YuE2GenerateABC - ComfyUI Built-in Node Documentation - ComfyUI

This node generates ABC notation for a song based on a style description and lyrics, using a YuE2 text-and-lyrics model. The resulting abc output can be connected to the YuE2 Generate Music node to produce audio.

Inputs

Parameter	Description	Data Type	Required	Range
`clip`	The YuE2 model used to tokenize the style and lyrics and generate the ABC notation.	CLIP	Yes	-
`style`	Text describing the musical style of the song. Supports multiline input and dynamic prompts.	STRING	Yes	-
`lyrics`	Text containing the lyrics of the song. Supports multiline input and dynamic prompts.	STRING	Yes	-
`seed`	Random seed used for generation. Changing it produces different results. Default: 0.	INT	Yes	0 to 18446744073709551615
`mode`	full: generates melody and chords; melody: generates melody only, recommended for covers.	COMBO	Yes	”full" "melody”
`max_abc_tokens`	Maximum number of tokens generated for the ABC notation. Default: 8192. Advanced setting.	INT	Yes	1 to 20000
`temperature`	Controls the randomness of the generated tokens. Higher values produce more varied output. Default: 0.7. Advanced setting.	FLOAT	Yes	0.0 to 5.0
`top_p`	Nucleus sampling threshold; only tokens within this cumulative probability are considered. Default: 0.9. Advanced setting.	FLOAT	Yes	0.01 to 1.0
`top_k`	Limits token selection to the K most likely tokens. Default: 30. Advanced setting.	INT	Yes	1 to 32768
`repetition_penalty`	Penalty applied to repeated tokens during generation. Default: 1.005. Advanced setting.	FLOAT	Yes	0.01 to 10.0
`penalty_window`	Number of recent ABC tokens used to penalize repetition. Default: 100. Advanced setting.	INT	Yes	1 to 20000

Outputs

Output Name	Description	Data Type
`abc`	The generated ABC notation of the song, which can be connected to the YuE2 Generate Music node.	STRING
