Andy Taylor asked about music roll image editors that have a roll-like
display on the screen.  There are several such editors that I know of.
My knowledge is probably incomplete, and most likely not wholly accurate;
it has been relayed to me by third parties.  I hope other contributors to
the Digest will correct and expand on the information given here.  The
editors I know about are as follows:

   (1) "Wind" is a program created by Richard Brandle for music roll
editing.  It exists in two versions.  The original release was intended
for use with Macintosh computers; it had very limited distribution.  To
my knowledge, there are only three users other than the author.  A later
version, now complete or nearly so, uses Windows 95 as its platform.

   (2) QRS has an editor program whose author is unknown to me.  It is
intended for use with an Apple IIe, for internal use within QRS only.  A
few people outside QRS also have copies, primarily for creating original
material for use by QRS.

   (3) As Julian Dyer has pointed out, Rex Lawson created an editor for
his own use.  It also uses the Apple IIe as its platform.

   (4) Finally, I wrote "View," with which I intended to have identically
the appearance of an American-style piano roll (bass on the left, time
increasing from bottom to top, roll image scrolls down when playing).
The platform for View is any computer that supports Windows 3.1 or
Windows 95.

If any subscriber to the Digest knows of other editors, please let me
know.

 [ Editor's note:
 [
 [ I think Wayne's focus is on the problems unique to manufacturing
 [ punched paper music rolls, and so he is concerned with computer
 [ tools which can easily modify each hole, and the tiny web of
 [ paper between adjacent holes in a chain pattern.  The usual
 [ "piano roll image" displayed by a Midi file editor, such as
 [ Cakewalk or Master Tracks, is not well-suited for editing the
 [ isolated holes in perforator control files ("master rolls").
