[sdiy] Electrix Filter Factory

[Clint Davis]

Has anybody modded a Filter Factory?

I really like the thing, but the problem is that the filter goes into
oscillation really easily.  Thing Is I think that the filter was primarily
intended to be used in it's two pole stereo mode, rather than in the 4 pole
mono.  I was thinking of putting a resistor in series with the resonance
knob and placing a spdt switch in there to bypass it.

I suppose if I'm going to undertake any modification of the thing, I might
as well put an LFO out for it.

Anybody know of any places you could find a schematic for the thing?

I also wonder if it would be possible to provide seperate ins and outs for
each stage.  I would think that would also be pretty easy since there's
already two ins and outs via the stereo plugs...  plus it would be nice to
make a small panel with all the ins and outs so I could just install the
bugger in a rack and never have to sweat the fact that the module's cv ins
are in the rear.
