Hmmm. This is a very good point. I guess the 'Z should be reserved
more for "overall" questions... like general sounds of chords of certain
tunings, as in the Dan Sterns example in the "lab..." I can see there
are some significant limitations when considering "beating" effects.
Manuel op de Coul had mentioned something similar some time ago
regarding some of the experiments...

Well, I did see the CSOUND page, references and, in fact, it looks like
the whole thing can be downloaded from the public domain and run on a
home PC... I wonder what kind of results one could get with just that
equipment??

It looks like a descendent of "Music 4" which, actually, I did have some
experience with back in the Paleolithic age... big mainframe,
punchcards, and we had to drive all the way to Oberlin to hear our
files-- no digital to analog converters around at that time. The
result?? 10 seconds of a couple of delicious "bleeps." Things have
obviously progressed since then!

I think, though, that I won't be able to master CSOUND by the end of the
week... so if anyone is inclined to try their hand at programming the
Paul Erlich files, I would love to hear the results!!!

If you're going to play with CSound, I *highly* recommend buying "The CSound
Book" from MIT Press. It has *two* CDs and includes CSound, a number of
tutorials, oodles of sample code and some student compositions. Yes, the
learning curve is a bit steep, but if you're at all good at
edit-compile-debug cycles in any other programming context, you should pick
up enough to do what you want. One other piece of software I recommend is
"Silence", which also includes CSound. The URL for this is

Joe,

Please send me the info regarding the Erlich experiment and I will program
the csound orchestra and score to do it. I will comment it so that you can
understand how it works, and generate the mp3 file for upload to the tuning
lab. Should be interesting to compare it to the results from the 'z. Is
there anything specific I need to know when I encode the MP3

Darren

If you like, I can create .wav files of these chords using Matlab, and throw
in some JI chords to boot.
