Anybody know of a filter unit that has VCA (amp) ADSR, not just filter ADSR, but doesn't cost a small fortune? I'm looking for something self-contained, not a module that goes into a Eurorack or something. I'm not sophisticated enough for that! I think the Sherman Filterbanks, the MAM Warp 9, and the Waldorf 4-Pole all have amp ADSR, but they're either expensive, hard to find, or both. Any alternatives?
