Easy solution LongWave:
Get a reverb set up on a track exactly the way you want it, then bounce the result to disk, import it into your session, and mute the original. Do that with all the tracks and your processor will be able to sleep right through it.
Alternative, get more processing speed!!
I have Waves Gold and the TC plug-ins, use them both a lot, but I prefer the TC's for vocal set-ups. TC VoiceTools, for me, is the most valuable plug-in I've got (not just for vocals).
Be very carefull with using a DAW plus external outboard gear. It will (not might) give you a problem. Something even most "pro's" haven't figured out yet (especially in large studio's where they use Pro Tools plus a large console plus loads'a outboard gear).
Everytime you create an aux send, export a signal into an external processor and route it back into your system, you have a time delay on the return, which is called latency.
If you do the same within your DAW you will also create latency, depending one the plug-in it averages at between 7 and 12 samples. A good system will compensate for the latency in the return automatically (most don't), by creating an equal delay in all the session's tracks.
The only way to do the same when you route an aux outside your system is to measure the latency, and make adjustments. Very time consuming (if you know how to do it
. As you can imagine outboard gear creates a latency multiple times that of a plug-in.
Just imagine what a track sounds like if you have, lets say 20 tracks, and 12 of them are out of time somewhat!!n It sucks!!
(and there is one of the reasons why some pro's say digital recording sucks - they havn't figured out the problem ... yet)
