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 |
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.
Shared workflow
- Confirm provider, mode, and whether multiple paid variants are wanted.
- Read the provider reference and pass only that provider's parameters.
- Submit once, then call
track_progress({ target:"generation", action:"wait", jobIds:[jobId] }). - Use every returned asset when
countproduced multiple results; do not assume only the legacyresultfield exists. - 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" });
Rules
- Only generate after an explicit request;
count2–3 can multiply provider charges, so never add variants silently. - Mureka
stream:trueenables 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 ofreferenceAssetIdorcoverFeatureId;coverFeatureIdalso requires lyrics. - 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.
