Open-source ComfyUI node turns instrumental tracks into sung songs with your lyrics
White_Dragon_0 · reddit · 2026-11-03
The author released YuE2 Auto Vocal PRO v2, a ComfyUI custom node solving a key YuE2 limitation: SheetSage2-extracted ABC notation usually routes melody to the instrumental track, leaving the vocal track empty so YuE2 has no melody to sing. The node automatically transfers the instrumental melody into the vocal track, letting YuE2 sing your custom lyrics over an instrumental.
Key features:
- Section awareness (verse/chorus/intro/solo/outro) to avoid vocals on instrumental passages
- Preserves the original melody without rewriting notes
- Three lyrics alignment modes: matchsections, reportonly, repeatexisting (never invents words)
- Built-in lyrics-melody diagnostics (bars per line, syllable estimates, notes-per-syllable ratio) to debug "la la la" non-lexical outputs
- Complete example workflow included, open-sourced on GitHub
