I really hate to even comment because everything that needs to be said has been. There is great solid advise here on this thread. Possibly a bit confusing as there is a few different ways explained. So I will try to keep my advise short.
When I set up to do vocals:
-Turn off all other track FX (Delays, reverbs, Chorus, EX) Okay to keep Guitar Sim FX.
-Insert the Sonitus Reverb directly in to the FX bin (no need to worry about saving resources we are not using a 1985 Texas instruments computer)
- Control the level of reverb from within the Sonitus plug in.
- Set your tracks Input to your Audio interfaces Microphone Input
- Set your tracks output to Master bus (or Vocal bus if you have one).
- Once this is complete, Right click on this track and choose "Save as Track Template".
This Track Template will now be your custom Reverb/Vocal track for all future Projects.
If you are experiencing and delays in signal I suspect your Latency is coming from your AI and buffer settings should be adjusted.
I sometimes use another method which entails creating a VOX bus and routing tracks outputs there.
But I prefer the Reverb in the FX bin as each track can have independent amounts of reverb.
For example: I like more reverb on the track I am recording, but less reverb on already established Vocal tracks.
Once tracking is complete, I delete the Reverb FX from the vocal FX bins and begin the Mixdown process by using VOX buses and Reverb Bus sends.
