Not yet. StemDeck currently ships with htdemucs_6s, and there is no general model-loading interface today. This is something I’m actively exploring. MDX-Net and RoFormer are especially interesting because different models can perform better on different instruments and mixes. I agree that running the same track through multiple models and A/B comparing individual stems would be far more useful than presenting one model as universally “best.” The difficult parts are model licensing, package size, hardware requirements, and providing a consistent output format across models. I also want to avoid making every user download several gigabytes of weights they may never use. The likely approach would be optional, on-demand model downloads with cached results and a model selector. So the short answer is no today, but alternative models and proper A/B comparison are absolutely on the roadmap. Contributions and model recommendations are very welcome thoyugh :)
