The 67A Low-Pass filter is a fresh look at one of the basic building blocks of any modular synth. Two significant attributes distinguish this filter from the typical LPF found in most modulars. The first,unusual for an analogue synth filter, is the 8 pole design with ultra steep roll-off response. The second breakthrough is the capability to rotary switch select between the 8 cascaded pole stages from 6dB to 48dB in 6dB increments The ability to select the filter response makes the 67B a very versatile filter design that can emulate a wide spectrum of classic filter sounds, while also adding a few new ones to the mix. Other features include full CV controlled Resonance and on-board 3x1 mixer.
