
M / MODE Button Short press: XTALK mode; Hold 1s: Filter slope mode

XTALK Modes:

FILTER Modes:

Basic Use:

  1. Patch Input: Send audio to IN jack.
  2. Set Delay: Rotate D/DELAY AMOUNT knob to adjust time; patch CV for modulation.
  3. Spread for Stereo: Use L2/SPREAD knob to offset B channel; CV input for animation.
  4. Adjust Feedback: R/REGEN knob for repeats; patch CV for evolving textures.
  5. Wet/Dry Mix: S/AMOUNT knob combines dry/wet; max = all wet (x2 gain).
  6. Experiment with Modes: Tap M for XTALK; hold for filter.
  7. Output: Use OUT A and/or OUT B for mono or stereo effects.

Tip: Use XTALK and SPREAD to create dynamic ping-pong delays, stereo widening, or wild feedback networks!
