Thanks, I'll take a look.  Probably overpowered for cutting paper,  though 
professionals would cut 16 copies at a time.
 
BTW, whoever said that a Duo-Art player contains two 4-bit D/A converters  
was right on the money.  An earlier German system, the Welte, used a pair  of 
analog integrators, also made from bellows.  Another US company, Ampico,  
combined the two systems, setting the playing level "digitally" Dan using the  
"analog" for smooth, human-like volume gradations.
