System Documentation

What problem does it solve?

This Skill helps you create and edit music without manual production work by generating audio from text tags and by repairing or extending existing tracks.

Core Features & Use Cases

  • Tag-driven music generation: produce stereo audio using the StepFun-AI ACE Step open-weights model via the runcomfy CLI.
  • Multilingual vocal and structured lyrics: use ACE Step 1.5 for 50+ languages and section markers like [Verse], [Chorus], [Bridge], [Outro].
  • Audio inpainting and outpainting: regenerate a specific time range (inpaint) or extend a track before/after (outpaint) while keeping style consistent through tags.

Quick Start

Ask your agent to generate a short instrumental track by tags using the ace-step text-to-audio endpoint.
