One window, three ways to use it.

Browse, listen, mix. The same library feeds all three, and nothing is copied or imported twice.

  1. Library

    A cover gallery above the track list, BPM and Camelot key on every row, and an Up Next queue you reorder by dragging.

    Library view with the cover gallery, the track list, BPM, key and deck A / B buttons
  2. Player

    BPM and key in green readouts, a mini-waveform as the progress bar, shuffle and repeat, and the actual output quality always in the header.

Bit-perfect, and verified.

The app sets your sound card to each track's sample rate and sends the samples as they are: no conversion, no software volume. When the chain isn't clean, it tells you why.

A real mixer.

Two decks with tempo and phase SYNC, keylock, 8 hot cues, 1 to 16-beat loops locked to the grid, a 3-band EQ with KILL, and headphone cueing on a second output. Load a track on A or B from the library and it waits, paused. Click a deck's key and the other deck's track picker shows only compatible keys.

From listening to mixing, without a gap.

Switch to the DJ Mixer while a track is playing. It keeps going on deck A or B, at the same position, and you pick the next one. The way back works too.

Library

Same track, same position. No reload, no silence.

Built around the signal.

Three parts of the app that most players leave out, shown as they work.

Color waveform

Lows, mids and highs each have their own color, so a track's structure reads at a glance. Serato or VirtualDJ style, your choice in Settings.

  • Low
  • Mid
  • High

The smaller tools you'll use every week, in four groups.

Up Next queue
Play a track next or add it to the end, reorder by dragging, save the whole queue as a playlist. Played tracks stay in it, greyed, until you clear them.
Shuffle & repeat
Shuffle plays the whole list once before repeating. Repeat the list or a single track.
ReplayGain
EBU R128 at −14 LUFS. Off by default in the player, and the header says when it's on.
