PC3K Programs
Info Box
There's a box at the left side of the display. The info box, as it's called, displays information about
the current program (there's also an info box for Setup mode).
Soft buttons
On most PC3K screens, the bottom line of the display identifies the function of each of the
buttons beneath the display. We call these buttons soft buttons, because they do different things
depending on what's currently showing in the display.
In Program and Quick Access modes, you can change octaves with the Octav‐ and Octav+
buttons under the display. The Info soft button shows you relevant details about the current
item. The Xpose‐/Xpose+ buttons are a shortcut for quick transposition in semitone (half step)
increments. You can use them to transpose the entire PC3K as much as three octaves up or
down. The top line of the display shows the current amount of transposition (Xpose). Press both
Xpose buttons simultaneously to return transposition to zero.
The Panic button (or a double press of Cancel and Enter at the bottom of the alphanumeric
keypad) sends an All Notes Off message and an All Controllers Off message—both to the PC3K
and over all 16 MIDI channels. You won't need it often, but it's nice to have.
VAST Programs
A "normal" VAST program is what most of the factory programs are. The info box contains
details about the different layers in each program, usually indicating the keymap used in each
layer. The line under the keymap name indicates the layer's keyboard range. In this case, only
the first two displayed layers extend across the entire keyboard (A 0 to C 8). The × symbol to the
right of each layer shows that the keymap is a stereo keymap.
KB3 Programs
KB3 (organ) programs differ from VAST programs in that they don't have layers. Instead they
rely on oscillators that mimic the tone wheels used in many popular organs. Consequently, the
info box shows only the waveform used in the program. Because of their architecture, KB3
programs require different processing within the PC3K. KB3 programs play only on a single
channel at a time (VAST programs will work fine on that channel, too).
The quickest way to get to the KB3 programs is by pressing the KB3 button that's above the
sliders.
