Erica Synths Black Stereo Delay – Cheat Sheet
A high-performance stereo delay module with tape, digital, and ping-pong modes; hold/overdub features; wide range of CV control; and dedicated trigger, reverse, and stereo spread options.

Voltage Range |
| IN L |

Controls: Knobs, Buttons, and Switches
| Control |
Function |
| TIME (large knob) |
Sets delay time: 3ms – 3s (manual); disables sync when moved; also sets stereo spread (hold ADD, twist) |
| IN LVL |
Adjusts input gain (prevent clipping; layer volume in hold/ADD mode) |
| FEEDBACK |
Sets amount of delayed signal feedback (full CW = self-oscillation) |
| DRY/WET |
Sets blend between dry & delayed (wet) signal (analog circuit; CV controllable) |
Buttons
| Button |
Function |
| TAP |
Tap-tempo syncs delay time to BPM; exit sync by turning TIME |
| HOLD |
Captures/loops up to 20s of audio; press again to exit looping; LED lit when active |
| ADD |
Overdub into hold buffer; hold ADD & turn TIME to set stereo spread; double-click or full CCW TIME to zero spread |
| REVERSE |
Reverses currently delayed signal (not hold buffer) |
Toggles/Switches
| Switch |
Function |
| PING PONG |
Toggle stereo (off) or ping-pong (on) delayed signal; in HOLD, disables spread |
| MODE |
TAPE: Tape emulation (with pitch); DIGITAL: Clean/digital (no pitch shift) |
Special Features & Tips
- CV Inputs: All CVs expect −5V to +5V for full parameter range.
- Feedback Compression: Soft-limiting prevents runaway feedback.
- Hold/Overdub: HOLD records up to 20", ADD overdubs more layers.
- Stereo Spread: In normal playback, set by holding ADD + turning TIME.
- Sync/Tempo: TAP sets delay time; turning TIME disables sync.
- Trigger Inputs: Any function button can be triggered externally by patching to its respective input (sequencer, LFO, etc).
- Reverse: Affects delayed (live) signal only; not held buffer.
Quick Reference: Typical Patch Examples
- Mono input, stereo delay: Patch to IN L only; OUT L/R gives stereo image.
- Stereo input: Patch to both IN L and IN R.
- Dual mono delay: Two unrelated signals to IN L and IN R (PING PONG off).
- Clock-synced delays: Patch clock or sequencer to TAP.
- Creative overdub: Use HOLD for live loops, ADD for layering, tweak IN LVL and feedback for evolving textures.
- CV delay time sweeps: Modulate TIME CV for flanging/chorusing.
- External triggers: Patch gates to HOLD, ADD, REVERSE for rhythmic manipulation.
