OK, I'm new to convolution reverbs, but I like the idea. I do understand that things are different --- for instance, as I understand it, there's already some pre-delay in the Impulse response, so you set things up a little differently.
When working with Room reverb, I usually set up a reverb FX bus and use it as a send. In fact, on Room Reverb, there are settings explicitly for this where the mix is 100% wet. I've tried this on the Open AIR 'verb, and when I set the mix to 100%, different impulses give very different results than I expected (different levels, etc.), to the point where I wonder if this is not the expected workflow for a convolution reverb.
Any thoughts? How do you use Open AIR (or other convolution reverbs)?
the interesting thing for me is I use it more as a sound design tool- you can completely reshape sounds using simply impulse responses you can download for free online. add filters to the mix and you can take a generic sound and create something unique you'd have never expected before.
