The Thomas Henry book

Anders & Larry,
	I have "The Elecronic Drum Cookbook" and really like it.  Tom goes over all
the little building blocks he's designed for simulating the various parts of
a drum sound (snares, stick strike, shell resonance, etc.).  At the end he
puts it all together to make a snare voice (I think) which looks a lot like
the ADV-Snare.  The only "special purpose" IC he uses is the fairly common
LM566 (oscillator).  I haven't had any time to play with the circuits, but
am looking forward to some experimenting some day...
	Larry, what did you think of the NE570 book?  I was thinking about getting
it too since I have a few of these things in my parts bin.


p.s.  John Simonton has a little circuit snippet on the Paia web page
showing how to add VC to the twin-T filter commonly used in drum circuits.

Well, there was more than one.  I have two of them:

"Electronic Music Circuits:  The Reprints" - a collection of 38 articles
from the pages of Polyphony, Electronic Musician, and others.  This one is
currently out of stock at Midwest Analog Products.  I'm not sure he plans
to re-stock it.  If he does not, it is a spiral bound book that could
easily be copied (with his permission, of course).

"Making Music with the NE570 Compander" - a short 18 page booklet with
circuits using this chip for VCAs, compressors, limiters, envelop
followers, etc.  This one is still available at the Midwest Analog Product

There is a third one I do not have called "The Electronic Drum Cookbook."
