Thanks, everyone, for your help. That did the trick. EVerything worked last night at rehearsal. Yes, the idea that the reverb (and delay) is a master AND post-fader on the mains (LR) had escaped me. So, since this is a FAQ:
**** To get reverb working on ANY output, you must have the fader UP in the mains (LR) output (or your AUXs won't get anything).
You guys are the best!
