Startup—the Details

Ribbon
Plug the optional Kurzweil Ribbon Controller into the modular Ribbon jack on the rear panel.
The ribbon controller itself should rest on a flat surface; it fits nicely between the keys and the
buttons and sliders on the front panel.
The ribbon is a continuous controller. You can program the ribbon controller to send MIDI
Controller messages 1–127, as well as several specialized messages. It generates values of 0–127
for whatever MIDI Controllers you assign it to send. Just press it, and slide your finger along the
ribbon to change the value of the message it’s sending.
You can configure 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 configure it to have three sections, each section sends its highest values
at the end closest to the cable.
Caution
: The modular jack is designed for connection to the Kurzweil Ribbon Controller option only.
Don’t plug any other modular plugs into the Ribbon jack.
Switching On the Power
The PC3A’s power switch is on the rear panel, adjacent to the power cable connection.
When you power up, the display briefly shows some startup information. The Program mode
display then appears. It looks like the diagram below, though your PC3A may be different from
the example.
The first time you power up (or after a reset), your instrument will be set to operate on MIDI
Channel 1 (as shown at the far right of the top line above).
Set the volume at a comfortable level. You’ll get the best signal-to-noise ratio if you keep the
PC3A at full volume, and adjust the level from your mixing board. You may also want to adjust
the display contrast and brightness. There are two small knobs on the rear panel of the PC3A for
this purpose.
