The brain

The brain is our own program, under the GNU GPL version 3, with its source published at github.com/stonecorestudio/zammoth-brain. It is built with Python and about sixty open-source packages - among them Pedalboard (GPLv3), NumPy, SciPy, ONNX Runtime and Anthropic's Python SDK - under MIT, BSD, Apache 2.0, MPL 2.0, PSF and LGPL licences. Each is listed with its version and licence text inside the app, at Contents/Resources/mixagent_daw_brain/_internal/THIRD_PARTY_PYTHON.txt. The Python runtime brings OpenSSL (Apache 2.0) and Zstandard (BSD) with it; both texts are in the same file.

Stem separation

Splitting a track into stems uses demucs-onnx (MIT) running Meta's Hybrid Transformer Demucs model (MIT). The model is not part of the app: it is downloaded from Hugging Face the first time you split a track.
