YuE2 tips: KSampler ~16x faster, CFG sweet spots, LoRAs and 900s song fix
Diligent-Rub-2113 · reddit · 2026-09-20
Tested on an RTX 5060 Ti 16GB + 64GB RAM PC, the 3B local music model YuE2 gets major free wins over ComfyUI defaults: dropping KSampler steps from 32 to 6 (8x faster) plus switching dpm2 to dpmpp2m (another 2x) yields 16x faster sampling — a 5-minute song went from 34s to 2s with no audible quality loss in blind A/B tests.
Other findings: CFG 1 is fastest and most stable (CFG >3 damages frequencies); community LoRAs improve mastering (narlorajointv9) and reduce repetitive instrumental patterns (arlorainstv3abc, strength 0.7 on CLIP slots); updated ComfyUI raises max song length from 360s to 900s and fixes covers drifting out of sync after 50s. Prompt augmentation with Gemma 4 (int8 convrot) now takes 10s for style tags and lyrics, 2x+ faster. YuE2 also accepts editable ABC notation for melody/harmony/rhythm control — the author used it for a Super Mario ska cover.
