arp oddysey filters again! :)

[cyborg0 at GlobalEyes.net]

I was looking in the archives, and i found that it "seems" that the
following info about oddys is true
1> white face arps have a 12db SEM type state variable filter
2>*some* black faced arps have the moog ladder filter
3> later oddys have the lm3394 quad op-amp based 24db filter (which, to
me, doesnt sound all that good, I like the other 2 better, but this is
what is on my oddys)

Now, a while ago, a person posted plans for a new filter that had a 12db
/24db switchable filter.. Where has this person gone? 
At one time, I had the plans, but have been unable to find them since.
They were in .ARJ and postscript format. I now have all the components,
but am unable to make the PCB now!!
someone help me out.. I looked in the archives, and have been unable to
find the post.
thanks.
