vactrol filter success!! (Buchla 292 and 4-pole)

[mark verbos]

Last night I had success building......

a Buchla 292c lopass gate. I used CMOS analog switches insted of LF13331 wierdo
FET chips. I gave the chips +/- 7.5 volts and it works great. Really nice
sounding module.

A 4 pole vactrol filter. I just ran vactrol to vactrol and capacitors to ground.
no buffering. i had a little problem with the resonance, but I made it invert
and now it is sweet. This one sounds really smooth.

these are both dead simple and only use a small board and a handful of parts.

all the info is @ www.simple-answer.com/DIY.html


the bad news was the ad/ar envelope that NOBODY IS HELPING ME WITH;)
