Hi All,  In answer to Joel Cluskey's question, the Ampico system was
designed to be operated manually when using regular 88-note music
rolls.  However, as Robbie noted, the 'normal' playing volume can be
"permanently" pre-selected by activating the expression mechanism at
the very beginning of the roll.  The most desirable playing volume can
only be determined by the user, so I would suggest experimenting with
different levels before punching holes in all of the 88-note rolls.

It might be found that some music sounds best at a lower volume while
others sound better at a higher volume.

Musically,
