Synths
- MVSep Synth (it can also pick some bass which some bass models failed to pick up)
- MVSep Organ
- BS-Roformer “MVSep Mega 53 Stems” model (has these two; smaller/muddier) | single models (less VRAM-hungry) - 1.27GB | MVSepless HF / HF CPU / Colab / newer (you can pick which stems you want there)
- Piano or guitar models might work (if the song doesn't have piano or guitar already) depends on a song
- lalal.ai (hit or miss, sometimes might not work)
- Some voc/inst models might treat synths as vocals (then you could separate them using better inst/voc model)
