It is the former! I'm very intrigued by all of the discussion that took place, even though some of it did go into the weeds, but that too was excellent food for thought.
I thought I'd take a moment to report back what we wound up doing last night.
The setup now consists of a pair of monitors above and to the right of the console, and another pair above and to the left. A third pair of monitors is across the room, and a subwoofer is on the floor to the left of the console.
1. I originally intended for the inboard two speakers in the front to be a pair for the Great and upper pedal division, and then send the lower pedal voices to the subwoofer on a separate channel. This didn't work out very well -- at least, I couldn't get it to -- so the left inboard monitor is daisy-chained to the subwoofer, which goes in channel 1 and is called "Left Main/Sub". The right inboard monitor is on channel 2, called "Right Main."
2. The left outboard monitor is channel 3, and is called "Left Outboard." All of the Choir goes here, with a few exceptions I'll note below. One such exception is the Gamba Celeste, which is routed to Left Main/Sub.
3. The right outboard monitor is channel 4, and is called "Right Outboard." All of the Swell goes here, with the exception of the string and flute celestes, which are in Right Main.
4. The two rear monitors are labeled Rear Top and Rear Bottom (they're stacked). From the choir, I've routed the Clarinet, French Horn and Orchestral Oboe to the top monitor, and the Tuba Mirabilis as well as the Trompette Festiva from the Great are routed to the Rear Bottom.
Early results are very, very good. Tutti can now be played without any distortion, and fairly loud! It could be much louder than needed without crackling. The entire organ now feels like the sound is hugging you as you play, and it's just marvelous.
Last night we ordered the Hereford Cathedral XL sample set, and will go through the requisite hoops this week to update the HW Advanced dongle and then install the organ. The routing will be very similar, except the entire Solo division on that organ will be routed to the rear speakers.
Thanks to each of you once again for your invaluable help!!
