I've completed the Active Essays that I'm using in my class on 
"Computer Music Implementation."  I've placed links to them and 
uploaded a 3.1a image containing all of them to:
http://minnow.cc.gatech.edu/squeak/1987

The first couple essays are better than the rest, because they've 
been improved based on the comments of John Maloney.

- For SqueakAudio list members, there are additional essays now on FM 
Synthesis, Subtractive Synthesis, MIDI, and Sampling that weren't 
there when I originally mentioned them.
- For other Squeak-dev-ers, you might be interested in the essays on 
FM Synthesis, MIDI, and Sampling because I walk through some of the 
Squeak sound classes and explain some of how they work.  The FM 
Synthesis essay, in particular, walks through several of the FMSound 
instruments, uses envelopes from the code level, then introduces the 
envelope editor.

There are a couple of other lecture slide sets on Csound and 
limitations of these forms of synthesis on the course Swiki, too, but 
these are in Power Point.  (Je77 Rick suggested that I link to them 
as "Inactive Essays" :-)
