Morpheus has 14 order filters. The Proteus/command station synths have a 2, 6 and 12 order filters. Some of them are really crazy and unusual, and fantastic for basses or choirs (DJAlkaline, Roguehertz, Meatygizmo, BassOMatic, Ubulator, etc... ) , and they are similar to effects. 12 order filters reduce polyphony to 64.
The Q parameter can behaves as the resonance, ring tone, mid frequency, depth of notches and band selector depending of the filter you choose. But Q is NOT a realtime parameter on the proteus series. You hold a note, and modulate Q, nothing happens, notes must be retriggered to hear the Q modulations. Maybe that´s the difference.
