We did update for our bass models. Previously best SDR for bass was for single model HTDemucs4 FT ~12.05 and in ensemble it was 12.59. We added new model with name "MVSep Bass (bass, other)" - it's ensemble of 2 models finetuned HTDemucs4 and trained from scratch BS Roformer. This model has 2 options - you can extract bass directly from mixture or first extract vocals and after extract bass only from instrumental part.

- SDR for extracting from mixture: 13.25
- SDR for extracting from instrumental: 13.42

We also updated our "Ensemble (vocals, instrum, bass, drums, other)" and "Ensemble All In". Their SDR for bass also increased from 12.59 to 13.44.
