Stem Separation splits an audio clip into individual stems — vocals, drums, bass, and instruments — using AI models that run locally on your Mac.
Gridshift integrates third-party AI models for source separation. The specific algorithms may change over time as better models become available.
Models
Models are downloaded on first use. All processing runs locally — no audio is uploaded.
Separate a clip into stems
Open the Command Palette and search
Open the Command Palette (⌘K) and search for “Separate” or “Split Clip into Stems”.
Choose Song Stems or Drum Elements
Choose Song Stems or Drum Elements.
Stem separation only works on audio clips. If a MIDI clip is selected, the Command Palette will show a hint to select an audio clip instead.
Output
Gridshift creates a group track with one child track per stem, time-aligned with the original clip. The original clip remains unchanged.
Each stem track is a regular sample track — you can apply effects, time-stretch, edit in Focus Mode, or use as a sidechain source like any other track.
In-place stems in the Sample Editor
If you want to mix the stems as a single instrument rather than arrange them independently, generate them inside the Sample Editor instead. The Sample Editor’s Stems mode bakes the same models against the current sample and exposes per-stem volume, mute, and solo controls on a stack of lanes — all on the original track.
