Next gen stems
...in Serato.
GOOD CLEAN STEMS is a free Mac stem splitter built around current, high-performing, community-driven separation models for DJs and producers. No subscription and no paywall in front of an open sourced project packed into a GUI. Local MLX processing on Apple silicon handles high-quality vocal isolation, acapella extraction, and four-stem separation with a dedicated model for each phase. Export the stems, bring your own, or combine studio files into Serato sidecars for native playback.

FIRST PASS
Give every stem the right set of ears.
Drop in a song, choose the outputs you need, and get industry-leading vocal isolation, acapella extraction, or four-stem separation locally. In published benchmarks, Kim Vocal 2 produced a signal-to-distortion ratio about 51% higher than fine-tuned Demucs v4, while Kim FT measured 46% higher. Choose Kim FT3, FT2 Bleedless, Leap, or Leap XE for the vocal pass. Kim Inst V1E handles the instrumental pass, while BS-RoFormer-SW handles four-stem separation. On the same Apple silicon hardware, MLX ran up to 2.50x as fast as PyTorch across the tested model families.
