Hello,  Having known people associated with The Aeolian Company (USA)
and the Wilcox & White Co. (also in Meriden, CT re the music rolls),
and friends of the Votey family, I can tell you that the expression
player is called: "Duo-Art" (phonetically), just as it's spelled:
"Duo" and "Art", meaning the 'performing' and 'interpretive' arts,
or rather, "semi-automatic" (since one must monitor the tempo on all
players) and "manual" (with the Pianola levers).

"Dew-Art" (DuArt) is a NY film processing Studio as well as a cabaret
program on the Nostalgia [cable] Channel: "Cafe' DuArt".

Of course, people who say "Dew-Art" and "Dual-Art" are often the same
ones who utter "Thermodist" (Themodist) and "reproducer" (reproducing)
-- the latter an Edison phonograph component.  These people often say
"Pumpers" for pedal players -- a term for an antique fire engine.

The lowest-of-the-low say "Snakebites" for the Themodist (solo) accent
holes of the Duo-Art Pianola, a recent term which should be discouraged
in my opinion.  (These same double-perforations operate Hupfeld's
Solodant, the Artrio-Angelus Molodant and a host of other players with
trade names for the same feature, of course.)

Usually, returning to the term "Duo-Art", most people from the era --
and once in the industry -- said "DUO-Art", putting the emphasis on the
first half of the combination word.

TV host Tom Snyder, by the way, said "DUO-Art" the other night on his
CBS broadcast.  You can read about it in my 'weekly' web site newsletter
called "The PIANOLA News":
