MOTM

The SEM filter is state variable 2 pole, so is not as dark as a 4 
pole filter. The only other 2 pole available right now from MOTM is 
the 420 (the upcoming 480 will be also).

The SEM has a continuously variable control to morph from LP to BP to 
HP, not sure if you can get to notch too. It can sound nasally if you 
use BP or HP, naturally. Otherwise I'd call it "warmly aggressive" 
<g>. Listen to the Weather Report classic "Birdland" (not the synth 
bass intro which is 2600, but the polyphonic synth brass lines which 
are Obie 4-Voice).
