I'm a new user of MIXXX, for now under windows XP because there is no USB driver for my controller (I hope I'll be able to migrate to linux one day, if a USB driver appears), a Kontrol DJ 500 :

So...This morning, I tried last version of MIXXX, under windows XP, since now MIXXX 's got a learning feature for midi controllers.
The installation was made without any problem. Before starting with MIXXX, I launch Konverter ("switch" software to activate the controller), using the "no preset- hardware" option (instead of other presets for well known dj softwares).
Then I launched MIXXX, went to the audio setup, and easily configure my sound card for master and headphone (audigy with 2 separate stereo out). THen, I wen to the controllers menu, and happily discovered than the KDJ was correctly and directly recognized by MIXXX.

So, now since KDJ 500 MIXX presets are not available, I just launched the learning feature. It's very simple, the software asks us what control is used for each mixing typical basic features (pitch, crossfader, etc...) . You just have to manipulate each control on your KDJ :

Once you've done that, you can use MIXXX ! Of course, it's just a very basic setup (just basic mixer functions, CD-like seeking, etc...) but it's working out of box.
Tonight after work I'll try to go deeper in the software. There is a lot of things we can customize, like on other software (basically, the same things)
Especially for two things : the ASIO creative driver seems to not be recognized (so I use the less good standard windows driver), and the jog wheels, because the jog wheels works very similar to old CD dj plates for now.
I'll post the results, of course.
