I see the entire problem.
You're routing is a bit off.
Try this.
1. Create your Connection audio track.
2. Create your radio FX audio track.
3. On your Connections track, interact with sends A/F.
4. On Send A, VO+Space on the top up, and go down to new track. Be
careful here. Not the track sub menu. It's below that. It will literally
say "New Track". This will force ProTools to create the AUX track for
you, with all routing set correctly.
5. Now, go to your Radio FX track. We're almost going to do the same
thing here, but not quite. You now have already set an AUX track, so
interact again with sends A/F, only this time, again, now, we're on the
radio FX track, not the connectionstrack.
6. On Send A of the Radio FX track, go into the popup for send A. This
time, instead of going to new track, go to the tracks sub menu, then
find the AUX track you created in the previous steps. Now, things should
be routed.
7. Now, go rename the AUX track to something more recognizable: "Group FX"
8. Finally, go to the AUX track, and interact with inserts, not sends,
but inserts, A-F. On insert A, instantiate your reverb. We're doing this
on the AUX track, not your two audio tracks. Beware.
There. Now play it back. You should definitely hear the reverb, if you
did this correctly.
On another note for the list entirely, given that he's naming that 3rd
track, "Group FX" it sounds like he's just trying to group both the
audio tracks into one, so he can instantiate reverb across both at the
same time. I could be wrong, so Danny, let us know if I'm incorrect on
this theory.
If that is the case, would it not be easier for him to create an
edit/mix group, then assign both of those audio tracks to that group,
then just apply the reverb to the group? The only thing I could think
that may not work for that method is the fact, if he does it as an
edit/mix group, wouldn't that mean he'd destructively have to print the
verb directly to the track with something like audiosuite? If so, then,
yeah, definitely not probably what he's looking for. I just thought
however I'd mention.
