Multimode filter based on the 2-pole OBx-a filter.
a High-end AS3320 based 12dB-per-Octave multi-mode filter module. With separate outputs for Low-Pass, Notch, Band-Pass and High-Pass. Based on the design of the 2-pole OBx-A filter, but with several tweaks and improvements.
CV control over Filter-Cutoff and Resonance, with a fixed V/Oct input, switchable attenuation/attenuversion on the FM-input and attenuation on the Resonance CV input.
Self-Oscillation with accurate temperature compensated V/Oct tracking over approximately 6 octaves, which allows for a very nice playable sine wave.
Input gain control with a soft-clipping circuit that kicks in at around the 12o'clock setting, with typical eurorack levels. Allowing for clean tones till unity-gain and soft-clipping and eventually hard-clipping the filter front-end at higher gain settings. When used in conjunction with a VCA before the filter, this will allow for a nice range of extra tones.
Makes use of high quality parts where applicable (Wima Polypropylene capacitors for timing, Nichicon Bi-polar audio capacitors for ac-coupling, Panasonic and Nichicon electrolytics, Texas Instruments Audio-Grade Op-amps and of course ALFA AS3320 filter chip).
Skiff friendly at 35mm deep.
Made with love in Amsterdam!
