I tried this with the Bovenkirk and Metz, for no particular reason — maybe I was bored that day — as an experiment to make it a bit less wet, and really didn't like the result at all. It just sounded "odd".
This is where surround sound sets really shine. You can route the long reverb to the back speakers which offsets the reverb truncation in the front speakers. For a couple of my favorite Surround Sound sets, I've taken time to find the right formula. For the front or close samples of a SS set, I start with loading only a Diapason chorus and try different short decay settings. Loading only 3 or 4 ranks makes the subsequent Cache rebuilds time efficient. I try to find a setting that has the least abrupt reverb cut off. Since my middle speakers will have the Nave or Near samples routed to them, it softens the cut off from the Front set. Yes, I do the same truncation experiment for these mid samples to have the reverb tail be a little longer than the Front sets. The rear (surround sound) speakers are course get the full release. The result is sound flowing from front to rear! This varies per sample set. Looking at my notes, for the Armley-Schulze, the formula is:
Chancel (Front) 720ms
Nave (Middle) 1.5seconds
Surround (Far) Full release
BTW, there are a few exceptions; for a couple of reeds in the Chancel, I gave them the 1.5seconds for reverb as the truncation sounded odd. That discovery came after playing it for awhile. Also, the volume for each surround division is important too, the Chancel being the loudest. The whole concept is to have the articulation of a dry set in the front, some reflections in the Mids, and full reflections in the back.
For my "
maybe I was bored that day" experiment I tried creating a "poor man's" surround sound in Hauptwerk V by taking a dry or moist set and routing the same stereo signal to the back speakers with a generous amount of a large convulsion reverb model. It didn't sound natural at all
but more contrived. To be honest it was a quick test. I realize I probably may need to add some additional reverb to the front set (and trim the back) so it has the flow I achieved with the true SS editions. Has anyone else tried doing this?
