Scenario ACE-Step Music

Overview

ACE-Step 1.5, a music production family on Scenario, splits every mode into its own model: Text to Music, Cover, and Repaint each in a Turbo and a Quality lane, plus a full-quality edit trio (Add Layer, Complete Track, Stem Extract), nine members at authoring time. Discover them with search, pick the member by mode name, and treat model_schema_get as the contract.

Connection and the core loop: see the scenario skill in this repo; model-agnostic audio work: the scenario-audio skill. If a sibling skill named here is missing from your available skills, ask the user to install it (npx skills add scenario-labs/skills --skill <name>); unattended, proceed from tool schemas and flag the gap.

Quick reference

Mode Key inputs Behavior
Text to Music prompt or lyrics (either suffices) full song; duration 10 to 600 s (empty lets the model pick), bpm, keyscale
Cover srcAudio (+ referenceAudio) restyles a song; audioCoverStrength sets how much of the original survives
Repaint srcAudio + window regenerates repaintingStart to repaintingEnd in place, length preserved
Add Layer srcAudio + trackName + prompt adds one stem matched to key, tempo, and groove, optionally windowed
Complete Track srcAudio + completeTrackClasses + prompt arranges stems around a partial recording (Vocal2BGM)
Stem Extract srcAudio + trackName isolates one stem from a mix
