Real playback under the planning surface
Time-stretched playback, Master Tempo, EQ, filters, loops, beat FX, and scratch let you feel whether a transition works while you are still planning.
Connect a controller with a built-in mapping, or map your own MIDI controller. Rehearse with cues, loops, effects, headphone cueing, and an audio route that fits your hardware.

Plug in a controller with a built-in mapping, or map your own MIDI hardware in Ora DJ.
Built-in mappings cover eleven Pioneer DJ, AlphaTheta, and Numark models. Plug one in and start playing.
Using something else? Move or press each control when prompted, then save the custom mapping for next time.
You will feel at home immediately. Test your transitions, arrange your tracks, make it flow.
Everything you would expect from a controller is supported.
Time-stretched playback, Master Tempo, EQ, filters, loops, beat FX, and scratch let you feel whether a transition works while you are still planning.
Eleven Pioneer DJ, AlphaTheta, and Numark controllers have built-in mappings. For other hardware, map any MIDI controller and save the layout for next time.
Controllers
Eleven Pioneer DJ, AlphaTheta, and Numark controllers have built-in mappings. If yours is not listed, Ora DJ walks you through a MIDI mapping one control at a time and saves it for the next session.
Built-in mappings
Performance controls
The deck and mixer support the parts of a transition that need more than a play button.
Save a loop as a cue and return to it, or set an auto loop by beat length while the deck is playing.
Assign separate stereo output pairs to Master, Headphones/Cue, and Booth. Ora DJ remembers the routing for each audio device. Separate cue and booth pairs need a device with enough outputs.
Send the master deck tempo to a hardware synth or drum machine through a MIDI output on macOS. Start or re-sync its sequence on the next bar.
Effects
Route regular FX to a deck channel or the master. The mixer also has five channel effects controlled from the channel FX knob.
Keyboard
Deck A sits on the bare keys and Deck B is one Shift away: hot cues on the number row, loops under your right hand, play on Space. Hold a modifier to see its layer. Remap any key and save the layout as a profile, or switch to a Rekordbox-style layout.
No modifier · 32 keys
Hold Shift, or press any key
Click the map, then press keys. This is the default layout on a Mac keyboard.
Use a built-in controller mapping or map your own MIDI controller, then test transitions while the set is still taking shape.
