Singularity Studio Suite v3.0 — Official User Manual & Suggested Studio Workflows Playbook.

Quick-Start, Logic Pro Setup & The 5–10s Smart Learning Lock ([RECALC])

Welcome to the Singularity Audio Labs Studio Suite v3.0. Unlike open-loop “smart” plugins that only measure incoming audio once and apply a blind static preset—or un-gated dynamic processors that continuously pump, drift, and wreck mix balances during quiet song breakdowns—every Singularity processor is built around a Closed-Loop Input ↔ Output Servo governed by a deterministic Listen → Negotiate → Hard-Lock State Machine.

1.1 macOS Installation & Logic Pro Audio Units Setup

1. Standard macOS Package Install: Once our signed and notarized release installer is published (Downloads Coming Soon), run Singularity-Audio-Labs-Studio-Suite-v3.0.pkg. All 7 Audio Unit v2 (.component) bundles are installed into /Library/Audio/Plug-Ins/Components/ (or ~/Library/Audio/Plug-Ins/Components/ for user-level installs) alongside the standalone macOS applications.
2. Loading in Apple Logic Pro: Open any Audio, Software Instrument, Aux/Bus, or Stereo Out channel strip in Logic Pro (`10.7+` or `11.x` on Apple Silicon `arm64` or Intel). Click an Audio FX insert slot and navigate to:

   Audio Units → Singularity Audio Labs → [Select Processor]

3. Forcing an Audio Unit Cache Rescan (If Logic Pro Was Open During Install): Run the following command in macOS Terminal, or open Logic Pro → Settings → Plug-In Manager and click Reset & Rescan Selection:

1.2 How the 3-Stage Closed-Loop Learning State Machine Works

When you insert any Singularity processor (or a linked chain of processors) and press Play in Logic Pro on an active musical phrase, the processor advances through three deterministic states:

1.3 The ITU-R BS.1770-4 Relative Song-Break Freeze Gate

A notorious failure mode of conventional adaptive plugins occurs during a quiet vocal intro, bridge breakdown, or reverb tail (`-35 dBFS`): the adaptive detector mistakes the quiet passage for a weak signal and cranks gain or drops thresholds by `10–15 dB`. When the chorus slams back in, the track ducks violently for `1.5 seconds`.

Every Singularity Audio Labs processor incorporates an ITU-R BS.1770-4 Relative Song-Break Freeze Gate:

• Absolute Silence Floor (`< -30.0 LUFS` / `-52 dBFS` RMS): Learning timers and servo integrators pause immediately when transport stops or a track rests.
• Relative Breakdown Gate (`inLufs < programPeakInLufs - 10.0 dB`): If the current phrase drops more than `10.0 dB` below the track’s established peak program loudness, all integrators freeze in place until the main performance returns.

Control-by-Control Hardware Reference (All 7 Flagship Processors)

Every processor in the Singularity Studio Suite v3.0 pairs physical circuit modeling (`64-Bit ADAA2`, `2x/4x` polyphase oversampling, Newton-Raphson zero-delay feedback solvers, and Jiles-Atherton magnetic hysteresis) with motorized console controls. Below is the complete parameter-by-parameter reference for all 7 plugins.

