WMDAperture Variable Width Bandpass Filter

WMD Aperture

WMD’s Aperture module is a crazy band-pass filter that generates everything from traditional band-pass filtering to high resonance FM style sounds. The module features dedicated controls for Frequency, Width, Low- and High-Pass Resonance, Input Volume, CV Frequency, Feedback, Dry/Wet mix, and CV Width. Additionally, each crucial parameter features CV control, so users can modulate the module’s insanity in sync with their own.
