Hi all,

I can't set my external audio interface to work with FLX4/RB/Serato

it's properly recognized but it's not separating room/headphones audio properly.

I'm able to set channels 1&2 to master out and channels 3&4 to headphones but it's like all channels are mixed so i can't use headphones cue properly (its also being heard on master out)

I use the same audio interface with a S2 mk3 traktor controller and it works like it should.

Hope you can help,

Thanks, 
Nicolás
