Hosts

Download the native app.

UDJ does not run in this tab. Builds land here when they exist — Mac, Windows, TestFlight, Play — not a WebMIDI mixer.

macOS

Columns / Rows / Grid, V10 exclusive audio, CDJ MIDI, Link pairing, set replay, Beat FX rack. No VJ pane on Mac.

Windows

WASAPI host with Link, Resolume VJ, and set replay. Same MIDI presets as Mac. No Beat FX rack yet — that one is Mac only. Not signed yet — read the note below before you run it.

iOS TestFlight

TestFlight not open

Phone plays off a rekordbox stick. A9 isolated pairs measured. This button becomes the invite.

Android

No Play listing yet

Compose host. Nothing is on the Play Store yet.

Running the Windows beta

Unzip it anywhere and open udj_windows.exe. Keep the mappings folder next to it — that is where the CDJ and DJM presets live, and the exe on its own starts with none of them.

Microsoft Code Signing — what lets UDJ open without a warning, and what it needs to go on the Windows Store — will be live once the business verification completes. Until then the first launch comes with a Windows warning. Click More info, then Run anyway. Ableton Link is not built on Windows; the Link pane is UDJ's own pairing.

Link on a host is a pairing page on the LAN after you start it (port 17999, four-digit code). That is a surface — no audio. It is not this website.
