How to download

The One can be purchased from the One DJ web shop.

After purchasing One DJ, you will receive an email with the login and password for the Audio Artery License Manager and link to your downloads.


Download and install the License Manager. Use the login and password in the confirmation mail to log in.

If prompted, update the License Manager.

Click "INSTALL" to download and run One DJ installer. Click "Next" when prompted.

Click "Activate" in the License Manager to activate your software on your computer.

Connect your MIDI controller, if you wish to use one.

Run the One DJ software using the "Launch The One" button in the License Manager.

See License Manager manual for further instructions.

On the first startup you will be shown a wizard to choose the desired default MIDI controller and audio output. Be sure to check "Override existing settings". You can later run this wizard again from the general options.


Clip - A single audio file.

Track - A line in the player deck timeline on which clips can be dropped. The amount of available tracks is unlimited.

Timeline - A workspace in the player deck consisting of multiple tracks, clips and editing data.

Default Layout

Default layout consists of most basic elements of a DJ software - two player decks, mixer, browser and some effects. Other preset layouts can be found at the layout menu in the title bar.

Getting Started

1. Startup Wizard

Choose the default audio output and your MIDI controller using the startup wizard dialog window. You can always open the wizard again when running One DJ, so no permanent damage will be done, what ever you choose.

2. Loading and Playing Clips

Clips are loaded by dragging files from the browser to the player decks. One DJ automatically analyzes the clips for waveform and beat grid data on first load.

Play button begins and pauses the playback of the clip loaded in the player. When on pause, press “Cue” to set up cue point. You can then recall the cue position by clicking "Cue" while playing the clip.

Playing a Basic Gig

  1. Repeat "Getting Started" to load and play music in the other deck, too
  2. Sync
    Press the "Sync" button on a player deck to match the tempos of the playing tracks.
  3. Volume and EQ fade
    Gently slide the volume slider up from the deck 2. Use the mixer's EQ buttons (high, mid, low) to swap frequencies between player decks.

See Player Deck and Mixer manuals for further information.

Advanced Play - Making Edits

  1. Click on the player deck's Edit Mode
  2. Border out the unwanted parts of your clip
    Drag the vertical borders of the clip to line out the unwanted parts of the clip. Clips can be split into two by clicking the desired split position and choosing “Split Clip” from the context menu.
  3. Paste and Repeat
    Dragging clips around the timeline with a mouse while Alt key is held makes a copy of the clip.
  4. Loop
    Looping is done by dragging clips from the loop handles at the sides.
  5. Stretch and shrink the clip from the stretch handles. The stretch can be reset at any time from the clip context menu (click the clip area with the left mouse button).
  6. Add additional clips
    When in edit mode, adding drumloops, vocal clips or other material is done by dragging clips into the free tracks below previous clips in the deck.

See Timeline Edit manual for further information.

Creating Beat Grids

  1. Click on the player deck's Edit Mode
  2. Turn on the Grid Edit
    Grid Edit is activated by clicking the clip and choosing “Edit Grid...” from the context menu (left mouse button).
  3. Choose Measure tool and draw one beat (one fourth of a bar) on your track
  4. Scroll forward on your clip and check if the grid stays on the beats
  5. Scale the grid by dragging beat markers to match the waveform until the grid is accurate during the whole clip
  6. Exit the player's Edit Mode and resume playing with your fixed beat grid

See Beat Grids manual for further information.
