Music

submit_music returns a generation jobId; call track_progress until every result is saved in the media pool. Placement, trim, loop, fades, and ducking remain timeline operations.

Providers and modes

Provider	Modes	Reference
mureka	instrumental, song, prompt-song, soundtrack, track	references/mureka.md
minimax	t2m, cover	references/minimax.md
atlas	t2m	references/atlas.md
sonilo	v2m	references/sonilo.md

Select the named/configured vendor. Default to Mureka instrumental for ordinary BGM. Use Mureka song/prompt-song when its vocal or reference controls are wanted; use Mureka soundtrack for an image/video-driven score and track mode for generating a stem/track from a song/audio source. Use MiniMax for its text-to-music and cover models. Use Atlas Cloud for schema-backed text-to-music through its asynchronous audio API. Use Sonilo v2m when the music should be composed from the finished cut itself (a project video asset) rather than a text description.

Shared workflow

1. Confirm provider, mode, and whether multiple paid variants are wanted.
2. Read the provider reference and pass only that provider's parameters.
3. Submit once, then call track_progress({ target:"generation", action:"wait", jobIds:[jobId] }).
4. Use every returned asset when count produced multiple results; do not assume only the legacy result field exists.
5. Place/trim/duck on the timeline only after actual durations are known.

Examples

// Mureka instrumental (default count is deliberately 1)
submit_music({ provider: "mureka", mode: "instrumental", prompt: "Warm lo-fi piano bed under narration", count: 1 });

// Mureka lyrics song
submit_music({
  provider: "mureka", mode: "song", prompt: "Bright modern pop", gender: "female", count: 2,
  lyrics: "[Verse]\nCity lights open the night\n[Chorus]\nWe build the future in real time",
});

// Mureka prompt song
submit_music({ provider: "mureka", mode: "prompt-song", prompt: "A hopeful road-trip anthem", styles: ["pop", "folk"] });

// Score a project video or image
submit_music({ provider: "mureka", mode: "soundtrack", sourceAssetId: "videoAssetId", prompt: "Tense restrained documentary score" });

// Generate a stem from a Mureka song id
submit_music({ provider: "mureka", mode: "track", songId: "song-id", trackType: "Drums", prompt: "Tight punchy acoustic drums" });

// MiniMax instrumental / vocals
submit_music({ provider: "minimax", mode: "t2m", prompt: "Upbeat electronic tech intro", isInstrumental: true });
submit_music({ provider: "minimax", mode: "t2m", prompt: "Rainy night pop", lyricsOptimizer: true });

// MiniMax cover from a project audio asset
submit_music({ provider: "minimax", mode: "cover", prompt: "Warm acoustic coffee-shop cover", referenceAssetId: "audioAssetId" });

// Atlas Cloud text-to-music
submit_music({ provider: "atlas", mode: "t2m", prompt: "Cinematic ambient score with restrained piano", isInstrumental: true });

// Sonilo video-to-music from the rendered cut (prompt optional)
submit_music({ provider: "sonilo", mode: "v2m", sourceAssetId: "renderedCutAssetId" });
submit_music({ provider: "sonilo", mode: "v2m", sourceAssetId: "renderedCutAssetId", prompt: "Warm indie folk, no drums" });

Rules

• Only generate after an explicit request; count 2–3 can multiply provider charges, so never add variants silently.
• Mureka stream:true enables the provider's streaming task phase, but OpenChatCut still waits for durable final files.
• MiniMax cover requires a configured music-cover* model and exactly one of referenceAssetId or coverFeatureId; coverFeatureId also requires lyrics.
• Atlas Cloud supports t2m only and does not accept MiniMax cover/optimizer or Mureka-specific controls.
• Never mix MiniMax audio-setting fields into Mureka or Mureka IDs/modes into MiniMax.
• Generated music does not guarantee exact beat/drop timing; cut and align after generation.
