I am getting ready to mix a choral arrangement that consists of 32 vocal tracks. 11 of my children and grand-children, 3 tracks each. The tracks are 4 parts, SATB so I can put them anywhere in the stereo spectrum but am wondering how to get the fullest sound. Should I keep each of the parts together, sopranos, then altos etc? Or should I spread them all over the pan. They were all recorded dry, so I can add reverb to the final mix but with this many tracks, it's a bit difficult to use trial and error. I suspect high school chorus teachers group them by vocal part, simply so neighbors aren't distracting but does that produce the fullest sound? Any comments welcome. Thanks - Bill
