{...} What I have found is the only way to record the effects is to send them out of a physical output - a bus mix assigned to an xlr or an aux out - and then bring them back in to an input with a cable. The SD card only sees what the console considers inputs, not channels. {...}
Good news: I think I may have found a definitive, in-the-box answer for recording FX returns. Bad news: you probably aren't going to like it...
What I've come up with is "old-school". The FX returns may not show up on the "User" routing pages, but they
do still show up on the Ultranet routing page. So:
- Set "Card Outputs" 25-32 to source from "Ultranet" 1-8
- Set Ultranet 1 & 2 to source from "Direct Out FX" 1L & 1R (probably best to use a post-fade tap)
The FX1 returns will now record to the SD card (and show up in the USB interface) as channels 25 and 26.
Of course, you can go a step further if you don't want to burn 8 channels of recording inputs. Let's say you want FX1L and FX1R to show up on the recording as channels 31 and 32, but you still want to have recording channels 25-30 be inputs as normal:
- Set "Card" "Outputs 25-32" to source from "User Out" 1-8
- Set "User Out" "Output 1" through "Output 6" to source from whatever was originally serving as inputs 25-30 (i.e. "Local"/AES50-A"/"AES50-B")
- Set "User Out" "Output 7" & "Output 8" to source from "Ultranet" 1 & 2
- Set "Ultranet" 1 & 2 to source from "Direct Out FX" 1L & 1R (probably best to use a post-fade tap)
Which is...pretty ugly, but it should work without needing to use a cable.
