[sdiy] eml 101 VCO: continuously from tri to sqr to saw

[ganesha]

Hi all,

Probably a complete newbie question but I like the way
you can change the waveform continuously from tri to
square to saw on the eml 101 vco's. I would like to
use that on a vco module I'm building myself, but I
have a question about the schematic:

What kind of potmeter is used because it seems to have
a connection in the middle where you can connect the
square waveform?

regards, Kris
