Lyrics Room — Suno Director v4 (Q8_0 GGUF)

The Suno Director v4 turns a sung lyric draft into a Suno v5.5 performance score. Fine-tuned from unsloth/gemma-4-12b-it.

• Quantization: Q8_0 (lyrics-room-suno-director-v4.Q8_0.gguf, ~12.67 GB)
• Serving: LM Studio / llama.cpp / Ollama as lyrics-room-suno-director-v4

It adds cue-before-line vocal notes, free-form bracketed arrangement cues, and intro/outro floods. It must not change a sung word. If a draw rewrites lyrics, discard it and retry at temperature 0.2.

The official critic/judge prompt pack lives on the Structured Panel card.

How it works

Suno reads the lyric sheet top to bottom. A cue placed after the line it describes is usually ignored or sung. This model:

1. Puts (Vocal: ...) / (Production: ...) notes above the line they affect
2. Inserts free-form [a low kick enters] cues as their own lines
3. Floods intros, breakdowns, and outros so Suno does not hum
4. Copies every sung lyric line verbatim

It can write lyrics if you feed it an empty draft, because it was trained on Topline Writer sheets. That is not the intended seat. Write with Topline Writer v9, then annotate here.

Isolation example

[Mood: late-night analog]
[Energy: Medium]
[Instrument: clean electric, analog kick]

[Intro]
[solitary clean electric guitar weaves minor melody over amp hum]
[sub-bass enters on beat four]

[Verse 1: intimate baritone, close room]
(Vocal: dry intimate baritone, close-mic)
Two amps turned to gold across the festival rail
(Vocal: rasp on edge, slight delay tail)
Dust on the fader, quiet on the gale

Where it sits

graph TD
    A[Creative Director] --> B[Topline Writer v9]
    B -->|sung draft| C[Suno Director v4]
    C -->|performance score| D[Critic Panel + Producer Judge]
    D -->|repair then re-enrich| C

Run this model before the first critic pass so the panel scores the arrangement sheet. After a Topline repair, run it again.

Sampling: temperature 0.2, max_tokens 1024, JSON { "lyrics" }. One hardened retry if the preservation check fails (sung-word count or sung lines changed).

Official prompts

System

You are the Suno Director enriching lyrics into a studio-grade Suno performance score. Return ONLY lyrics in JSON format.

User

Enrich this Suno lyric draft into a studio-grade Suno performance score.

Length budget: target {min}-{max} sung words, firm minimum {softMin} sung words even for sparse styles, never exceed {hardMax} sung words or 5000 characters. Resolved genre: {genre} from {source}.

V1 SUNO SONG CONTRACT:
- Output only the song lyrics. No commentary.
- Start with [Mood: ...], [Energy: Low|Medium|High|Very High], [Instrument: ...].
- Use bracketed section headers. Never use parenthetical (Verse)/(Chorus) labels.
- Treat the supplied title as locked.

SUNO SCORE CONTRACT:
- PRIMARY VEHICLE: free-form bracketed cues on their own line, placed immediately BEFORE the moment they shape.
- INTRO FLOOD (REQUIRED): open with an [Intro] of three to six distinct free-form cues. If the draft opens cold on a sung section, add this intro above it.
- Flood intros, breakdowns, drops, and outros. Lead most sung sections with one arrangement-change cue.
- Keep section headers short (two to five words of vocal/energy stance). Put instruments/FX in cues, not in the header.
- SECONDARY VEHICLE: typed parentheticals right before the line they shape:
  (Vocal: ...) (Production: ...) (Arrangement: ...) (FX: ...) (Dynamics: ...)
  (Rhythm: ...) (Mix: ...) (Performance: ...) (Transition: ...) (Instrumental: ...)
- Do NOT wrap typed labels in brackets. [Vocal: ...] is wrong; (Vocal: ...) is right.
- Do not rewrite, shorten, add, or remove sung lyric lines.

SUNO DIRECTOR PRESERVATION CONTRACT:
- Include every original sung lyric line exactly once, in the original order.
- Preserve every original vocal section.
- Header label text is not sung content; you may rewrite [Verse 1] into [Verse 1: intimate baritone, close room].
- Adding a flooded [Intro] of non-sung cues does not violate preservation.

STYLE:
{style}

TITLE:
{title or (untitled)}

CREATIVE BRIEF:
{brief JSON}

CURRENT SUNG WORD COUNT: {n}

CURRENT LYRICS:

{topline draft}

Instructions:
1. Must preserve sung words, title anchor, section order, story continuity, and word count.
2. Include every original sung lyric line exactly once. Do not rewrite sung lyric lines, shorten the lyric, add sung lines, or remove sung lines.
3. Preserve every original vocal section.
4. You may add or improve top tags, enriched section headers, typed production notes, local [Energy: ...] tags, and genre-aware Suno control language.
5. Upgrade generic cues into specific studio direction tied to the style and creative brief.
6. Return only the full enriched lyrics in JSON "lyrics".

Hardened retry (only if the first draw changed sung content): prepend this block to the same user prompt:

RETRY — PRESERVATION FAILURE:
Your previous enrichment was REJECTED because it changed the sung lyric. This is your final attempt.
- Copy every sung lyric line VERBATIM, character for character, in the exact same order. Do not reword, merge, split, reorder, add, or delete any sung line.
- Keep the exact same number of sung words ({n}).
- You may ONLY insert new bracketed tags, timeline cues, enriched section headers, and parenthetical typed notes BETWEEN the untouched sung lines.
- If an edit might change a sung line, do not make it.
