Tackleberry Delay

A clean digital multi-tap delay — up to eight taps reading one shared circular buffer, with global feedback, tempo sync and stereo width — feeding Denzel’s dynamic-EQ + multiband-distortion engine on the wet, with a Post/Feedback EQ-placement toggle. Brain-free in v1.

Quick start

  1. Insert on a send/aux or an insert with Dry/Wet pulled back.
  2. Add taps with + Add Tap; set each tap’s time / level / pan in the stem editor.
  3. Turn SYNC on to lock tap times to note divisions, or off for free ms.
  4. Set Feedback and Width, then colour the wet with the dynamic EQ / drive — choose Post or Feedback placement.
01

Multi-tap delay core

Up to 8 taps read ONE shared stereo buffer at their own fractional offsets — not N separate delay lines.

Taps (1–8)

The + chip adds a tap; REMOVE takes out the selected one (the taps after it move down one). Per tap: time, level, pan, mute.

TAPS screen

A coloured stem per tap: drag its height for LEVEL, its dot on the row beneath for PAN; its TIME is written under it. Clicking a stem selects that tap.

Selected tap: Time · Level · Pan · Mute

The chosen tap’s TIME (note division on SYNC, milliseconds on FREE), LEVEL, PAN and MUTE — the first control the mute setting has had.

Clean read + crossfade

4-point Catmull-Rom cubic interpolation on every fractional read — no saturation, wow/flutter or drift in the delay path. A tap-time move crossfades (~20 ms) between old and new read positions instead of jumping.

Tempo sync

Global SYNC toggle. On: each tap picks a note division (1/1…1/32, dotted & triplet) locked to host BPM. Off: free-time ms (1 ms–4 s).

Global feedback

A single feedback gain on the summed tap output, recirculated into the buffer. It is scaled by how loud the taps are between them, so the repeats never grow: with several loud taps the top of the knob means “ring for a very long time” rather than a runaway. A soft limit on what recirculates is the safety net. Low and medium settings sound as they always did.

Width

Stereo width (mid/side) on the wet.

Dry/Wet

The final mix (last delay knob).

02

Wet processing & placement

Dynamic EQ + drive

Six bands, identical to Denzel’s engine (static + up/down dynamics) plus per-band drive shapers — on the wet only.

MAG / PHASE view

MAG is the familiar magnitude response; PHASE swaps in a −180°..+180° grid on the same log-frequency axis and draws the wet EQ’s own summed phase response, low cut included — from the exact audio coefficients, so it cannot drift from what you hear.

Sidechain (SC)

Each dynamic band can key off an external sidechain — standard use: duck the delay repeats from the dry source.

Low Cut

A high-pass on the wet signal only, 0–500 Hz (fully down = Off), in the delay strip. The setting always existed; the rack face is the first to give it a control.

EQ placement: Post / Feedback

Post (default): buffer stays clean, EQ/drive shape the summed wet after the taps — every repeat coloured identically (mirrors Wallace). Feedback: the EQ’d wet recirculates, so each repeat is progressively re-coloured (classic dub “grimy tail”), and every repeat still lands exactly on time.

Delay times, levels, pans and presets are starting points. Validation checklist from the build spec: click/zipper on time sweeps, sync accuracy under BPM change, feedback stability at max, and CPU at max taps + full feedback + sync on a small buffer.
