I've been following the discussion regarding possible problems of
playing regular 88-note rolls on Ampico A and Bs. I'm a "newbie" to
expression pianos (this means that I hope some day to "trade-up" from
my regular pumper to a Duo-Art upright!). My question is: do Duo-Arts
have this problem with regular rolls also, or is this an Ampico-only
problem?

Regarding the Play-Rite discussion, I ordered some regular rolls thru
Playtime's homepage last week. I'll report on quality & sound when I
receive them. The Duo-Art roll (HMS Pinafore) that I've already
received sounds wonderful on my pumper. The roll edges are a little
rougher than QRS rolls (My one Keystone roll that has similar slightly
rough edges). The box is also a lighter weight cardstock than QRS, but
frankly, with a price difference of $3.25 between QRS and Play-Rite's
regular rolls, I don't mind this at all!

After playing new acquistions for first time, I always pump out my
tracker bar. New QRS rolls ALWAYS seem to leave little bits of paper in
the tracker pump filter. There was none with the Play-Rite roll--but
we'll see if that's just a fluke once I get my next shipment!
