UDJ - Mix Your Way

UDJ is DJ performance software that puts up to eight decks on your iPhone or iPad.

Plug in a rekordbox-prepared USB drive and play your tracks with your own beat grids, hot cues, loops and waveforms. Or copy music into the UDJ folder in the Files app.

MIX
• 1 to 8 decks, laid out as Grid, Rows or Columns
• SYNC that snaps to the downbeat, and keeps the matched tempo when you release it
• Master tempo (keylock), Key Shift ±6 semitones and KEY SYNC
• Hot cues A–H, loops, beat jump, slip and reverse
• Beat FX on any deck or the master: echo, delay, reverb, flanger, phaser, roll and more
• A filter and 3-band EQ on every channel
• CHOP: tap a waveform to cut a channel or its low end

LIBRARY
• rekordbox USB drives and rekordbox XML, with playlists and search
• Beat grids, cue points and waveforms from rekordbox analysis
• MP3, AAC, FLAC, WAV and AIFF

HARDWARE
• MIDI controllers, with learn-to-map and ready-made mappings for popular players, mixers and controllers
• On a USB audio interface with 8 or more outputs, decks 1–4 each get their own output pair, so your mixer's channel faders and EQ work as usual

MORE SCREENS
• Link: a second phone or tablet joins over Wi-Fi as extra decks or a remote, by scanning a QR code
• 1 View and 2 View turn a phone into a portrait deck that stands in for a missing player
• Record a set's controls and replay it
