Greetings, all.

I've been reading the digest since June 1, but have not posted
before. My interests run more toward pipe organs, theater organs
especially, but have found your discussions enlightening.

My father was a registered piano tuner and rebuilt countless
(non-player), mostly grand pianos. I grew up leveling keybeds,
adjusting actions, and so forth. He was only too glad to pay me
for doing tedious stuff (I was a mercenary little tyke). Of
course, if you're surrounded by pianos, you long to have an
organ instead. Go figure.  :)

At age 10 I owned a harmonium which I played (and dissected
regularly). There was usually a player piano in the house. In the
1950s there were still plenty of original ones that worked.

My career was spent working at IBM, servicing computers and their
predecessors, both hardware and software support. I've rebuilt
several player actions over the years, and done various work on
band organs, nickelodeons, and pipe organs.

I'm not a collector per se; I have an upright Brinkerhoff/Schultz
'Recordo' electric player which I rebuilt 15 yrs ago. Also a
Hammond B vintage 1938, and am installing a theatre pipe organ in
the basement. I'd love a Mills Violano, but it's out of my
league. Too bad so many of them became elegant liquor cabinets.

My hobbies 'converged' recently, when a friend showed me an organ
roll player he acquired, and wants to add it to the theatre organ
installed in his home. Seems the right time to say  "Hi... Help!"

Rolls are Duo-Art "Semi Automatic" (?). Holes are terrifyingly
small at 13 per inch. The tracker bar has 130 holes (I didn't
actually count them), and the paper measures 10-1/8" wide.

Registers are: (apparently)
61 notes solo
49 notes accompaniment
13 notes bass
rewind, and a few unused (?)

This format does not (seem to) include stop changes, and organ
registration suggestions and expression are printed on the roll.

* Was this the same roll used with the Hammond roll players? They
  appear to include Hammond drawbar/preset suggestions.
* Was this *the* generic organ roll?
* Did other 'standards' exist? (for organs with keyboards)
* Are any still cut/recut?

I've never encountered this genre of rolls, and hope someone here
can shed light on it (a tracker bar layout, perhaps?). In the
interim, I'll map it the best I can.

Just a rundown on the fate that awaits:

The roll frame itself was built (strike that... 'assembled') by
Aeolian-Skinner Organ Co out of Duo-Art parts (and seemingly
whatever else was hanging around). It's tubed to pouch primaries,
each simply operating a contact closure. In fairness to A.S., I'm
quite sure it's been 'reworked'. It's just not their workmanship.

This was removed from a pipe organ console, and is just the
player 'guts' with no cabinetry, screwed to a piece of plywood.
It all looks like a careless hobbiest's first attempt. No doubt
the console structure provided mounting for linkages and the
various components. They lacked the shame to provide an action
cutoff, and handled the consequences electrically. Meanwhile, the
pouches got lots of exercise.

A regulator feeds the action at one end, with the roll motor fed
from the action thru a tempo slide. There's no tempo bypass for
rewind, but they 'graciously' included a pneumatic to yank the
tempo lever wide open. There's a ventil to remove vacuum from the
entire unit, but if it had a motor-driven vacuum source, that
seems pointless. I think it was supposed to be the action cutoff.

There are many functions (like disabling the tracking device
during rewind) controlled by pipe organ chest magnets scattered
about. Oh, puh--leeze... (no action cutoff, remember?)

Ain't life Grand? ... "Here, Dave, build me something spectacular
from this box of junk!" (visions of the Phoenix rising from its
ashes) "Oh, thank you, thank you.... I'd be sooo delighted to."

Love it...  Should be fun. :)
