17 - Default Send Rack

Purpose

This page defines a small set of named, standing send returns that every recipe can point at instead of re-specifying reverb, delay, width, and dirt from scratch each session.

The problem this solves: most recipes currently describe the same shared spaces in their own words ("filtered dark delay," "shared plate," "lush cinematic verb," "subtle width"). That means you rebuild the same returns every time and re-litigate decisions that should already be settled. Define them once, here. Then a recipe line becomes → S3 Dub Delay 15% instead of three sentences about which delay and how to filter it.

For where these spaces fight each other in the spectrum, see 18 - Frequency and Depth Map. For when to stop adjusting them, see 05 - Locked vs Taste Commit Gate. For tool-vs-tool choices behind each slot, see 16 - Overlap and Redundancy Map.

Main Rule

Build the rack once per session from a template, then reference the sends by name. Do not re-EQ or re-pick the returns mid-song.

On any standing send, the only taste knobs are:

  • Send amount (how much of a part goes to the return)
  • Feedback / decay (only on S2 and S3, only as an automated moment)

Everything else on a return — the plugin choice, the return EQ, the predelay — is locked. If you find yourself reaching for the return's plugin GUI, stop: the fix is almost always the send amount or the source, not the space.

The Rack

Five returns cover the whole guide. S5 is optional. Numbers are starting send amounts for a lead-ish element; quieter/background parts use less.

ID Name Plugin (locked) Character Default use Taste knob
S1 Dark Plate UAD EMT 140 / Lexicon PCM Plate Short–medium plate, return HPF ~200 Hz / LPF ~8 kHz Shared body for vocal, snare, synths — the "everything lives here" room Send amount (8–18%)
S2 Cinematic Lexicon PCM Hall / UAD 480L / Eventide Blackhole Long, predelay 30–80 ms, return HPF ~250 Hz Blooms and moments only — chorus lift, last-word throw, transitions Send amount + decay (automated)
S3 Dub Delay iZotope Cascadia / UAD tape echo Dotted-1/8 + 1/4, filtered dark (HPF ~200 / LPF ~3–6 kHz), low feedback Phrase answers, dub throws, motion Send amount + feedback (automated)
S4 Width UAD Dimension D / Studio D Chorus / Eventide TriceraChorus / MicroPitch Subtle stereo widen/detune, mono-safe Synth and guitar width without doubling Send amount (keep mono-compatible)
S5 Dirt (optional) iZotope Trash / Plasma (parallel) Filtered parallel distortion, HPF ~150 Hz Parallel grit blended under drums, bass-upper, or a clean synth Send amount (blend low)

Naming convention in recipes: S1 Dark Plate 12%, S2 Cinematic (throw), S3 Dub Delay 15% fb→auto. The percentage and any "(throw/auto)" tag are the taste part; the name is the contract.

Why These Five

  • S1 Dark Plate is the cohesion engine — one shared plate is most of why a mix "sounds like one record" (see 04 - Make It Sound Expensive). Filtered dark so it adds body, not fog.
  • S2 Cinematic is deliberately not an everyday space. It is loud, long, and beautiful — so it only earns its keep on moments. Keeping it off by default is what protects depth.
  • S3 Dub Delay is the movement tool the whole "effect-as-arrangement" approach leans on — throws answer phrases instead of filling gaps.
  • S4 Width keeps stereo image intentional and shared, so you stop putting a different chorus on every synth.
  • S5 Dirt exists so "make it less polite" is a send, not a per-track decision you keep re-making.

This is intentionally a closed set. A sixth standing send is almost always a moment that belongs on S2 or S3 with automation. Adding more returns re-creates the decision fatigue the rack exists to kill.

Locked Return Settings (build once)

Dial these when you make the template, then never reopen them per song:

  • S1 Dark Plate: decay ~1.2–1.8 s, predelay 10–20 ms, return Pro-Q HPF ~200 Hz + LPF ~8 kHz.
  • S2 Cinematic: decay 2.5–6 s, predelay 30–80 ms (keeps sources clear), return HPF ~250 Hz, LPF ~9 kHz if glossy.
  • S3 Dub Delay: dotted-1/8 and 1/4 tap, feedback low (automate up for special throws), return HPF ~200 Hz / LPF ~3–6 kHz.
  • S4 Width: subtle — check mono collapse; nothing should disappear or pump.
  • S5 Dirt: Trash/Plasma into Pro-Q HPF ~150 Hz so distortion never muddies the sub.

All returns are sends, ducked under the dry source — never inserts. Sub-heavy bass and the lead vocal stay mostly dry and central; let support parts and moments use the rack.

How Recipes Use It

Recipes name a send + amount instead of re-describing the space. Examples already wired in:

When a recipe genuinely needs a one-off space (a specific shimmer, a reverse bloom), that is a moment — build it as a printed/automated effect, not a new standing return. See 11 - Creative Effects and Transitions.
