commercial synth circuits

[terry michaels]

Hi Debby, Gene

Thanks for the compliments on my VCO.  Not long ago I pulled the original
drawing for this circuit out of my file.  I hadn't seen it for a LONG time,
and I thought geez, this is a really simple design!

My current interest in reviving my work on analog synths is largely due to
my reading of Mark Vail's book last winter, a book your name appears in at
length.  Looks like you've had some interesting experiences with Moogs,
particularly Emerson's.  Want to trade jobs?

I first saw the Roland 700 at a Chicago NAMM show, and I remember being
impressed by that particular product.  I also remember visiting some booth
at NAMM, and being introduced to the designer for the company, and looking
at a schematic of their VCO, and it was nearly an exact copy of mine.  I'm
sure that guy read Electonotes.  I honestly can't remember if the VCO
design discussion happened at the Roland booth. or some other booth, as I
went to NAMM a number of years during the '70s.

Also at NAMM, I went into the Moog booth with a friend.  We went to a
corner where a modular system was set up and running, and Bob Moog was
standing a few feet away, talking to someone.  I started turning knobs on
the 960, and in a few minutes I had set it up to do a close approximation
to the ending riff from Karn Evil 9.  I started it running, and Bob turn
around with a smile and said something like "That sounds familiar"!
