SA3 Drone Bender — bending direction vectors
Contrastive bending direction vectors for the SA3 Drone Bender JUCE plugin: a real-time contrastive-DiT-bending + drift/feedback-loop instrument built on a C++/MLX port of Stable Audio 3.
Files
| File | Size | Description |
|---|---|---|
bending_directions_medium.safetensors |
244K | 5 contrastive bending direction vectors (layers 4-11 of the medium DiT) |
5 semantic direction vectors (Harmonic Brightness, Melodic Activity, Textural Density, Rhythmic Intensity, Register) extracted via contrastive analysis of the medium DiT's internal activations (layers 4-11), used to steer generation in the Drone Bender's "Bend" XY pad.
Base model weights
This repo does not host the base Stable Audio 3 weights. Get those from
maxgraf/sa3-variations-models
— an MLX/safetensors port of Stability AI's stabilityai/stable-audio-3-optimized
medium bundle: dit_medium_f16.safetensors, same_l_encoder_f32.safetensors,
same_l_decoder_f32.safetensors, t5gemma_f16.safetensors.
bending_directions_medium.safetensors must sit alongside
dit_medium_f16.safetensors in the same models directory — the orchestrator
loads it as a sibling file.
Usage
The setup.sh
script in the plugin repo downloads all five required files (four from
maxgraf/sa3-variations-models, this one from here) and builds the plugin in
one step. To fetch just this file manually:
hf download Danhearn/sa3-drone-bender bending_directions_medium.safetensors \
--local-dir /path/to/models
License
bending_directions_medium.safetensors is original work derived from Stable
Audio 3's medium DiT internal activations, released under the
Stability AI Community License for
consistency with the base model weights.
