Walking Stick Dual-CV Ribbon Controller Demo

YouTube via 12T0NE

"This is just a little improv thing I did whilst goofing around with a few Dotcom modules and one of my Dual-CV Ribbon Controllers . These controllers add a new dimension to my standard 20" single-CV ribbon design, by offering a secondary CV output that can be varied by applying different amounts of pressure to the ribbon's surface.

For the purposes of this demo, I placed enough modules inside of a small 8-space cabinet to build up a very basic FM patch. The ribbon's CV is being routed through a set of multiples to control the pitch of the two VCOs, and the controller's pressure CV is similarly routed through multiples to the state-variable filter's cutoff frequency, and to the control input of a single VCA. Oscillator #2 is running thru this VCA, back into the frequency input of oscillator #1. When pressure is applied to the ribbon's surface, the VCA opens up and increases the amount of frequency modulation going on between the oscillators. In absence of a final VCA, I'm using the ribbon's pressure sensitivity to open-and-close the cutoff frequency of the filter. With no pressure applied, the filter allows no sound to pass. This allowed me to "envelope" the notes being played on the controller with a single touch of the finger.

Thanks for viewing!"
