In response to Bob Pinsker's post on the Johnson and Waller hand-played
rolls, the "Marking Piano" and its companion carbon-marking console
that recorded those rolls at QRS is now on exhibit at the Musical
Instrument Museum (MIM) in Phoenix.  Quite an instrument.  See
http://files.asme.org/ASMEORG/Communities/History/Landmarks/5630.pdf 
for an article about it.

Also, Grant Chapman mentioned the Mechanical Gallery at MIM.  In
addition to mechanical musical instruments on exhibit, MIM has (on loan
from QRS) the machinery on which J. Lawrence Cook arranged rolls
(exhibit installation in progress).  For more info on MIM please visit

 [ Christina is Assistant Curator of Western Musical Instruments
 [ at MIM.  Her doctoral dissertation is entitled "Competing with
 [ Cremona: Innovation and Tradition in Violin Making in Paris
 [ (1802-1851)."  Her research illuminates how a historicist tendency
 [ and commercial demands in Restoration France worked together to
 [ undervalue French innovative violin-making designs and entrench
 [ Cremonese violins in the top position within a violin-making
 [ hierarchy.  (In other words, Antonio Stradivari wasn't the only
 [ good fiddle maker in Europe!)
 [
 [ She says about her job at MIM, "All of my experiences have led me
 [ to the Musical Instrument Museum, where visitors will not only hear
 [ but also see the instruments being played in their cultural context.
 [ It's about time!"
