Inputs (11)
| Name | Type | Default | Description |
|---|---|---|---|
| prompt | STRING | A description of the music style, mood, genre, and scenario. 10-2000 characters. | |
| lyrics | STRING | Lyrics of the song. Use \n to separate lines. Supports structure tags: [Intro], [Verse], [Pre Chorus], [Chorus], [Post Chorus], [Hook], [Bridge], [Interlude], [Transition], [Build Up], [Break], [Inst], [Solo], [Outro]. Max 3500 characters. Required when is_instrumental is false. Empty leaves it out. | |
| lyrics_optimizer | BOOLEAN | false | When true and lyrics is empty, auto-generates lyrics from the prompt. |
| is_instrumental | BOOLEAN | false | When true, generates vocal-free instrumental music. |
| audio_setting_sample_rate | COMBO | 44100 | Sample rate of generated audio |
| audio_setting_bitrate | COMBO | 256000 | Bitrate of generated audio |
| audio_setting_format | COMBO | mp3 | Audio format |
| max_cost_usdopt | FLOAT | 20.00–100000 | Safety cap. If the estimated cost of this run is above this many US dollars the node stops BEFORE sending anything to fal. 0 = no cap. |
| reuse_identical_runopt | BOOLEAN | true | If these exact inputs (the settings AND the same pictures/clips/audio) were already paid for and the files are still in output/fal, return them instead of paying again - also after a ComfyUI restart. Turn off for a fresh take with the same settings. |
| extra_jsonopt | STRING | Advanced: a JSON object merged into the request last, for any fal field this node has no box for. Example: {"seed": 7}. Leave empty normally. | |
| max_concurrentopt | INT | 11–32 | How many paid fal calls may run at the same time in one run, across every fal node. 1 (default) = one after another. This node starts its paid part only while fewer than this many fal calls are running. Once any fal node fails, the ones still waiting are not started, so nothing more is billed. |
