v3.0 — CORE/DATA split, confidence marking, five platforms

A complete rewrite. Twelve files, 415 KB, replacing the ten-file v1.1 layout.

Try it without installing anything — a ready-made Gem with everything loaded: SunoForge v3.0

Works at both ends

Know nothing about music? Write what you want the way you would say it to a friend — "something sad but not depressing, with a piano, for the end of a video". You get finished prompts, ready to paste. No terminology, no menu numbers, nothing to configure first.

Know exactly what you want? The same system goes down to tempo and key, spectral brightness of a timbre, where the groove sits against the beat, stereo depth and reverb decay, slider values per genre, section-by-section performance notation, chord progressions inline, mastering thresholds and ratios. The vocabulary file alone is 42 KB of descriptors; the recipe library carries 45 presets with BPM, key and sliders already dialled in.

Neither audience has to grow into the other.

Why this version exists

Three independent fact-checking passes in July 2026 found that both previous editions were presenting community folklore in the voice of documentation. Four load-bearing "mechanics" did not survive:

Taught as fact	What checking found
MAX MODE — a hidden quality mode	No such mode. Controlled comparison found no difference beyond ordinary variance
Two-Minute Drift — tracks degrade after ~2 min	Anecdotes only. No systematic testing, no vendor acknowledgment
[Reverb: 30%], [BPM: 120] and similar	Never parsed by any covered platform
A ~200 character Style limit	Wrong — it made users cut prompts to a fifth of the working range

Nothing was deleted quietly. DATA_SUNO §13 keeps every myth alongside what checking actually showed, so the system can recognise and repair them when they arrive from older guides.

What is new

Confidence marking. Every claim about platform behaviour carries [OFFICIAL], [COMMUNITY] or [UNVERIFIED]. An unmarked claim is a defect. This field has very few primary sources, and most circulating advice is one person's experience retold as fact — now the reader can tell which is which.

A CORE / DATA split. Between March and July 2026 every platform fact broke at least once: the default model version, Lyria's track length, the name of Flow Music, the Studio version, stem mechanics, the lyrics editor — and two products shut down entirely. Not one prompting rule broke. So they no longer share a file. DATA_* files carry a date in the name and an expiry notice; updating for a new quarter means replacing them and leaving CORE_* alone.

Five platforms. Suno v5.5 (Duration Slider, the Exclude Styles field, Voices, Custom Models, Studio 1.2, three stem modes), Google Lyria 3 Pro / Clip / RealTime with the official [MM:SS] timestamp format, Google Flow Music, ElevenMusic, Stable Audio 3.0.

Udio is no longer a target — downloads were disabled after the UMG settlement. It stays in the legal file as a cautionary case.

A repair engine. Menu entry [12] diagnoses an existing prompt against 14 checks and repairs dead constructs: parametric tags, MAX MODE remnants, the wrong Lyria timestamp syntax, negatives that backfire, references to retired platforms.

An explanation layer. /why <topic> returns the reasoning behind a rule — what it is, why it works, what breaks if you ignore it, and why the myth spread. Loaded on demand, so it costs nothing until asked for.

Compatibility

Menu numbers [1]–[12] are frozen as a public interface; new entries go at the tail only. Old prompts keep working — run them through [12] to see what no longer does.

Verification

Seven build invariants checked mechanically rather than by inspection: single source for version data, menu number consistency across files, no parametric constructions outside the myths sections, no cross-file duplication, confidence tag coverage, expiry headers on dated files.

Two live runs before release produced eight further fixes, including one from a first-hand measurement: 7 minutes 59 seconds on the free v4.5-all tier in a single generation — which contradicts the widely repeated claim that the free tier caps out around two minutes.

Downloads

SunoForge_v3.0_en.zip and _ru.zip hold the same twelve files and differ by one line — the language of explanations. Prompts themselves are always English, because the platforms handle it best. Switch any time with /set lang en or /set lang ru.

DATA_bundle_for_Gemini.zip is a convenience: Gemini Gems cap attachments at 10 files, so the five CORE_* files plus this one archive fit where twelve separate files do not. See docs/GEMINI.md.

Earlier versions

v1.1 (March 2026) is tagged retroactively. v2.0 was never released here — it was Russian-only and shipped on the 4PDA forum.
