Melville Clark Piano Plays Five Roll Formats
By C. Jim Cook
In the 030110 MMDigest, Jim Welty spoke of a Melville Clark player
piano capable of playing any of five different roll formats. Okay,
I've never seen one of these, so I'll ask:
1. What were the five different formats?
2. How do these work?
I assume it's a tracker bar with five different sets of horizontal holes?
But how is only one set selected? (How is it implemented: internally?)
3. Is it practical to retrofit an existing player piano to play these
five formats, assuming that the parts are available?
