No, they aren't just EQs. The effect is more dramatic, because
a) you can completely attenuate certain bands with ∗steep∗
filter slopes, and
b) certain filter banks will add a nice coloration to the sound
even with all potentiometers at maximum.
I've built a modern version of the Moog 907 filter bank some
weeks ago - one more step to get the "trademark Moog Modular"
sound. I'll make some demos when I find the time.
