Controllers
and PitchDwn (controller destinations 130 and 131) as a Pitch Wheel destinations (see PWUp
and PWDn on The WHEEL Page on page 7 ‐ 33,) and use MIDI 21 and MIDI 15 (controller
destinations 21 and 15) for other controllers, such as the Sliders and Ribbon (see Aux Bend 1 Up/
Down and Aux Bend 2 Range below.)
Keep in mind that not all MIDI devices respond to Bend Range messages. With many older
MIDI instruments, you must set bend ranges on the devices themselves.
Changing programs sends a Bend Range message with the current program’s values. So does
pressing Panic , which is a quick way to reset your PC3K or MIDI slaves if you’ve used a
controller to modulate the bend range.
Aux Bend 1 Up and Aux Bend 1 Down
Like BendRangeUp/Down, Aux Bend 1 defines the range for Pitch Bend messages, but does so
for those physical controllers assigned to controller destination 21, MIDI 21 . There are two
parameters related to AuxBend 1: an upward value (AuxBend1Up) and a downward value
(AuxBend1Dwn). This means that you can set different values for upward and downward pitch ‐
shifting. For example, you could get the Pitch Wheel to give you both vibrato and whammy ‐ bar
effects for the guitar program in a setup. In the zone that contains the guitar program, set
AuxBend1Up to 2ST and AuxBend1Dwn to 12ST , then assign the PWUp and PWDn parameters
on the WHEEL page to a value of MIDI21 . Now moving the Pitch Wheel up gives you a whole
tone of upward bend, while moving it down gives you a full octave of downward bend.
In most factory setups, AuxBend 1 is set as the destination for the optional Ribbon controller
(see The RIBBON Page on page 7 ‐ 40).
Aux Bend 2 Range
The PC3K allows you to specify a third pitch bend range; this is called AuxBend 2, and it defines
the range for controllers set to controller destination 15, MIDI 15 . For AuxBend 2, you can set
only one range for both upward and downward pitch bending.
A Note About Continuous Controllers and The BEND Page:
Unlike the Pitch Wheel and Ribbon controller, other continuous controllers, such as a slider, will
not automatically return to the original center pitch. This can make it hard to accurately return
the controller to it’s center position by hand. In these cases, it is useful to use a separate
controller for bending only up or down. For example, to have a slider only bend up, use a slider
with an Add value of 64 and a Scale value of 50%, and Curv set to Linear. The bottom of the
slider will now be the center pitch, and the top of the slider will be the top of your bend range.
To have a slider only bend down, use a slider with an Add value of ‐ 127 and a Scale value of
150%, and Curv set to Linear. The top of the slider will now be the center pitch, and the bottom
of the slider will be the bottom of your bend range. See page 7 ‐ 30 for more on setting continuous
controller parameters.
Controllers
Controller editing is one of the strongest aspects of the PC3K’s usefulness as the main controller
for a sophisticated MIDI studio. In this section, we’ll talk about two different types of
“controllers” as they apply to the PC3K. One is the physical controllers: the wheels, buttons,
pedals, etc. that you move with your fingers or feet. The other is MIDI Controllers, which are
MIDI commands sent by the PC3K. For our purposes, “MIDI Controllers” includes the complete
set of Controllers defined by the MIDI Specification, as well as pitchbend, aftertouch, and a few
other useful MIDI commands. To fend off confusion, we’ll refer to the PC3K’s physical
controllers with a lower ‐ case c, and MIDI Controllers with an upper ‐ case C.
