TRANSPOSE Buttons
The TRANSPOSE buttons can be used to change the tuning of notes played on the PC4
keyboard in semitones (also known as half steps). The current transpose amount is shown
in the top line of the display. Press both TRANSPOSE buttons simultaneously to reset the
transposition to 0.
Pitch Wheel and Modulation Wheel
Use each wheel to respectively perform pitch bends or vary the modulation amount. The
Modulation Wheel will control modulation for each Program or Multi. The name of the
current modulation assignment is shown in the display when the wheel is moved.
VARIATION Button
Pressing the VARIATION button will perform an assigned variation for each Program
or Multi. The name of the current assignment is shown in the display when the button is
pressed.
The VARIATION button has two states, off (not lit) and on (lit). The VARIATION button
will typically modify the sound by adding an orchestral string section or synth pad layer, or
enabling an effect.
For KB3 Organ Programs, the VARIATION button controls the Rotary Speaker speed,
changing between fast and slow. The display shows “KB3” when a KB3 Program is selected.
CONTROL Section
The CONTROL section is used to control various Program and Multi parameters.
In Program Mode:
The knobs, sliders, and buttons control synthesis and FX parameters
for the current Program. Controller assignments can be adjusted or set to user-assignable
parameters in Program Edit Mode.
In Multi Mode:
The knobs, sliders, and buttons typically control Zone volume, synthesis
and FX parameters for the current Multi. Controller assignments can be adjusted or set to
user-assignable parameters in Multi Edit Mode.
In Program and Multi Mode:
When a KB3 Organ Program is selected, some of the knobs,
sliders, and buttons may perform Organ functions labeled on the front panel. The display
shows “KB3” when a KB3 Program is selected.
ARPEGGIATOR Section
Use the ARP and LATCH buttons to control the PC4’s Arpeggiator.
