[sdiy] Ladder filter pole

[Gene Stopp]

Hey I thought it was a great pun!

I really like Moog ladders. They have a nice "sproingey" sound when the
resonance is turned up. Yes that's a tech term :) The only one I've built
myself was a copy of the minimoog filter, all 2N3904's plus one 2N3906 for
the expo converter. It even has the discrete output opamp. Someday I'll
build it into something.

I've been eyeballing the Taurus I filter too. Seems to be even simpler, the
output amp is a single 3080 so it has a real low parts count. And we all
know how these sound...

I've not seen the Memorymoog filter!! Any .pdf's out there?

Best Regards,

- Gene

I was confused by "pole" which is a term applied to filters of course.

"Poll" is a survey....
