This note is in response to Robert Pintar's recent posting, asking for
help in understanding the Duo-Art mechanism.

It sounds to me like Robert is just getting started understand the
Duo-Art mechanism.  There is a great deal that is not understood, even
by people who have studied it for a very long time  I hope he  will be
able to quickly come up to speed and investigate the unsolved problems,
and not just cover well-trodden ground.

Robert, in response to your posting I have borrowed and scanned Duo-Art
Roll 6878, the second part of George Gershwin's "Rhapsody in Blue," and
I have reconstructed the master roll from the scan.  I think your
careful examination of this roll would answer many of your questions,
such as (for example) the relationship of snake-bite timing to note
timing.  If you will send me your e-mail address, I will be happy to
send you a copy of the master roll.

Welcome to the group.  I note that you work for Hewlett-Packard, and
that means that you have deep technical skills.  We are all looking
forward to your contribution.

Wayne Stahnke
