Hello, first of all here is my configuration: - Macbook w. OSX 10.4 - Firewire Audiophile - Traktor 3.3 - Vestax VMC 004XLu I used to play with a Vestax VCM 100 with the mixer internal in traktor and as I am progressively moving out to time coded, i have now the mixer and shall get the decks later on. In the meantime, i wanted to use the mixer as an external mixing tool to traktor 3.3. In the output routing of Traktor, i select channel 1 & 2 for the deck A and channel 3 & 4 for deck B. The Audiophile FW sound card has two stereo outputs, which are each plugged into a separate channel of the Vestax VMC004. The master 1 is then wired to the speakers. Once this is done, I have absolutely no sound coming out of traktor. I have checked that the proper sound card is selected in the preferences. I have checked that the routing of the soundcard is correct. I have checked that the cables are well connected etc ... I have checked that Itunes or any other computer sound will play throught the soundcard/mixer/speaker I have checked that in internal mixer its still working. It just doesnt make sense to me and I do not see what is wrong. It must be that big a thingy to click or switch that i cant see it ... Anybody could give me a little hand here ? Cheers Vinc'
