Exact Scanning of Rolls
By Robbie Rhodes
Wayne Stahnke states that his goal is "exact scanning of the roll". I believe that the ultimate goal is more encompassing:
"The goal is to transcribe _all_ the data of the music roll
into a binary file, such that an exact replica can be made."
In order to "demonstrate that this goal can be achieved", one can produce (perforate) a music roll from the binary file, which may be compared with the original roll. Indeed, if this new "replica" is identical to the original, hole-for-hole and scallop-for-scallop, then that is _conclusive and complete_ proof that the copying process has recovered all of the data from the original roll. (Obviously, copying the printed lyrics and the fancy artwork are separate processes.)
If an exact replica of an original music roll can be made, then if follows logically that all the data of the Master Roll has been recovered, and one can truly declare: "This computer file is an exact copy of the Master Roll, and production rolls produced from this file will be identical in all respects to production rolls made decades ago."
Richard Tonnesen is equipped to produce music rolls from Stahnke's Master Roll files. If anyone has a supply of genuine Ampico paper from 1920, a "counterfeit roll" can be made which cannot be distinguished from an original.
You can't do any better than that!
