Well, I have a Wiard Borg filter (which is a dual filter), which is
sort of based on the Buchla Low Pass Gate and the MS20 filter
(hench the name B-uchla + k-ORG). It's a FANTASTIC sounding
filter! However, it might do Doepfer good to make a vactrol filter,
since Wiard is discontinuing the series... Just a thought...
