Mixlr streaming throught virtualdj with xdj-r1

in the mixlr interface, that report all outputs and loopback devices, native ASIO isn't displayed (additional info: asio4all is displayed but wont work with xdj-r1)
So, to try to make it work I installed virtual audio cable and used "advanced config" as following:
master: pionneer asio 1/2
head: pionneer asio 3/4
*master: vbaudio cable 1/2
*because I could'nt use the record loopback
-> it works but I have scratches in sound asa touch midi controler so it isn't usable ( guess it is 'cos of vbaudio cable driver do not use asio itself and can't manage to make it do it)

So I tried the WMD way, setting advanced config as following
master : pionneer speaker 1/2
head: pionneer speaker 3/4
master : vbaudio cable 1/2
-> suddenly the sound became very clear crystal, and the stream is recording well; but now in that config mode, with wmd driver, headphones channels (all) are linked to master output so I can't monitor anything than the master output.

so I need a fix for the headphone channel in wdm mode or perhaps a driver recoding is needed
