Pioneer PRO DJ LINK Not Detected

Supported Hardware

CueSync speaks PRO DJ LINK to:

• Players: CDJ-3000, CDJ-2000NXS2, CDJ-2000 Nexus, XDJ-XZ, XDJ-RX3
• Mixers: DJM-A9, DJM-V10, DJM-900NXS2, DJM-750MK2

On an older CDJ-2000 (non-Nexus) the protocol carries BPM but not hot cues or phrase data.

Network Setup

CueSync acts as a virtual CDJ on the same LAN as your rig. That means:

1. Your Mac and your CDJs / DJM must be on the same subnet (typically 169.254.x.x for direct ethernet, or whatever your router assigns via DHCP).
2. Plug your Mac directly into the DJM's LINK port, or through a gigabit network switch that also connects the CDJs.
3. Do not use Wi-Fi for the Mac — PRO DJ LINK requires wired ethernet for timing accuracy.

Common Failures

"No CDJs found on this network" on the Devices screen

1. Confirm the DJM shows LINK status on its front panel (green LED).
2. Each CDJ should display a player number (1–4) on its screen. If any shows "—" or "LINK" without a number, cycle its power.
3. Back in CueSync, open Settings → DJ Hardware: the connection status shows whether CueSync has joined the network, your virtual device identity, and the list of detected players. On Devices (Cmd+7) the header reads Scanning… and, after 60 seconds with nothing found, No CDJs found on this network. If nothing appears, the Mac isn't seeing the broadcast.

Packets arriving but beats don't register

Usually a subnet mismatch. Open System Settings → Network → the relevant adapter → Details → TCP/IP. Confirm the IPv4 address matches the 169.254.x.x range (or matches what your switch assigns). If your Mac is on a different subnet, CueSync receives the broadcasts but can't reply, so the handshake never completes.

Only one CDJ shows up

Some older firmware versions don't broadcast on the full link protocol. Update the CDJ to the latest firmware via Pioneer DJ's website. After the update, power-cycle the unit.

macOS firewall blocks incoming packets

System Settings → Network → Firewall → Firewall Options → confirm CueSync is listed and set to Allow incoming connections. If not, add it manually or turn the firewall off for the rig's local network.

Keeping the Beat Without the Link

If PRO DJ LINK won't come up, CueSync has other beat sources that need no deck connection:

1. Local Audio — open View → Local Audio and drag the night's tracks in. CueSync plays and analyses each file (beat grid, phrases, energy, key), so cue triggers and AutoPilot fire without a deck link (DJ and Production editions).
2. OS2L — with VirtualDJ (or Serato / rekordbox through an OS2L bridge) on a laptop, switch on Settings → DJ Hardware → OS2L (DJ software) → Accept beats from DJ software (off by default). It carries a beat grid only.
3. Tap tempo — on Pro Decks with no deck connected, tap TAP at least twice, then Start grid.

A Pioneer beat always wins: the moment the Link is back, CueSync hands the tempo back to the decks.

Still Stuck?

Contact support with:

• A screenshot of Settings → DJ Hardware (connection status and detected players).
• Your exact Pioneer hardware model numbers and firmware versions.
• Whether the rig works standalone (e.g., Master Tempo syncs between CDJs) without CueSync involved.
