Reads the features of a copy as the tracker bar would read them.
Chains of holes on a position the bar does not read carry no symbol
and are dropped, which is what happens physically as well.
The bar is named rather than defaulted: a copy is read by its own
bar, and reading a green copy with the red one is a silent semitone.
Reading stops where the bar says the roll's content ends. What a
scanner punched past the rewind is not the roll speaking: Julian
Dyer's scan of the green 225 carries a staircase of test punches
across nearly every track after its rewind, which read on as symbols
would be 318 notes nobody played. The features stay on the copy,
since they are really on the paper and are his calibration of his own
scan; it is the reading that stops.
