I disagree, on two accounts.
1) There is nothing wrong with doing wet/dry blends with real/different acoustic
spaces...folks with reverb chambers have been doing it for years.
2) A proper impulse response is just the 'wet' component of the reverb. There
is no input signal present (i.e. the impulse itself is removed from the impulse
response) there is only reverb/reflections. You can use the wet/dry blend
to simulate how loud you make your room mics relative to your close mics.

With respect to RZ, this explanation of convolution is very different from
my personal experience. I have been using hardware and software convolution
reverbs since the Sony DRE-777 first came out... and Altiverb since it first
came out (the original hardware and original software). Both were designed
for, and work great in bus situations, as do all convolution verbs.
I also have GigaPulse. It is true that GigaPulse is designed to allow manipulation
of mic position (and other parameters) while keeping the input/output mix
fixed (as a recommended option with true acoustic spaces). In theory this
will give a consistent sound stage, and I like using it that way.
But:
This is certainly NOT an appropriate generalization to use when talking about
convolution reverbs.
Gene
PS The 777 still sounds great and can be found on eBay very cheap. It was
originally around $15K.
