I’ve just finished getting this setup working properly on Windows, so thought I’d share the configuration in case it saves someone else some time.

My setup

  • Windows PC

  • djay Pro

  • 2× Pioneer XDJ-1000MK2

  • Pioneer DJM-900NXS2

  • Powered USB hub

  • RCA from each XDJ to the DJM

Connections

USB:

PC → powered USB hub → both XDJ-1000MK2s

My DJM is also connected to the hub via USB, although the DJM USB/ASIO audio driver is not used for audio in this setup.

Audio:

Left XDJ RCA → DJM Channel 2 LINE
Right XDJ RCA → DJM Channel 3 LINE
DJM Master → speakers

djay Pro Audio Settings

Go to:

Settings → Audio Devices

Set:

Audio Driver: WASAPI
Mixer Mode: External
Deck 1: Speakers (XDJ-1000MK2)
Deck 2: Speakers (2 - XDJ-1000MK2)
Deck 3: None
Deck 4: None
Pre-Cueing: None

I’m using a 256-frame buffer. If you get crackling or dropouts, try 512.

Important: I initially tried the DJM-900NXS2 ASIO driver, but this caused problems in djay. WASAPI with each XDJ acting as its own audio output has been completely stable for me.

XDJ Control

Go to:

Settings → MIDI Devices

Both XDJ-1000MK2s should show the built-in mapping:

Pioneer XDJ-1000MK2 (built-in)

I didn’t change any of the MIDI mapping.

Assign one XDJ to Deck 1 and the other to Deck 2.

The following all work:

  • Browse and load tracks

  • Play/Cue

  • Jog wheels

  • Tempo sliders

  • Sync

  • Hot Cues

  • Loops

  • Beat Jump

  • Quantize

DJM Settings

Set:

Channel 2 input → LINE
Channel 3 input → LINE

The DJM then works as the actual hardware mixer, including:

  • Channel faders

  • EQ

  • Headphone CUE

  • Sound Color FX

  • Filter

  • Beat FX

For the bottom crossfader:

CH2 Crossfader Assign → A
CH3 Crossfader Assign → B

If either channel is set to THRU, the crossfader won’t affect it.

DVS

Go to:

Settings → DVS Setup

Turn:

Digital Vinyl Control → OFF

It isn’t required for this setup.

Power-up order

This has given me reliable USB detection every time:

  1. Powered USB hub ON

  2. PC ON

  3. Wait for Windows to fully load

  4. DJM-900NXS2 ON

  5. Both XDJ-1000MK2s ON

  6. Wait around 10–15 seconds

  7. Open djay Pro

  8. Speakers ON last

I tested a full shutdown and cold start afterwards and both XDJs reconnected correctly without changing any settings.

Final signal path

djay Deck 1 → Left XDJ → RCA → DJM CH2

djay Deck 2 → Right XDJ → RCA → DJM CH3

This gives you djay Pro for library/deck control while still using the DJM-900NXS2 as a proper external hardware mixer.

Hopefully this helps anyone trying to get the same combination running on Windows. It took a little trial and error, but once configured it works really nicely.

Small extra tip – “Right/Left deck protected” pop-up

If you get a message saying:

“Right deck protected”
or
“Left deck protected”

when trying to load a track, it’s caused by this setting:

Settings → General → Protect active deck

When this is ON, djay stops you from accidentally loading a new song onto a deck it thinks is currently active.

That’s useful as a safety feature, but if you’re using the XDJ-1000MK2s as proper hardware decks and find the warning annoying, you can simply turn:

Protect active deck → OFF

I’ve turned it off on my setup so loading tracks from the XDJs is quicker and behaves more like a normal standalone workflow.
