Overview

A Direct Way to Rework a Song's Instrumentation

Start with an existing track and guide a new instrumental direction from one focused brief.

Source First

Build From an Existing Song

Use your own audio or a saved AceStep track as the musical source. The editor starts from real song context instead of asking you to reconstruct the whole composition.

Arrangement Control

Describe the Backing You Want

Set the genre, instruments, groove, tempo feel, energy and production character with style tags that guide the new generation.

Song Context

Add Lyrics When They Help

Include optional lyrics and section markers when the arrangement should respond to verses, choruses or other structural cues.
