Mureka AI Mureka V9 Generate Song (Official Edition)

This is the payoff node for the whole Mureka shelf in BizyAirPlus. Everything else in the family - the lyrics LLM, the Extend Lyrics, the BGM generator - feeds into this one: it takes real lyrics and turns them into a finished song with vocals. If you're building a music pipeline in ComfyUI, this is where it pays out.

What it is

Mureka V9's official text-to-audio full-song generator, surfaced as an "Official Edition" BizyAir node. It's the vocal version of the BGM node: lyrics in, complete sung track out, rendered in the cloud.

How it works

The lyrics input is the song's text - up to 3000 characters, and structure matters. Mureka reads your section markers ([Verse 1], [Chorus]) and sings them as written, so the quality of your lyric scaffolding is the quality of the song. n (1–3) sets how many takes to render per request. Then the fun part - the optional audio inputs that let you steer the sound instead of rolling dice:

• melody - control production with a melody reference.
• reference - control the overall music with a reference track.
• vocal - control the voice itself through a timbre reference.

Want a specific singer's vibe, a melody you hummed, or a production style? That's where you put it. prompt adds up to 1024 characters of extra direction on top.

The inputs and outputs

• lyrics - required (up to 3000 chars).
• n - required, 1–3 tracks.
• melody / reference / vocal - optional audio steering.
• prompt - optional text direction.
• outputs - audio, request_id, and urls (direct links to the rendered tracks).

api_config and skip_error are the pack standard.

Installing

ComfyUI Manager → "BizyAirPlus", or:

cd ComfyUI/custom_nodes
git clone https://github.com/siliconflow/BizyAirPlus.git
cd BizyAirPlus
python -m pip install -r requirements.txt

Restart, turn the BizyAirPlus button ON, enter your API key from bizyair.ai.

Where people get burned

The usual suspects plus one big one. URL-hosted audio references (local files won't upload themselves), and n multiplying your bill. But the big one is structure: Mureka sings your lyric file's structure, and if your lyrics are a wall of text, you get a wall of sung text. Build verse/chorus/bridge scaffolding in the cheap LLM node first. And know the platform context - Mureka's generation is watermarked and content-filtered like its peers, so this is a tool for legit production, not a loophole.
