e optional Kurzweil CC-1 continuous control pedal will work best with the PC4, but
it is also possible to use third-party continuous control pedals designed for keyboards.
Compatible pedals should use a 10 kΩ linear-taper potentiometer, with a 1/4 inch tip-ring-
sleeve (stereo) plug with the wiper connected to the tip.
RIBBON Jack

ribbon controls pitch bend, but you can also program the ribbon controller to send other
MIDI messages. To use the ribbon controller, just press it, and slide your nger along the
ribbon to change the value of the message it’s sending.
You can congure the ribbon to have one control section that runs its entire length, or to
have three sections of equal length. It sends its highest values when you press it at the end
where the cable connects. When you congure it to have three sections, each section sends its
highest values at the end closest to the cable.

option only. Don’t plug any other modular plugs into the Ribbon jack.
