The Computer Assisted Music Perforating Machine described by Robert
Hopp is almost identical to the machine I designed in 1979.  The
machine has been punching music for almost 17 years.  One of the
differences in my original design was the use of a proprietary music
encoding scheme, since MIDI had not been invented when I started.  The
computer was a Cromemco Z80 but is now a 486.

All of my files have been converted to MIDI, but at times I still use
the music editor that I wrote for the Z80 but have recompiled for the
486.  The other difference, is that I use a pneumatic driven punch.

 [ Editor's Note:
 [
 [ I've been hoping that perforating machines which were not tied to a
 [ specific "holes-per-inch" format would show up.  Now we know of two.
 [
 [ At least one of our subscribers has expressed an interest in building
 [ such a machine.  This should be good encouragement.
 [
 [ Ed, would you mind writing more about your machine ? There are a number
 [ of people here with oddball roll formats that would like to make single
 [ copies of things.  Do you do any "custom" perforating ?
 [
 [ Robert Hopp:  I look forward to hearing more about your system too.
 [ Do you do custom perforating ?  Is you machine in Germany ?
 [
 [ Do either of you plan on building, or building and selling more of
 [ these systems ?
