|Four very simple filters with manually adjustable center frequency and resonance. Generally they're set and forget, letting the incoming audio do all the work! No precision or voltage control here, but they sound great, and they're good for example for setting-up artificial resonant cavities when modeling virtual instruments.
While a different actual circuit, this module is presented in the spirit of the early Buchla systems, which obtained part of their unique sound by employing lots of simple bandpass filters such as these.
This Quad Band Pass arrangement is presented in the same format as our popular Quad Low Pass Gates so that they may work either independently or together in your quest for that signature sound.