Rev D/E “Blackface” FET Livery Low-Noise Articulation + Locked Static DSP

Control / Parameter	Range & Units	Hardware Physics & Studio Function
Instrument & Style Profile	38 Studio Profiles (7 Families)	Selects the universal perceptual target vector ($\Delta\text{CF}^*$, attack preservation $\rho_{\text{atk}}^*$, groove recovery $\rho_{\text{rec}}^*$, target GR, and sidechain HPF).
Circuit Topology Selector	Rev A FET, Rev D/E FET, T4B Opto, VCA Bus	Hot-swaps the underlying physical circuit solver (`2N5457` JFET conductance with continuous pinch-off, dual-slope CdS optical memory cell, or feed-forward/feedback VCA).
Input / Drive (Motorized)	-24.0 dB to +24.0 dB	Drives signal into the fixed-threshold FET/Opto stage or shifts VCA threshold while modeling `+24 dBu` input transformer saturation.
Attack (Motorized)	20 µs to 800 µs (FET) / 30 ms (VCA)	Controls onset transient capture. Clockwise is faster in classic 1176 FET modes; automatically relaxed by the closed-loop servo if pick/stick snap drops below target $\rho_{\text{atk}}^*$.
Release (Motorized)	50 ms to 1100 ms	Dual program-dependent RC discharge network ($R_{\text{rel}}, C_1, C_2$). Props up low-frequency bass periods ($f_0 < 95\text{ Hz}$) to eliminate intermodulation ripple distortion.
Ratio & All-Buttons (“British”)	4:1, 8:1, 12:1, 20:1, ALL (British)	Sets compression slope. Engaging ALL activates authentic 4-button bias contention (`~12:1` to `20:1` with S-curve plateau lag for explosive drum rooms and aggressive vocals).
Sidechain Thrust HPF	20 Hz to 250 Hz	High-pass / pink-noise tilt filter in the detector path so heavy kick or low-E palm mutes never hijack broadband gain reduction.
Output Makeup & Parallel Mix	-18 dB to +18 dB · 0–100%	Class-A/AB output transformer makeup gain (auto-matched to unity loudness) plus phase-coherent internal wet/dry parallel NY compression blend.
⚡ TEAM LINK / 🥁 DRUM LINK	Toggle + Role Selector	Joins the `< 40 ns` POSIX shared-memory bus for 5-step Duo, 9-step Trio, or 15-role Drum Kit negotiation.

Pultec Coupled Low Trick	0.0 dB to +10.0 dB (`30/60/100 Hz`)	Models the passive RC dipole interaction of simultaneous Pultec `Low Boost` and `Low Atten`—lifting sub weight while scooping `165–280 Hz` mud in one phase-coherent gesture.
Spectral De-Muffle Servo	Auto / 0–100%	Detects dull or over-damped recordings and restores `2.5–12 kHz` articulation without triggering sibilance or amp fizz.
Percussive Transient Shield	12 ms Hold Gate	Clamps dynamic notch attenuation during the first `12 ms` of drum and plucked-string attacks so snare crack and acoustic pick snap are never hollowed out.
Auto-Gain Unity Trim	±12.0 dB (Closed-Loop)	Continuously matches post-EQ loudness to pre-EQ loudness within `±0.1 dB` so EQ moves are judged purely on tone, never volume bias.

2.3 Singularity ContourBand — 4-Band Equal-Loudness Note & Register Leveler

Studio Role: Solves one of the most frustrating problems in mixing: a bass guitar, lead vocal, guitar solo, or piano part where low-register notes boom out of the speakers while high-register notes up the neck sound thin and vanish. Singularity ContourBand splits the signal across a phase-coherent 4-Band Linkwitz-Riley (`LR4`, `24 dB/oct`, `< 0.01 dB` flat reconstruction) crossover and levels every note to an ISO 226:2023 Equal-Loudness Phon Contour.

Upward Register Lift Ceiling	0.0 dB to +8.0 dB	Noise-gated upward leveling that brings thin high-register bass notes (`140–400 Hz`), quiet vocal chest syllables, or upper-fret guitar notes up to equal perceived loudness.
Downward Boom Clamp Floor	0.0 dB to -12.0 dB	Clamps resonant low fundamentals (e.g., `41–75 Hz` open E/A bass strings or `180–300 Hz` vocal proximity) without dulling upper-band attack harmonics.
ISO 226 Target Phon Curve	65 Phon to 85 Phon (`Default: 78 Phon`)	Weights inter-band energy using the international ISO 226:2023 equal-loudness contours so every note across a 3-octave run hits the human ear with identical perceived weight (reducing register spread from `12.74 dB` down to `2.85 dB`).

Suggested Track & Channel-Strip Workflows (⚡ TEAM LINK Duo & Trio Recipes)

When you stack an EQ, a note leveler, and one or two compressors on the same Logic Pro channel strip, standard plugins operate blind to one another: resonant spikes bias broadband EQ moves, and heavy compression brings up `300 Hz` mud or `3.5 kHz` glare that nobody cleans up downstream. Engaging ⚡ TEAM LINK links all Singularity plugins on that channel via `< 40 ns` POSIX shared memory (`/tmp/singularity_team_link_bus_v3.shm`) using **48 isolated IPC slots** (`38` automatic per-profile slots + `8` explicit user bus overrides) so tracks never collide.

