[linux-audio-user] Question on mixer

Question on mixer setup. I'd like to begin recording to my pc, with a standard one input sound card. I'd like to do vocals and midi from my S90. To do the vocals though, I'd like the output of what's on the computer, and the output of what's coming from the S90, to go to the vocalist, but only be recording her vocals, not the whole main mix again. Do I need to get a mixer with sub groups so that I can play the entire mix through the main outputs and control outputs but only record her vocals? How do other people do this? The Behringer 1204-PRO seems like it might do what I want, but I thought I'd ask others opinion. Thanks! -- --- Allan Graves I came into this world with nothing, and I have most of it left.
