KB3 Effects And Real-time Controls

You have real‐time control over many components of KB3 programs directly from the front
panel. The knobs emulate the drawbars that are so essential to the tone wheel sound, while the
assignable switches above them can control the KB3 effects: Leslie, vibrato, chorus, and
percussion. Use the Shift button next to each set of controls in order to access all of the available
parameters.
When using a KB3 program in Program mode, the assignable knobs and switches always
control KB3 effects. In Setup mode the assignable switches mute and unmute zones by default.
If you want the assignable switches to control the functions of a KB3 program in a setup, you can
edit the setup and automatically assign the KB3 controls using the KB3CTL soft button in the
Setup Editor. See Set Controls KB3 (KB3CTL) on page 7‐66.
Drawbars In KB3 Mode
One of the standard performance features of many tone wheel organs is the set of drawbars for
emulating the stops on a pipe organ. Moving the drawbars controls the amplitude of either the
fundamentals or the harmonics of the notes (out to increase amplitude, in to decrease it.)
The PC3LE's knobs serve as the nine drawbars found on most tone wheel organs. Turning the
knobs down is the equivalent of pushing the drawbars in (removing fundamentals or
harmonics.) The table below shows how the PC3LE's knobs relate to standard drawbar
functions.

KB3 Mode Effects Buttons (Assignable Switches)
When using a KB3 program, the PC3LE's assignable switches control KB3 effects. The LEDs of
the assignable switches indicate the status of the various effects for the current KB3 program.
This status is saved as part of each KB3 program. You can change the effects in real time by
pressing the buttons (or by sending the appropriate MIDI Controller values from an external
MIDI controller, see Table 6‐3 on page 6‐8 for details.)
On/off settings of the assignable switches for a KB3 program are not automatically saved; the
switches return to their programmed on or off state the next time you select the program. If
you've made changes to their state that differ from those saved with the program, the Save
button will light. Press the Save button to save changes to the current program, or to rename the
program and save it under a new ID#. When choosing an ID#, press the ‐ and + buttons
simultaneously (below the Alpha Wheel) to jump to the original ID# if you would like to replace
the original program. If you change the state of the assignable switches while in the Program
Editor, the PC3LE will prompt you to save the changes when exiting the Program Editor. If you
don't like the changes, you can exit without saving, and the program will revert to its previous
settings.
In KB3 mode the assignable switches also respond to and send MIDI Controller messages. See
Table 6‐3 on page 6‐8 for details.
