The VCFB, or, Voltage Controlled Filterbank is a very interesting and unique module. From an early catalogue: "Upon special request, three or more filters can be linked to achieve the function of multiple band-pass spectrum filters (equivalent to voltage-control paramteric equalization). Filter banks of thiy type are expectionally versatile because the multiple band-pass functions can be dynamically adjusted around any portions of the audio spectra. A typical filter bank with four filters in series provides three fully adjustable BAND-PASS outputs, plus LOW and HIGH-PASS outputs."
Essentially, the VCFB is 3 classic '73 filters in series, configured to create a beast. It also has all the well know '73 filter mods, like the "trigger" input.
