Chris,
In Jelani Eddington's book (which I discussed just a bit in the
thread addressed "to theatre organ users.....!", just below your
thread), he goes on through three pages, listing seven groups
of stops, to build through Soft Ensemble, Light Ensemble, Medium
Ensemble, Mezzo Forte, Full Organ, Full Organ plus Post Horn,
and last Full Organ with Post Horn Pizzicato, all of which I have
set-up on pistons for my Milan M-31. Jelani also includes the
famous "Hangnail" registration, attributed as created by George
Wright, and the infamous "Whorehouse" registration made so popular
by Tom Hazelton. This one uses no 16' ranks.
Jelai also list stops for each of ten Divisional Pistons for each of the
three manuals of the organ, as well as suggested Accompaniment and
Pedal registrations for appropriate use, all again with comments and
use suggestions.
I don't feel I should list the stops Jelani suggests in each step, he
probably views them as "proprietary" or at least copyrighted to him.
I suggest you buy his book, from which you almost certainly can
learn much as well as decide which of his suggested steps to "full organ"
you believe would not use too "many stops and crowding the sound...".
Certainly you can judge the sound from each step, and determine
for yourself by removing various stops to determine a full organ level
you like.
For each of the eight steps, he includes a few remarks about each
including why particular stops are used, for what sorts of music,
when Tibias ought and ought not be included, and when they
should be added, etc. Also whether the particular registration is
appropriate, or not, for use in chords, and ought to be reserved for
single note melody, etc.
Have fun.....
