Verbos Bark Filter Processor

Verbos Bark Filter Processor

Here are four of the movies I created on using the Verbos Electronics Bark Filter Processor. In the first movie, I play with using it as an extreme graphic equalizer or multiband formant filter while giving an overview of its large number of inputs, outputs, and controls. The last minute and a half explains what the Bark Scale is, which is what sets this module apart from other graphic-style equalizers that that often use an octave-based system for their frequency bands.

This second movie shows how to use the Frequency Scan and Spectral Tilt sections to control which frequency bands are opened up. I first both the front panel knobs, and then voltage control these sections using a knob, slider, and XY touch pad from a controller keyboard. As several Verbos modules also feature Scan and Tilt sections, this also acts as a primer for controlling those modules:

This third movie focuses on using it as a vocoder. One input can be routed to 6 of its 12 bands, generating voltages that follow the strength of the first input signal in each of those bands. A second input can then be routed to the other six bands, controlled by the voltages generated by the first set of bands and therefore imposing the harmonic signature of the first sound onto the second. I demonstrate using this trick to have percussion loops (its strength), voice, and sound effects or ambiences filter your synth’s sound.

This fourth movie on the Verbos Electronics Bark Filter Processor focuses on using the independent envelope followers attached to each of its 12 bands to trigger other sounds (in this case, a Noise Engineering Basimilus Iteritas and an Erica Synths Pico Drums). I talk a bit about choosing different frequency bands to isolate different sounds, and demonstrate using a trigger delay (from a Roland 572) to clean up spurious triggers.
