ddj flx4

Are you connecting to a USB-A or USB-C port on your computer?

Is the USB cable connected to the port with the computer symbol and not the one with the plug symbol?

Does the unit illuminate when connected?

Does the DDJ appear in the Windows Device Manager?

Has Windows automatically configured the FLX4 as the default audio device? If so, switch it back to your computer's internal sound card.

Are you using rekordbox 6.6.7, Serato DJ Lite 1.6.2 (or Pro 2.6.2, but requires that you have purchased a license or subscription) or newer?

Are you in Performance mode (rekordbox)?

If you open rekordbox > Preferences > Audio, does the FLX4 appear under Control Device Information at the bottom of the page?

Hi, i have the same issue. windows doesn't show that the device is connected. The device illuminates, but doesnt show up in audio devices. i connected it via type a to type c.

See above - can you provide the answers to those?

I connected type c to type a. Connected to the port that has the computer logo. Device illuminates when plugged in. The device does not appear in device manager. Windows has not set it as a default device. Using the latest rekordbox software. I am not in performance mode because it's hardware unlockable but it does not see the device. It does not appear in rekordbox preferences audio

I'm using usb-A for type -c
I tried several cables, on all 5 USB connections on the computer.
My previous controller ddj-400 works fine.

I'm using rekordbox performance mode

@Marin: "The device does not appear in device manager."

That could be because you're using the USB-A to C cable and it's not getting the required power. Please try using a USB-C to C cable for your computer, or if you don't have a USB-C port on your computer, use a USB-C to C table connected to a USB-C power adapter to provide power to the DDJ in addition to the USB-C to A cable connected to your computer for data.

@Joao > You're not using rekordbox 6.6.8; please update.

Still not working

I can only have control on ddj flx4 by disconnecting the usb cable and reconnecting it with the computer on.

However in the computers device maneger, the ddj flx4 is not recognized, but in the rekorbox audio i already have ddj flx4
