Check out this circuit:

It will easily tune an octave with just a few volts of tuning voltage.

I am extremely interested in this article. I signed up with EDN over 12
hours ago, but the only thing I've gotten is that my "subscription is
processing", whatever that means. So far it means that I don't have the
required password to access the archive. :-(

Since the subscription is free, and I've already tried completing it,
can someone please e-mail me this file?
