[sdiy] Ken's Synthacon VCF

[houshu at muj.biglobe.ne.jp]

Hello Mike,

AFAIK, the order of publication was as follows:

* Electronic Design, Ideas for Design by Mr. Steiner (197x).
* A Japanese magazine "I/O" introduced the ED article with schematic (1976).
* Mr. Tanaka cited the Japanese magazine (199x).

The schematics on the 3 articles above are identical.

Of course, the actual Steiner should have another story.
I have no information.

Best,

Sam Hoshuyama
Kawasaki, Japan.
