Get unstuck

On a machine without a usable NVIDIA GPU, separation runs on the CPU, which is much slower. Each track only needs separating once — the result is cached and reused. The quick approximate stems are available immediately while the neural ones compute.

Until the neural stems finish (the header shows neural stems (100%)), you are working with fast approximate stems that leak between parts. Wait for the refined stems, then try again. Heavily layered passages may still leave some of a part behind.

Open the boundary and use the entry nudge (−10 / −1 / +1 / +10 ms) to line B's kick up with A's. If the whole track's grid is slightly out, use the beat grid slip in the bottom pane. Blends that start in a section with no steady kick are aligned on the grid instead.

Use the bar line arrows (◂ ▸) in the track pane to move the bar line by a beat so phrases line up.

Mixdis assumes each track holds a steady tempo through a blend. Tracks that change tempo mid-song have a low-confidence grid and are better mixed using their steadier sections. If the same tracks drift in your DJ software too, BeatDis writes drift-following beatgrids into Serato and Rekordbox.

Drift lets each track play at its own tempo and ramps smoothly between them across each blend. Locked holds the whole set at the first track's tempo, time-stretching every other track. Pitch is preserved in both.

Ctrl Z (or ⌘ Z on a Mac) undoes edits, marker moves and fades; the arrows in the toolbar do the same.

Export renders through the same engine as playback. Make sure analysis has finished refining stems before exporting, and check the output format and bit depth in the export menu.

Check the region is on the track you're listening to and that it covers the part you're playing. A Build starts at nothing and a Release ends at nothing, so set the shape to Hold to hear it at full depth. On a filter, From and To both sitting at “open” is no filter at all.

Reverse plays a pre-rendered copy of its region. That render happens in the background, so it passes through until it's ready — a second or two for a long region. Exporting waits for it.

Their length is the effect: use the Speed slider (fast is short, slow is long) or drag the region's edge. With Snap on, an edge snaps to whole bars, so hold Alt while dragging for a short one.

Yes. Every effect has a target menu next to its kind: whole track, drums, bass, melody or vocals. With the DSP fallback stems (before the neural ones finish) the stem split is approximate.

Not at present — macOS builds target Apple silicon.
