BS-RoFormer SW (6-stem) — mirror

Unmodified mirror of enerjazzer/BS-ROFO-SW-Fixed: the BS-RoFormer SW checkpoint, 6 stems. Kept here so Trainspotting Suite can pin a stable copy after the original author's (jarredou) Hugging Face account was deleted. The .ckpt and .yaml are byte-for-byte mirrors; the GGUF is a format conversion of that same checkpoint.

Stems

Output order, from BS-Rofo-SW-Fixed.yaml: bass, drums, other, vocals, guitar, piano. 44.1 kHz stereo. The GGUF carries num_stems = 6 but not the stem names, so callers must use this order. (The GGML/BSRoformer.cpp CLI writes them as stem_0 … stem_5.)

SHA256SUMS lists all three. The GGUF is q8_0 with norms/biases/band_split projections kept F32 (their widths aren't q8_0 block-aligned) — mixed quantization, ~175M params.

Runtime

gguf loads with BSRoformer.cpp (CPU / CUDA / Vulkan / Metal) — one artifact, no Python ML stack. Converted with its scripts/convert_to_gguf.py --arch bs --dtype q8_0. Verified on Apple Silicon: a 12 s stereo excerpt separated in 2.75 s on Metal, all six stems returned, and the stems sum back to the mix at correlation 0.9997 (residual −38.9 dB).
