A real quick reply:
zmix: I have attached a sample of a TR-808 clave run through an IR generated by Alelsey Vaneev's Voxengo Impulse Modeler; I took the "Hall 2" preset and minimized the decay caused by air to get a reverb time around 10 seconds. It's not nearly as precise as a Lexicon to program; there is no "reverb time" setting.
What I had to do is modify the absorption properties of the walls and the air ("air" would be more adsorbent when, for example, simulating a concert hall full of people), test out the reverb until I got about a 10 second decay time, spend 20 to 30 minutes doing a final 1,000,000 ray "render" of the hall, then applying the generated IR on a clave sound.
I'll let people decide for themselves which sound they prefer. The clave going through the 224 concert hall, and the way it flutters at the beginning, reminds me of Vangelis doing the same thing in his 1983 classic "Antarctica", where he took the clap of a drum machine and ran it through the 224's Concert Hall with the decay at the maximum time and the same flutter at the beginning of the reverberant wash.
I could have given the sound more flutter or a slower build-up by moving the virtual microphones around and increasing the size of the virtual hall (the program can do a hall up to 75 meters on each side; this virtual hall was about 30 meters wide).
Sean: Thanks a lot for the pointers. I will download these articles and read them on my flight tomorrow. It gives me something good and worthwhile to read.
