Ah... this ends up giving you the difference between the two channels.
Since I assume that the reverb processor does not send any signal equally
to both cannels, but different delays, it might be the same as the sum in
terms of volume, but with a different characteristic due to the changed
phase.

Lexicon and others create multichannel reverbs, but only for home, and
rather expensive, but that would probably the consequent way to go...
... and sounds familiar with "ambient", doesnt it? ;-)

No, I don't see any problem... I will try it, too!

Oh, I see... so you probably never have only reverb on the stereo set,
because all of the loops run on it, too, right?
But on the third speaker, you might get only reverb if you pan the loops to
center, is that how you use it?
