Some problems with XDJ-RX as a Midi controller

Hi Guys,

Yesterday, I tried to play with my XDJ RX as a midi controller for Ableton live, the mapping was fine, but I noticed the following issues while I tried to set everything up:

1- If you connect the USB cable to the PC and switch on the XDJ RX as mentioned on the operation manual, the device freeze without booting in.

2- After mapping the knobs, it takes sometime for Ableton live to retrieve the full midi mapping parameter of the knob and make it available for the assigned software feature/ volume controller.

3- I couldn't find the XDJ RX under the Audio interfaces in Ableton live, so respectively, I couldn't make it work as a playback device.

Other thing I discovered while playing with the device as a standalone, when the Sync feature is enabled, the tracks tempo controller doesn't functioning at all, that's mean even if I switch off the Sync feature it doesn't allow me to control the speed of the track which make it hard to change the tempo of the mixing on the go. I'm not expecting to play an entire mix (EDM) on a specific tempo as we usually go from slow tempo to fast tempo and keep slowing down in between to give the audience time for a break. The only way I found it possible to change the tempo of the synced track is by pressing on the previous track search to start it all over again, but this is not handy at all from my point of view.

Thanks,
