Ok im am a bit confused. I got my MBP w/VDJ connected by a USB cable to my HD2500, which is connected to my X500 Mixer. I got the VDJ to work with the 2500, however, my mixer is doing pretty much nothing. What setting do I have to use to make use of my external mixer? I am using only the sound card in the 2500 and want to be able to use the mixer also. Is this even possible? Sorry for the crazy question. Thanks.
