DDJ-400 no longer works

I wanted to use a new DDJ-400 with Djay Pro AI again and had to find out that many things don’t work anymore - neither with the integrated nor with my own configuration. The jogwheels are no longer usable, but can be reassigned in the mapping. But the knob to select the titles can no longer be used, it is no longer recognized by Djay Pro. What happened there? Is this due to Djay Pro or maybe it is a problem with the hardware of the controller? With Rekordbox on the MacBook, the controller is perfectly usable, so I don’t think the device is broken.

Are you on the latest update?

Just today I installed the latest version from the store. I haven’t had a DDJ-400 in use for the last few weeks, but about four weeks ago everything was working fine. Since then, I think there have been two updates to Djay Pro AI.

Were you messing around with the XML file for it?

No. And I don’t have any access to the integrated configuration, at least not on the iPad.
What irritates me the most is that the rotation of the library button is not registered and displayed at all, the corresponding midi note is not displayed in any case. The pressure on the button, on the other hand, is implemented directly.

Hi @Chris_R,

We’re sorry to hear that you’ve been having issues between your DDJ-400 and djay.

Have you tried as of recent to use an app like MIDI Monitor for Mac to confirm whether or not the DDJ-400 is behaving as intended in order to conclude whether or not this may be a software issue or a hardware one?

Additionally, can you think of any possible changes in your setup which could’ve caused these issues such as Mac updates, changes in cables, etc?

Happily awaiting your reply!

I tried Midi Monitor today and it doesn’t recognize me when I use the knob to navigate through the music library. So it might actually be a problem with the controller itself. On the other hand, it works fine with Rekordbox on the Mac.
I haven’t made any changes to the configuration other than a firmware update from 1.02 to 1.03. But even that was a few weeks ago, so I can’t say for sure if the problems occurred at the same time.
I think I’ll contact the dealer about this and try to get a replacement unit.
