Matched-budget Hybrid Demucs

We train Hybrid Demucs on bass, drums, guitar, and piano packs under a matched step budget for Slakh, SPDMX (BDGP), and Slakh ∪ SPDMX. In-domain SI-SDR is strong for each solo arm; cross-domain transfer is weak, consistent with prior synth–synth mismatch findings. Full numbers are in the ICASSP draft Table 2.
