If Im understanding correctly, what you are trying to accomplish is recording multiple sources simultaneously- so heres a scenario- you have, for instance, 4 mics, they are connected to individual channels on a mixer, such as a Mackie, Behringer, Soundcraft- whatever- The mixer needs to have one or both of the following- "channel inserts" or "sub groups"- heres what they do- the "channel inserts" are on each channel with a mic pre (xlr connection) and is basicly an output for that channel only- the subgroups are assignable and there are typically 4 or 8 of them- you can assign multiple mics to one output if that so meets your needs or one mic to each of the sub-outs- (note that sub groups are in addition to main outs so you could theoretically have 6 or 10 out puts- 4(8) subs and a left and a right). From the sub group or channel insert outputs a cable connects to a multi track sound card, such as the M-Audio Delta 44 or 1010- then in your software pick what input from the soundcard will go to each track- and record- thats is one of many possible scenarios and of course we all gotta work with what we got. that also doesnt include any other processors or effects that may be in the signal chain-
- I hope that is helpfull-
