Dual SeM20 filter
The SeM20² is a classic 2 pole state variable Eurorack filter based on the Oberheim SEM's filter with the resonance section of the MS20 grafted on for extra bite and the input section modified to overdrive the single, much like the OSCar. The Dual SeM20² manages to put 2 in a 16HP module without sacrificing any of the features or the sound of the original.
