MOTM

With a resonant highpass and resonant lowpass hooked in series, you get 2
resonant peaks at the corners, instead of 1 in the center for a single
bandpass. Also, you can control the cutoffs separately, like have an LFO
modulating the HP but an envelope modulating the LP.

Plus, if you hook the 2 filters in parallel, then you can get 12 db/oct
notch filtering, doubly resonant peaks if both are set to NF, etc. Just a
lot more flexible.
