31 + 19

Jon Catler's JOINT performed on the AFMM concerts 2 years ago "jointed"
together 31-ET and 19-ET. It was most successful and was featured on New
Sounds with John Schaffer (WNYC-FM). It featured Jon on fretless guitar
(playing in 31-ET), Neil Haverstick (playing 19-ET fretted), David Eggar,
cello, Guy Tyler, string bass, and I played bassoon. The work is
improvisational based on themes. Very powerful!

I did some WEB browsing yesterday and discovered that there is
a 30 minutes VHS video of Cris Forster performing on his unique
set of custom-built instruments in JI. Cris played in the Partch
Ensemble and has constructed a an orchestra of instruments
according to his own designs. Among these are the Chrysalis,
a large rotating, circular harmonic canon, and several tuned
percussion instruments. See XH 7&8 for color pictures and
description.

Anyway, the video "Music Wood Steel & Glass" is available from
Richard Gaikowsky, One Way Media 1035 Guerrero, San Francisco
94110. The URL is http://www.slip.net/~richgaik/cris.html.
I haven't seen it, but it sounds very interesting.

I think a great program of tuning videos might consist of this, Partch's
"Dreamer ," and the Lou Harrison video (which, alas, I haven't seen
either).

I also came accross Arnold Dreyblatt's "Animal Magnetism" in JI.
described at http://kochint.com/Tzadik.html.

Brian asked me to post a question about CD-ROM generating software
for a proposed intonation disk. Is there a greater need for MAC or PC
compatible CD-ROMs and is there any way to convert one format to
another without having to completely do the CD over? (I'm not sure
I understand the problem well enough to be asking the right question.)

I got email from a Thomas J. Burh at SonicArtz Software concerning
microtonal notation for a software project his company is doing.
I referred him to Paul Rapoport (and LYME) and suggested he join the
list and read the archives. Any other suggestions? His email address is
insiders@MTS.Net.

It all depends on the type of information, but, yes, there are ways to make
a CD-ROM readable for both Mac and PC users. Of course, if you're putting
software on the disc, then you have to decide on Mac or DOS (though both
can fit on the same disc -- see below). Likewise if the format of the
documents are particular to one operating system (such as files that have a
Mac resource fork), then the disc (or volume) has to be OS-specific.

However, if you are putting raw sound files or text files that are readable
by either system, then the most straight-forward method is to use the ISO
9660 standard, a kind of "bare-bones" structure that is readable from both
Mac and PC, but lacks the nice amenities provided by Mac HFS directories,
such as long file names, spaces within file names, and icons. Commercial
CDs rarely use ISO 9660 nowadays. High Sierra format is similar.

Another method would be to split your disc into Mac and DOS halves, or
volumes. Such a "hybrid" disc would have all the advantages of the
OS-specific directories. The down side is that you would essentially halve
the amount of space you have.

However, I have heard of people who have had separate Mac/DOS volumes for
their OS-specific stuff, and then a third volume with the raw data
accessible to either. Thus your Mac software would be on one volume, your
PC software on another volume, but both would use the same sound files and
raw text files that take up the most space on the disc. I haven't seen such
a disc, but it sounds like a good idea.

Of course, both Mac and PC should be able to read CD-audio ("Red Book"
audio) off a CD quite apart from the computer data.

While all CD-R software should be able to write ISO-9660 and Red Book audio
their ability to write hybrid discs may vary. These issues are discussed
widely in the cd-publication mailing list (sorry, I don't have the address
handy).
