I think I did a posting on this a few years ago, but the excellent
link to the various formats is a good excuse to mention it again.
The Wurlitzer Style RJ residence organ roll was 12 inches wide,
105 notes, spaced 9 per inch exactly like an 88-note piano roll.

From the left, #1 is pedal octave keyer.  #2, 3, and 4 are Accomp.,
Solo, and Pedal stop pilots.  The next 12 channels are the bottom 12
of Pedal.  The octave keyer with any of these notes plays the second
octave of pedal.

Next is from Accompaniment manual, up 42 notes.  Then the Solo manual,
from G below Middle C up to the top C of the solo manual.  (This must
have given organists and arrangers fits!)

Finally, the last 4 notes control swell shutters (3 plus cancel,
1,2,3, 1+2, 1+3, 1+2+3, for 6 levels).  The very last hole is a trap
rail keyer, the only percussion hole in the scheme, by contrast with
so many orchestrion roll setups.

The three stop pilots convert the bottom 14 notes of accompaniment into
stop setting controls, lock and cancel style.  There is a separate row
of 14 holes above the accompaniment holes to accomplish this.  The
three pilot holes are displaced above the level of the other holes by
the same distance.   Any stop not set 'on' goes 'off' in an instant by
a pneumatic that is deliberately set to move a tiny bit more slowly.
There are less than 14 stops on the Pedal and more than 14 on the Solo,
so some of the Solo stops are on the Pedal pilot's 14 holes instead.
All a little strange.

Of the relatively small number of Style RJ rolls I have heard, almost
all have organists' names and sound hand played.  One, the second
movement of Dvorak's New World Symphony (the "Going Home" theme) sounds
hand played, but the organist listed is Frank Manning.  Dave Junchen
told me years ago that Frank Manning was a Wurlitzer factory tech and
listing his name may have been something of an inside joke, on what
might actually have been a drafting board roll.

On another topic, I would like to buy more serviceable plastic primary
unit valves still mounted on channeled boards with their associated
striker pneumatics, in restorable shape.  Recovering striker pneumatics
is no problem, but I would prefer plastic unit valves that can be sawed
open as necessary for recovering, especially if their guts were vile
Perflex.  Anyone?

Thanks, everyone, for all your postings, which I read faithfully every
day.
