The 67B Low-Pass filter is a new look at one of the basic building blocks of any modular synth. Two features distinguish this filter from the typical low-pass found in most modulars. The first is the ability to dial in the filters order response between first order and 8th order or 1 to 8 poles, each pole providing -6dB of attenuation of frequencies above the filter cutoff resulting in a filter with -6 to -48dB of attenuation. The second feature is the -48dB 8th order response which is unusual in a synth filter due to the usual complexity of the circuit.
The variable pole feature makes the 67B a highly versatile filter having the ability to select between the nasal character of a 2 pole -12dB and the thundering bass of a -48dB 8 pole and all responses in between. Other features include full CV controlled Resonance and on-board 3x1 mixer.
