So I just recently got a Moog FreqBox and am looking forward to pairing it with my EP-1 tonight... but thinking ahead... What are some other filters out there that are possibly a little better equipped to get you the sort of filter sound on Moog synths? I know the Moog LPF has an envelope follower, but no attack/decay controls. And of course, there's the Pigtronix Attack Sustain and other such pedals, but I'm looking for that kind of control over the filter, not the overall signal. I know the Meatball and its clones have attack and decay controls, but is that it or are there others? Brian P.S. The sort of filter sound/control I'm talking about can be found here, from about 1:00 to 2:30.
