It’s a method utilizing old models, and e.g. Kim Vocals 2 can be potentially replaced by unwa’s BS/Mel-Roformer models in beta UVR (or other good method for vocals) or ensembles mentioned in this document. Check the best current methods for vocals in one stem to find what works the best for your song to get all vocals before splitting to other stems using this diagram.

htdemucs v4 above can be replaced by htdemucs_ft, as it's the fine-tuned version of the model (or MDX23 Colab). Even better, you can use some of the methods for 4 stems in this GDoc (like drums on x-minus).

De-echo and reverb models can be potentially replaced by some better paid plugins like:

DeVerberate by Acon Digital, Accentize DeRoom Pro (more in the de-reverb section).

UVR Denoise can be potentially replaced by less aggressive Aufr33 model on x-minus.pro (used when aggressiveness is set to minimum), and there’s also newer Mel-Roformer (read de-reverb section).

As for Karaoke models, there's e.g. a Mel-Roformer model on x-minus.pro for premium users or MVSEP/jarredeou inference Colab.

"If the vocals don't contain harmonies, this model (Mel) is better. In other cases, it is better to use the MDX+UVR Chain ensemble for now.". It is possible to recreate to some extent this approach while not using BVE v2 models, by processing the output of main vocal model by one of Karaoke/BVE models in UVR (possibly VR model as the latter) using Settings>Additional Settings>Vocal Splitter Options, so it separates using one model, then it uses the result as input for the next model (see the Karaoke section).

MedleyVox (not available in UVR) will be useful in the end in cases when everything else fails after you obtain all vocals in one stem, as it's very narrowband. But you can use AudioSR on it afterwards.
