Larry,

   The MIDI to roll/book template converter is "commercial" software.
Sorry but too much work went into it to give it away.  David Wasson
handles sales and customer service issues.  For that, please contact
him directly at 619-481-1663.

   The program can read both type 0 and type 1 MIDI files.  It runs
under DOS and expects output in Epson 9-pin format, although we've
demonstrated that Epson 24 pin printers work well too without program
modification.  The program reads a configuration file which tells
what MIDI events are to be associated with which tracker bar/book reader
position.  There are specifications in the configuration file for almost
every imaginable tracker bar/book reader idiosyncrasy such that it is
possible to take a MIDI file which has been edited and playend on a
synthesizer and have it produce a correct perforation template without
further processing for an instrument which requires special handling for
percussion, etc.  Note that many band organs trigger percussion on the
end of the hole, and the hole has to end "early".

   I'm considering a Windows implementation since the program ties
up the computer completely while printing under DOS.  For the
techies:  the program started its life running under the Unix OS and
drove an ancient Apple Imagewriter.  I do almost all of my initial
development on Unix.  "Porting" working Unix programs back to DOS can be
somewhat aggrivating, but most people do not have a Unix workstation to
run this kind of stuff on.  The program is modular enough that I'm
hoping someday to have a chance to drive other output devices besides
a printer.  A CO2 laser would be my favorite...    An Numerically Controlled
machine tool would be second on my list.

   With all of that said, I don't want to discourage our readers from
experimenting with their own projects.  One of our readers indicated
a while ago that he'd printed roll templates with _WORDS_.  I'm sorry,
I don't remember any more who that was.  There's lots to be done by the
hobbiest.  Later in this evening's digest Bill Jelen suggests using an
inkjet printer for printing words on rolls.   A laser, an ink squirter,
a little machining, a little programing, and a LOT of marketing to pay
for it all.  It would be fun...
