>/ ACENTAUR
TRANSPARENCY
Open foundation. Original instrument.
ACENTAUR is built on openly released music-generation technology from the ACE-Step project. ACE-Step provides the model architecture, official model weights and the underlying generation capabilities. Apple’s MLX framework provides a foundation optimized for Apple silicon.
EINAUX turns those components into a musician-facing product: a native Audio Unit with functions not present in the official ACE-Step Gradio installation like in-session capture and playback, Drag and Drop into the Arrangement Window and the TAX™ Tag-Matrix. ACENTAUR keeps a global history of all captures and generations with unique session and instance IDs, a guided setup, mlx-model packaging, revision control, validation, updates and support.
ACENTAUR is proprietary EINAUX software built with open components. Every component keeps its original authorship, license and credit.
>/ UNDER THE HOOD
From repository to instrument.
ACE-Step can be installed directly from GitHub. That is a powerful route for developers and experimenters. ACENTAUR is the productized route for musicians working in Logic Pro.
| GitHub installation | ACENTAUR |
| Clone a source repository | Install a native macOS package |
| Install Python and uv | Guided first-run setup |
| Resolve and maintain dependencies | Managed, revision-pinned runtime |
| Start a Gradio UI or API server | Open the Audio Unit in Logic |
| Select backends and model configuration | Choose a musician-facing quality profile |
| Manage model downloads manually | Persistent model packages in a chosen location |
| Work outside the DAW | Capture, audition and exchange audio in the session |
| Track files and prompts yourself | Global History |
| Update at your own risk | Tested source and model revisions |
ACENTAUR is not a GitHub interface hidden inside a plug-in. It is a managed musical instrument built around a tested local runtime.

MLX, made persistent.
ACE-Step now includes upstream MLX support for macOS. ACENTAUR builds a complete product lifecycle around it: exact source and model revisions, persistent MLX packages, validated model profiles, managed storage, reproducible updates and integration with the Audio Unit.
On Apple silicon, ACENTAUR routes the complete neural generation path through MLX — including language planning, conditioning, audio encoding, diffusion and decoding. Converted packages carry their source revision and validation metadata, so the runtime does not depend on an arbitrary collection of files left behind by a development checkout.
The difference is not simply whether MLX is switched on. The difference is whether the entire path from model download to musical session behaves like a product.
