Inputs (10)
| Name | Type | Default | Description |
|---|---|---|---|
| prompt | STRING | The text prompt describing the music to generate Empty leaves it out. | |
| composition_plan | STRING | The chunk-based composition plan for the music JSON. Empty leaves it out. | |
| music_length_ms | INT | -1-1–600000 | The length of the song to generate in milliseconds. Used only in conjunction with prompt. Must be between 3000ms and 600000ms. Optional - if not provided, the model will choose a length based on the prompt. -1 leaves it to the model. |
| force_instrumental | BOOLEAN | false | If true, guarantees that the generated song will be instrumental. If false, the song may or may not be instrumental depending on the prompt. Can only be used with prompt. |
| seed | INT | -1-1–2147483647 | Random seed to initialize the music generation process. Can only be used with composition_plan. The same seed with the same parameters gives more consistent results, but exact reproducibility is not guaranteed. -1 leaves it to the model. |
| output_format | COMBO | mp3_48000_192 | Output format of the generated audio. Formatted as codec_sample_rate_bitrate. So an mp3 with 22.05kHz sample rate at 32kbs is represented as mp3_22050_32. Note that the μ-law format (sometimes written mu-law, often approximated as u-law) is commonly used for Twilio audio inputs. |
| 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. |
