Hi Hetoreyn,
Interesting! The Todd AO Stage is the exact IR setting I'm considering for this stategy. However, it would be nice to have an A/B comparison.
This is what I'm imagining:
A: Altiverb instances only with the reverb knob turned beyond 100% to give it nice amount of tail something like 125% or more (i.e. "enough to simulate the produced sound just using Altiverb").
B: Same amount of Altiverb instances as test A, but with the reverb knob set to 100% or a little less (also, as I mentioned before...keep the tail engaged in your Altiverb instances). Then run that output through a "good" hardware reverb (or suitable plug-in) to add the extra bit of tail (i.e. "the produced sound").
Now, which would sound BETTER? Would there be a clear winner, or is it just a toss-up? If I could afford a Bricasti M7, I'm guessing that scenerio B is how I would use it with VSL.
