Bug Reports
1

A) SUMMARY OF ISSUE:

  • After formatting my computer and reinstalling Windows 11 and DJay Pro, my Pioneer DDJ-FLX6 controller stopped working.

    However, when I open and close Serato DJ Pro, DJay Pro works perfectly again.

    I’ve already tried different cables and USB ports.
    I don’t use a USB hub.

    The controller works perfectly with other software (Serato, Rekordbox, and Traktor).

  • Device model Acer ANV-15 41

  • Version of operating system Windows 11 26200.7705

  • Version of djay 5.6.1

  • Hardware/controllers used Pioneer DDJ-FLX6

  • Hardware firmware version 1.12

Hi @DJMarcky, welcome to the Community! Sorry to hear you’re experiencing this issue.

  1. Did you download the latest version of djay from the official Microsoft Store?
  2. Do you have an active djay Pro subscription and are you logged into your My djay account in the main settings page?

  3. When you say the FLX6 is not working with djay, what exactly is the problem?
  4. With the FLX6 connected to your laptop, can you please share screenshots of your djay Settings>Audio Devices and Settings>MIDI Devices?
  5. Please try installing the latest FLX6 for Windows again.

Hello! It’s been a week since my last reply. I’m going to consider this topic completed for now so I can focus on others. However, please feel free to respond and we can definitely revisit this. Thanks!

Actually, rather of being a hardware issue, this seems to be a Windows 11 driver handoff issue.

The fact that your DDJ-FLX6 begins operating in djay Pro as soon as Serato is opened or closed indicates to me that Serato is correctly initializing the ASIO driver whereas Djay isn’t. Djay can seize the driver stack after Serato “wakes it up.”

Windows occasionally installs a generic audio driver over the Pioneer one after a fresh Windows 11 installation (26200 releases in particular).

What I would attempt:

Remove the Pioneer DDJ-FLX6 driver entirely.

restart

Install the most recent official FLX6 Windows driver and firmware 1.12 again.

Make that the Pioneer ASIO driver is being used, not a generic USB audio device, by going to Device Manager → Sound, Video, and Game Controllers.

Additionally, choose the FLX6 ASIO driver by hand under djay > Audio Devices. Don’t use Windows audio by default.

It’s 99% driver initialization order if Serato solves it each time. If you lock that down, it should no longer occur.

I’ve also seen that Acer laptops’ USB power management sometimes cause issues. Just in case, turn off USB selective suspend.
