SoniloMusic15 - ComfyUI Built-in Node Documentation - ComfyUI

The Sonilo Music 1.5 node generates a complete song with sung vocals from a text prompt. Describe the genre, mood, instruments and vocals, and optionally supply your own lyrics; the node sends the request to the Sonilo service and returns the finished track as audio. Use it when you need a full song rather than an instrumental clip.

Inputs

Parameter	Description	Data Type	Required	Range
`prompt`	Description of the song: genre, mood, instruments and vocals. To set the words yourself, add a `Lyrics:` block with `[Verse]` and `[Chorus]` tags; without one the model writes its own lyrics. Must be 1 to 2000 characters after trimming whitespace.	STRING	Yes	1 to 2000 characters
`duration`	`auto` fits the song length to the lyrics. `custom` uses the `seconds` value, cutting lyrics that do not fit and repeating short ones.	DYNAMIC_COMBO	Yes	`"auto"` `"custom"`
`seed`	Seed controls whether the node should re-run; results are non-deterministic regardless of seed (default: 42).	INT	Yes	0 to 18446744073709551615

Custom Duration Parameters (when `duration` is `"custom"`)

Parameter	Description	Data Type	Required	Range
`seconds`	Length of the generated song in seconds (default: 60).	INT	Yes	10 to 360

Note: The prompt input is required and must not be empty. The node validates that it contains at least 1 character after trimming whitespace and no more than 2000. Note: Usage is billed at $0.0032175 per second of the requested duration, and the price badge follows duration.seconds when custom is selected.

Outputs

Output Name	Description	Data Type
`audio`	The generated song, including vocals, as an audio file.	AUDIO
