Set up your sound

A club mixer (Rane Seventy) with Traktor

Follow these steps in order. The app's setup takes you through the same ones.

Your gear

Pick what you DJ on. Club mixer (with CDJs, turntables or a controller)

Playing vinyl? Plug your turntables into the mixer as usual: your partner hears your records through it. BPM, key and the shared waveform need digital players. Your partner comes in on one channel of your mixer, so a two-channel mixer leaves you one deck; with three or four channels you can mix between two decks.

Your mixer

On a Mac

Pick your model, so we can show you its steps. Rane Seventy

Not confirmed yet: we haven't checked which USB pairs this mixer uses.

  1. Install the Rane Control Panel from rane.com.
  2. Pick the pair your mixer sends its mix on.
  3. Turn your partner's deck's Deck Source knob to USB A (or B). That channel is your partner's fader.
  4. Plug your speakers into this computer or an audio interface, not the mixer's master out.
  5. At Your sound in and out, choose your Rane, the pair your mixer sends its mix on, the pair that plays on your partner's deck, and your speakers.

Connect your Mac to your stack

  • Powered speakers: run a cable from your Mac's output (or your audio interface's outputs) straight into the speakers.
  • An amp and speakers: run the same cable into the amp's input. The amp drives your speakers as usual.
  • Not from your mixer's master out: your Mac plays the right sound at every point of a handover. And not Bluetooth or AirPlay: they add too much delay.
  1. Learn your partner's channel fader, with your mixer's MIDI on. Pulled all the way down for 10 seconds after you've taken over, it tells your partner they can stop, the same as pressing Partner mixed out.

Your software

Pick the DJ software you play with. Traktor

  1. Pick Traktor, under DJ software.

In a set, you'll see these buttons and messages:

  • READY · Set starts in · Handover · Accept handover · Partner mixed out · Fader up
  • You have control. Press Partner mixed out when you're in; your partner can stop their track.
  • Handover complete. Keep your track playing until your partner mixes you out.
  • Your partner has mixed you out. You can stop your track now.
  • After you've taken over, pull your partner's fader all the way down for 10 seconds, and they're told they can stop: the same as pressing Partner mixed out.
  • Your partner's fader is down. Push it up before you Accept.

Your internet

Use a wired connection if you can: an Ethernet cable from your computer to your router. Wi-Fi drops out more often, and a dropout can be heard in the set.

Upload speed: 5 Mbps or more, or quality may drop. The app checks both uploads when you link. On a slower upload, that DJ's part of their partner's recording is at the live sound's quality. If a connection slows during the set, the full-quality recording needs time to finish after you leave, up to 15 minutes; anything it can't finish by then is at the live sound's quality.

How a set sounds depends on both DJs' internet connections, which we don't control. We can't promise a connection will be good enough, so try a short set together first.
