Piano
Consider using Unwa BS-Roformer Resurrection inst a.k.a. “unwa high fullness inst" on MVSEP as preprocessor - rainboomdash
- Logic Pro (paid; May 2025 update, SDR 7.79) / BS-Roformer 6 stems / MVSEP Piano SW
(“1000 times more efficient than the Lalal.ai piano model”)
- Lalal.ai (paid; no other stem with piano stem attached)
- Demix Pro (paid; “I often combine the two” - Mixman, but it was before the 6 stems above)
- MVSep Piano Ensemble (Mel-Roformer + SCNet Large piano models; SDR 6.21)
(Mel is viperx' iirc; “a [tiny] bit more bleed during the choruses and whatnot” vs x-minus, “works well maybe 7 times out of 10”; SCNet, “has a less watery sound, but more bleed” vs Mel)
- x-minus.pro (for paid users; cheap subscription; “more consistent than MVSep piano and demucs_6s” it knows well what piano is, but it sounds the best for other stem of piano separation, but e.g. on Carpenters - Yesterday Once More “while not terrible, the dropouts, underwater 'gurgles', and general lack of piano punch/presence remains noticeable” - Chris_tang1, while MVSEP Piano Ensemble: SCNet + Mel, SDR: 6.21, was much better in that case - might vary on a song)
- Music.ai (paid)
- Dango.ai (paid)
- GSEP (formerly best, paid)
- Moises (separate models for piano and keys)
- MVSep Piano MDX23C 2024 & 2023
- htdemucs_6s (not too good)
- MVSEP Digital Piano (much better for epiano, and sometimes also for real or synthesiser when it's picked vs the SW model)
- MVSep Keys
- MVSep Harpsichord
- MVSep Celesta
- MVSep Vibraphone
- MVSep Metal Bars
- MVSep Rhodes
- MVSep Mellotron
- MVSep Clavinet
- Piano in BS-Roformer “MVSep Mega 53 Stems” model | single models (less VRAM-hungry) - 1.27GB | MVSepless HF / HF CPU / Colab (you can pick which stems you want there)
- MVSep SATB Choir (it's able to separate piano layers; consider using good instrumental model result as an input passed through e.g. BS-Roformer SW piano stem, and then SATB for fuller sound instead of using “Extract vocals option”)
