XDJ XZ SOUNDCARD

Hello, 

I own a new XDJ-XZ and i tried everything on it. 

I noticed that something is going wrong when you want to record on multi-channel with another software like Audacity or Live.

The thing is : 8 mono channels are available for recording while choosing the "XDJ-XZ" on the preferences but only the channel one is recoding separately from the master. While I would have each channel separately.

My question is : Is it possible to record separately because the channels are available ? 

Also, after choosing on audio preferences from the mac "XDJ-XZ" as a soundcard it's impossible to broadcast music straight from the laptop.
