Chained separation order
With single stem models below, feel free to experiment with different orders of sequential stem separation to enhance separation results:
#1
1) Well sounding result from instrumental model/s first 2) drums or bass 3) piano or guitar 4) strings or horns
Note: If your song has “weird percussion that don't get picked up by drum models and if it's piano-heavy, I would go for piano first, but it sometimes leaves piano behind” - Isling
#1b
1) Instrumental separation 2) drums 3) (other of drums to) bass 4) (other of bass to) 5) guitar/piano/other instrument
“If it's a rap song (...) I have seen better result separating it this way, than using either the other of the bass or the other of the drums to get the melody” - Infisreal
So basically, on an already well sounding instrumental you should start with "separating the drums, using the other from the drums for the bass, and the other of the bass for the melody, whether it's piano, guitar, synths etc.”
#2
1) Instrumental model first 2) drums 3) piano 4) strings or horns 5) bass 6) guitars
This way once someone “ended up with a decent 5th-stage “other” stem that seemed to contain some unknown synth sounds + possible orchestra hits” vs when bass was after drums when “gave me a messy “other” with stray piano & strings content” - SilSinn9821
#3
“After each [removal], you also remove some useful parts for [the] next instruments. So I'd propose to first use the models with the best quality. Anyway, in the end others can be very muddy” - ZFTurbo
#4
1) Bass Ensemble (SCNet XL + BS Roformer + HTDemucs4) 2) Drums MVSep SCNet XL 3) Piano MVSep SCNet Large 4) Organ MelRoformer 5) Saxophone MelRoformer 6) MVSep Wind Ensemble (SCNet + Mel) 7) MVSep Guitar Ensemble (BSRoformer+ MelRoformer) 8) MVSep Strings” - dynamic64
“I think this is my new default [order]”
Example: “Personally, I like putting the instrumental through MVSep bass model (above), then putting the other stem through MVSep drums (specifically SCNet XL), then putting the other stem of that through the 6 stem model [a.k.a. SW]
The 6 stem model is best for piano and guitar, and separating out the drums and bass beforehand helps that model not have to work as hard.
And it also allows you to manually add anything that the first 2 models missed, because its a 6 stem model, and re-separates any missed drum and bass.
Creates close to studio results. As close to studio as I've ever heard”
#5
In case of ensembling various models of the same stem, if the top model in terms of SDR doesn’t have significantly lower metric, sometimes it’s better to use it instead of ensemble [esp. if it doesn’t have any crossbleeding] - dynamic64.
Just be aware that it might vary from song to song
#Tip
“Drums model often bleeds the bass and 808s into the drum track, [using bass model] prevents this issue from happening”