3.1 How the 5-Step Duo (`2.25s`) & 9-Step Trio (`2.70s`) Protocols Work

When you add a third Singularity processor on the same channel—either stacking ContourBand → HorizonEQ → GravityComp or running the classic serial vocal/guitar chain HorizonEQ → GravityComp (Fast FET) → GravityComp (Slow T4B Opto) / IronBus (Vari-Mu)—⚡ TEAM LINK automatically upgrades to the 9-Step, 3-Pass Trio Protocol (`2.70s`):

• Pass 1 (Steps 1–4 · Foundation): Step 1 EQ Problem Sweep → Step 2 EQ Initial Voicing → Step 3 Comp A / ContourBand (`55%` fast peak & register leveling) → Step 4 Comp B (`45%` slow optical/tube phrase cushion).
• Pass 2 (Steps 5–7 · Cross-Stage Counter-Trim): Step 5 EQ Combined Harmonic Counter-Trim → Step 6 Comp A Handover Trim (prevents over-triggering Comp B) → Step 7 Comp B Recovery Re-Center.
• Pass 3 (Steps 8–9 · Final Verification & Hard Lock): Step 8 EQ Final Spectral Check → Step 9 Comp A + Comp B Final Output Polish (`±0.05 dB`) & Static Lock.

3.2 Copy-Pasteable Logic Pro Track & Bus Insert Chain Recipes

Complete Multi-Mic Drum Kit & Bass Bus Workflow (🥁 DRUM LINK v3.0 3-Tier Playbook)

Mixing a multi-mic drum kit alongside a bass bus is the ultimate multi-track challenge: `Kick In` and `Kick Out` comb-filter each other due to time-of-flight delay (`~1.35 ms`), `Snare Bottom` buzzes sympathetically on every kick hit, hi-hat bleed gets sucked up by snare/tom compressors, and kick and bass fight for `50–100 Hz`.

🥁 DRUM LINK v3.0 solves the entire kit and bass section simultaneously across a 3-Tier, 15-Role Hierarchical Network over `< 40 ns` POSIX shared memory—requiring zero DAW sidechain routing.

Stem Space & Reverb Matching Workflow (Singularity PrismVerb)

Singularity PrismVerb (`SGCV`) replaces static convolution impulses with a closed-loop physical acoustic model of 6 legendary recording studio chambers and plates, plus an onboard Blind Dereverberation Stem Space Learner that extracts the exact acoustic DNA from any finished record.

5.1 The 6 Modeled Famous Studio Spaces & When to Use Each

5.2 Step-by-Step: Matching a Reference Track’s Reverb with LEARN STEM

1. Insert Singularity PrismVerb (`SGCV`): Place `PrismVerb` either directly on your Vocal/Drum track (using the internal Wet/Dry servo) or on an Aux Send bus in Logic Pro.
2. Drop in Any Commercial Reference Track: Click LEARN STEM in the top header bar and drag-and-drop any finished `.wav`, `.aiff`, `.flac`, `.mp3`, or `.m4a` song file (or stream via sidechain).
3. Automatic Stem Separation & Blind Dereverberation: `PrismVerb` isolates the target stem (`Vocal` or `Drums`) and analyzes note-release decay tails to extract the reference’s exact:
   • Haas Pre-Delay (`ms`) between dry transient onset and early reflection cluster.
   • 3-Band Decay Contour $RT_{60}(f)$ across Low (`250 Hz`), Mid (`1 kHz`), and High (`4 kHz`).
   • Chamber EQ Roll-Offs (`HPF` & `LPF`) and Direct-to-Reverberant Clarity Ratio ($C_{80}$ dB).
4. Closed-Loop Lock to Your Performance: Press Play on your Logic Pro session. `PrismVerb` selects the closest physical studio chamber model, glides its motorized knobs to match the extracted reference space, and carves your dry vocal/snare fundamental ($f_0$) out of the reverb tail so your track stays `100%` upfront.

