Behringer can be controversial.
-- 33PO

While true, in the case of the ARP 2500 clone modules, they are Rob Keeble (AM Synths) designs. And in this case, B wasn't stepping on anyone's toes (there's a first time for everything, I suppose).

I have the 1006 (and a couple other B2500 modules), and while it works great within the 2500 setup, it is a royal pain to use outside of that context (you must use the filter in order to use the amp), so I would second @33PO on a different filter. If you want the ARP filter sound, G-Storm Electro has the TONUS-VCF, which is the classic ARP 2600 4012-filter clone (I personally like it better than the 1006, although the 2-pole 1047 Multimode Resonator is loads of fun!).
