We came across this great video by PUSCHA, in which he demonstrates his techniques for using fixed filter banks — in this instance, the Verbos Bark Filter Processor.

There are some really inspiring patch ideas and lovely sounds! We especially loved the pinged sound at around the 12:30 mark, what a beautiful tone!

Have a listen for yourself!

The Bark filter is a twelve band fixed filter bank with individual outputs and envelope followers on each band, as well as a voltage controlled mixer for blending the outputs.

The filters are steep, 6th order band pass filters with yellow LEDs indicating the level at the envelope followers’ outputs. The voltage controlled mixer has sliders and individual CV ins and draws the, “center”, “width” and “tilt” controls from the Harmonic Oscillator allowing the fixed filters to be scanned across blended and mixed in various ways, all at the same time. The even and odd filters can be patched in and out separately, and one side’s followers can control the other side’s levels like a vocoder.

For more information about the Bark Filter see the Verbos website.
