WMD - Aperture

the aperture is a variable-width bandpass filter with fast and tactile controls. it is capable of simple filtering, self oscillation fm timbres, nasty acidic squelches, and capturing images of ufos descending from the heavens on a cold winter's night. the concept is a bandpass that ranges from transparent to gnarly, with precision controls that behave under stress, all while being joyful to wreak havoc with.features include:variable bandwidth via tactile and cv controlseight pole filter coreindependent resonance and self oscillation of both sides of the filter with cvfeedback circuit with two modes and cvinput level vcaadditional cv for opening the band either side of centerv/oct trackingtemperature compensateddry / wet mix for parallel filtering sounds*leds along the top indicate width and position of the filterknobs:frequency: controls the center frequency of the bandwidth: controls the width of the band.freq cv: attenuverter for the cv input for precise control over the frequency o
