Recently I buy a Presonus Firebox and I try use with traktor and vci-100, but I don't know how to setup prelisten .
I have connect a firewire cable and 1&2 output to my amplifier how master.
In the traktor setup I have 1&2 outputs like master and 3&4 like monitor but only prelisten the up channel in the vci-100.
Sorry for my english...
Thank you.
