The SEM module was originally made to compliment other synthesizers but later came into its own as a great sounding synth. The unique filter that allowed continuously variable operation from low pass to high pass gave it a sound that no other had. When multiple SEM's were connected into a 4 or 8 voice polyphonic system, it became a thing of beauty.
