[David Roth Weiss] “BTW, a 5.1 mix out of FCS is actually doable these days using the 5.1 audio monitoring capabilities of the Matrox MXO2, five speakers, and a subwoofer, and mixing in STP,”
Don’t encourage such foolishness David! Minimum requirement for proper 5.1 mixing is a mixer that can sub bus 3 x 5.1 stems with full EQ & dynamics on those sub busses plus a final mix bus with foldown to stereo capability with proper monitoring. STP isn’t in that league and FCP doesn’t have sub bussing at all, let alone proper track based EQ & dynamics.
If anyone wants to try it, I not fly out and whoop them. They are going to whoop themselves anyway when they find out what a disaster they are wading into.
