rm, 
thanks for the clarification.  i do like the sound of those 
sallen-keys then!  somehow the idea that they're diodes got 
planted into my brain..not sure how.  
so i guess in this case i think i'd like to look into finding 
something that uses cheap sallen-keys innards (or something) 
that helps make these nice fizzy, foamy, band pass sounds.  
obviously there's more to getting that smoothness than just a 
HP/LP-in-series.
not sure, but it sounds like the sallen-key(s) in the ms20 must 
have a fairly gentle filter slope..anyone know for sure?  
the resonance of each filter comes on so nicely without being 
overbearing..
