Hail, new analog listmember (read...psycho...)

1.  Back a couple of decades ago, there were some people making analog
synth chips.  One was called Curtis.  The other Solid State Music.  Does
anyone know what happened to these guys?
Curtis Electromusic Specialties (CES) is long gone. There are still new old
stock chips out on the web, but prices are getting up there.
SSM (Solid State for Music) was gone for a while, but some of the devices have
been acquired by Analog Devices, but they are more generic types like analog
multipliers etc. Check Analog's web site.

2.  There are some common needs for anyone building their own analog
synth.  Has anyone ever investigated putting some of the stuff on a
custom chip?  With a group as big as this (almost 600 members), if
everyone tossed in $10, there would be $5000 to finance the chip.  It
need not be complex, or even include op amps.  Of course, there might be
some disagreement about what should be on it.  Specifically, I would
like to see the Moog LP ladder with its exponential transistor current
source (preferably heated) and a heated section with perhaps three or
four free current sources to use for VCO or VCLFO's.  The actual
oscillator mechanism is too personal to get a consensus on, but
everyone, I would think could use the heated transistors and ladder.
Sounds O.K. to me but who knows if the interest is really there. I've only
been here a couple of weeks myself, and mostly everyone likes to ask and
anwser questions (and bitch). For the die-hard analog synth designer, you
gotta love this list. It's like having "friends" who undersyand what the hell
you are talking about/doing. Nice to post things and get more than blank
stares...  harrybissell at netscape.net
