New driver for Xone:DB4

[Mischa85]

Hi all,

Recently I bought this great mixer. Apparently Ploytec, the manufacturer of the audio interface used, has not been keeping their drivers up to date. After blood, sweat and tears I was able to reverse engineer Ploytecs weird but clever PCM communication and cobble together a driver.

The driver is made for efficiency and allows for incredibly low latency (< 2 ms).

Currently only Linux, but now we have something working in open-source land I should be able to cobble something together for macOS and Windows, too.

For anyone interested, here’s the code:

Hi Mischa,

Have you managed to set up a driver for Windows as well? I’m running Windows 11 with Rekordbox. The Xone driver works but it’s not very stable. It’s a shame, because the mixer is still the best out there in my humble opinion.

Not yet. I spend a lot of time working on the Apple driver which is finally coming together.

The Windows API’s are far better documented, so will be fun to have a crack at a Windows driver too.

Holy Mischa!

This is great news! If this ends in a stable updated Windows driver I’d be willing to throw in a big cup of coffee with chocolate on top. I’m still running on Windows 10 to increase the chances to keep that old driver halfway stable. On my machine it reserves a constant portion on the cpu as soon as it is connected. So I have to give it quite a bit of Buffer headroom to avoid clicks and pops. Running okay with Virtual DJ which itself is pretty cpu friendly.

The DB4 is a forgotten masterpiece for which there are unfortunately very little chances to see similar concept bravery again in the DJ tech market these days. Everything has to look and feel club standard :/

Hi Mischa!

Thanks a lot for this, I’ve been waiting for this for years

This will help a lot of people!

The DB4 is one of the best mixers I have ever owned (and I’ve owned a few – some were crap }. To say it’s amazing is an understatement.
it’s downfall is the crap drivers.
Its great that someone has the time and patience to develop a new driver that might even fool Serato?
Look forward to trying it on Windows :-}
Many Thanks

Hello Friends, very excited to see work on potentially getting a driver for my good ol’ DB4! Any recent updates on the code for Mac?

Regards