Mix-Bus Compression (Singularity IronBus) vs. Complete 5-Module Mastering (Singularity MasterDesk)

One of the most important architectural distinctions in the Singularity Studio Suite v3.0 is understanding when to insert Singularity IronBus (`SGIM`) versus when to insert Singularity MasterDesk (`SGMD`):

6.1 How the 15-Turn (3-Pass) Omniscient Mastering Negotiation Works

In a traditional mastering chain, the final brickwall limiter sits at the end of the chain forced to crush `4–6 dB` of transient life because it cannot tell the upstream EQ that an inaudible `30 Hz` rumble is eating `1.8 dB` of headroom, or ask the upstream Vari-Mu compressor and `1/2-inch` tape machine to share the density load. Inside Singularity MasterDesk, all 5 modules share a 10-Tap Shared-Memory Matrix (`Taps 0–9`) and execute 15 coordinated turns across 3 passes:

• Pass 1 (Turns 1–6 · Forward Foundation):
  • Turn 1 (`M1 PearlMasterEQ` Sweep): Sub-rumble filter (`20–35 Hz`) + dynamic solo/guitar fizz tamer (`3.2–9.5 kHz`).
  • Turn 2 (`M1 PearlMasterEQ` Voicing): Coupled Pultec LC tank (`58 Hz` boost + `168 Hz` mud dip) and Mid/Side air shelf.
  • Turn 3 (`M2 IronBus` Compression): Sets `Vari-Mu / VCA / Opto` compression (`58%` of harmonic density target) and `Ni/Fe/St` core flux.
  • Turn 4 (`M3 HorizonMS` Stereo Field): Sets `LR4` + All-Pass Bass Mono-Maker (`85–125 Hz`) and ERB Vocal Unmasking pocket.
  • Turn 5 (`M4 VelvetTape` 1/2" Deck): Sets `15/30 IPS` `NAB/CCIR` tape saturation (`42%` of harmonic density) and `1.5 ms` Velocity Bus transient rounding.
  • Turn 6 (`M5 CrownLimiter` Headroom Audit): Measures True-Peak ceiling and LUFS error at `Tap 8/9` and computes upstream headroom delegation directives.
• Pass 2 (Turns 7–11 · Upstream Headroom Delegation & Stem Relief): `CrownLimiter` delegates excess peak reduction upstream—asking `PearlMasterEQ` (Turn 7) to shave `0.6 dB` of sub-boom and align `35–110 Hz` Bessel wavefront phase, `IronBus` (Turn 8) and `VelvetTape` (Turn 10) to absorb fast snare micro-peaks, and broadcasting Mix-to-Master Stem Relief Directives to any active `HorizonEQ` / `GravityComp` instances on Kick/Bass tracks!
• Pass 3 (Turns 12–15 · Spectral Shield, Polish & Lock): Engages the 3-band `Tap 7 vs. Tap 9` Spectral Preservation Shield so limiting never alters tonal balance, locks all 5 modules (`0.000000` drift), and enables 1-Click `FINALIZE`.

6.2 Reference Track Learning (`LEARN REF`) with Bayesian Limiter De-Biasing

Conventional reference-matching plugins blindly copy a commercial track’s brickwall clipping—destroying your mix’s punch. When you load a reference track into Singularity MasterDesk (`LEARN REF`):

1. Multi-Dimensional M/S & Crest Extraction: Measures the reference’s Mid Sub (`20–90 Hz`), Mid Tilt, Side Air (`10–20 kHz`), Stereo Width $W$, raw integrated LUFS, and raw Crest Factor.
2. Bayesian Master-Limiter De-Biasing: If the reference track was hyper-clipped (`rawCrestDb < 6.5 dB` or `rawLufs > -8.0 LUFS`), our Bayesian de-biaser strips away the brickwall distortion and enforces `targetCrestDb >= 6.5 dB` so your master achieves the reference’s authority while preserving `>= 95.9%` transient snap survival.
3. 5-Module DNA Decomposition: Splits the reference’s harmonic weight `58%` into `M2: IronBus` and `42%` into `M4: VelvetTape`, matches M/S tone within `<= 0.18 dB`, and matches stereo width within `<= 1.5%`.

6.3 Commercial Delivery Targets & 1-Click FINALIZE

Genre Preset Matrix (All 38 Studio Profiles Across 7 Instrument Families)

In the Singularity Studio Suite v3.0, selecting one of the 38 Studio Profiles never loads a dumb static knob preset. Instead, it loads a Universal Psychoacoustic Target Vector ($\Delta\text{CF}^*$, attack preservation $\rho_{\text{atk}}^*$, groove recovery $\rho_{\text{rec}}^*$, target GR $G_{\text{peak}}^*$, sidechain HPF $f_{\text{sc}}^*$, global spectral tilt $\tau^*$, and 6-band target contour $[T_1 \dots T_6]$) that drives the closed-loop servos via each circuit’s sensitivity Jacobian $\mathbf{J}_{\text{circuit}}$.
