Manual

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)

Added with the + Add Tap tile, removed with each column’s red minus. Per tap: time, level, pan (mute retained in state).

Tap editor

A colour-coded vertical stem per tap: TIME dropdown (note division on SYNC, ms slider off), LEVEL / PAN drag handles.

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. Kept < 1 with a soft write clamp so it can’t run away.

Width

Stereo width (mid/side) on the wet.

Dry/Wet

The final mix (last delay knob).

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.

Phase (all-pass) + MAG/PHASE

The wet EQ includes 2nd-order all-pass Phase bands — unity magnitude, rotating phase up to 360° around freq without changing tone or level — plus the MAG / PHASE curve toggle (the phase view draws the summed phase response from the exact audio coefficients). Useful for nudging the repeats’ phase against the dry so a stacked wet/dry doesn’t comb.

Sidechain (SC)

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

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”).

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.
