Everything a blend needs
Stems, tempo, clashes, fades, effects and mashups — planned for you, editable by you.
Four-stem separation
Every track is split into drums, bass, melody and vocals by a neural separator running locally. A fast approximate split is available straight away; the neural stems replace it in the background.
GPU accelerated
On an NVIDIA GPU, separation runs on the card (TensorRT) and falls back to the CPU automatically if the GPU isn't available. Each track is only separated once; results are cached.
Key-safe tempo matching
Each track plays at its own tempo and the tempo ramps smoothly across a blend. Pitch is preserved with time-stretch, so tracks keep their own key. A Locked mode holds the whole set at one tempo instead.
Beats land on the kick
Each blend is aligned on where the kicks actually start, not just on a grid, and falls back to the grid where there is no steady kick. Fine slip and bar-line controls cover the rest.
Automatic clash resolution
Mixdis predicts vocal, melody, bass and key clashes across a blend and ducks only the stems that clash. Auto-plan picks the mix-out and mix-in points and the style for every boundary.
Fades you can see and edit
The fades chosen for a transition are drawn per stem on the timeline. Drag the start and end handles, add markers with a right-click, or ride a stem's volume across a whole track.
Bass EQ lane
Draw dB markers on the bass of either side of a boundary — smooth moves or hard steps — to make room for the incoming kick and sub.
Editable tempo ramps
The tempo change is decoupled from the gain blend: set where the BPM starts and ends moving, independently of the fades.
Non-destructive edits
Delete or repeat a section, snapped to bars, without touching the file. Song structure (intro, build, drop, breakdown, outro) is labelled for you.
Live playback
Click anywhere on the timeline to move the playhead and hear the mix in real time as you edit — no rendering step. The zoomed waveform follows the playhead.
Undo, redo, save sets
Undo and redo cover every edit, including marker drags. Sets save to a single file you can reopen later.
Export pack
Render the finished set to MP3 (128, 192, 256 or 320 kbps), FLAC, or a 44.1 kHz WAV (16 or 24-bit), with a cue sheet and an M3U playlist marking where each track starts.
Effects rack
Filter, echo, flanger, phaser, chorus, reverb, noise, roll, gate, brake, backspin, reverse and a three-band isolator. Add an effect at the playhead, then drag its edges to stretch it and its bar to move it — it snaps to bars, or goes free with Alt.
Effects on a single stem
Point any effect at the drums, bass, melody or vocals instead of the whole track: echo out only the vocals, filter only the bass. Whole-track effects then run over the result.
Sweeps with a start, an end and a turning point
Filters and noise move between a From and a To value across the region. Add a turning point and the sweep goes up (or down) and comes back to where it started.
Tails that ring out
Echo and reverb keep ringing after the track or the region ends, so an echo-out really does trail off, and Build and Release fade the effect in and out across its length.
Brake and backspin by speed
A fast backspin is a short region, a slow brake a long one: the Speed slider and the region's length are the same control, so there is never dead air.
Now playing, everywhere
Mixdis tells your computer which track is playing the same way Spotify does — through the Windows media session — so overlays and visual tools such as Trippin, and the Windows media controls, show the song name with nothing to set up.
Grid markers
Pin a beat and drag it: the grid stretches between markers and only shifts outside them, so a drifting track can be corrected without slipping the whole grid.
Drag and drop
Drop audio files onto the set list to insert them at that position, or onto the mix timeline to insert them where you drop.
A layout that fits
The timeline fills its pane with as many track rows as will fit, tracks wrap onto the next row, and every split bar is draggable.
Mashup mode
A toolbar toggle swaps the set builder for a multi-lane, bar-grid timeline and back again. Your set stays exactly as you left it; mashups save as their own files.
Whole songs, cut anywhere
Drop a whole track on a lane, press S to split it at the playhead or Shift+S to cut every lane at once, then drag the pieces to rearrange. Edges trim, Ctrl+D duplicates, and everything snaps to the bar, the beat or nothing.
Any stem, any song, any lane
Each stem of each song can sit on its own lane. The All button drops all four stems together as a group that moves, trims and cuts as one — or take just the vocals of one track over the drums of another.
Tempo locked, key optional
Every clip is stretched onto the project tempo bar by bar, following the track's own beat map, with pitch preserved. A Key menu matches every track to the one you choose, and any clip can be shifted by semitones.
Instant edits, live
Stretched audio is cached in eight-bar chunks, so a cut, move or trim re-stretches nothing: scrub the ruler and rearrange while it plays. Only a tempo or key change has to be recomputed.
Effects that follow the clip
The whole effects rack works on lanes or the master. An effect placed on a clip moves, cuts and duplicates with it; drag one onto a lane and a preview shows where it will land and whether it will follow the clip underneath.
Full-quality stems on import
Each track shows a progress bar while its neural stems are separated, and the mashup switches to them automatically when they are ready, so what you hear while arranging is what you export.
Export, save, open recent
Export the finished mashup, effects included, to MP3, FLAC or WAV. Mashups save and reopen as files, with an Open recent list of the last five — in the Set menu too — and right-click menus on clips, effects and lanes.
