I cover the operation of those circuits in my synth circuit classes:

see the video for Session 11 here: http://users.ece.gatech.edu/~lanterma/ems

and the video for 2/15 here: http://users.ece.gatech.edu/~lanterma/ece4803

I've also given it as homework. ;)

See Problem 1 here: http://users.ece.gatech.edu/~lanterma/ece4803/homework/hw3_06.html

and Problem 5 here: http://users.ece.gatech.edu/~lanterma/ems/hw2_08.html

I have a revised PCB layout on the timbre circuit from the Easel  
that's about half built, waiting for me to have time to test it. I'm  
hoping to get it over Thanksgiving break, maybe.
