XR2208

[Peter Snow]

Jim, 

Thanks, that's a start.
There's nothing I need to know in particular, unless someone out there has a killer
circuit for it.
To tell the truth, I can't remember why I bought the chip in the first place - I must have
had something in mind!

I was also looking at the XR2206 and XR2207 VCO chips (the specs for those *are* up on the
EXAR web site).
I bought 6 of the XR2207 chips a few years ago with the intention of building a guitar
synth but never got any further with the idea.  I was wondering if anyone had used either
of these for synth related work - in particular as a stable VCO?

Thanks,

Peter
