Using Global Controllers in MONO Mode
Global controllers are controllers sent on one channel that affect all other channels
simultaneously. They can be useful in reducing the number of MIDI events required to achieve
particular effects, and can thereby reduce the delays sometimes associated with overloading
MIDI. Some guitar controllers can transmit global controllers, and the KT can respond to them.
In MONO mode (A or B) the
base channel minus one
becomes the MIDI channel for global
controllers (pitch bend, pressure, etc.). For example, if the base channel is channel 3, any
controllers received on channel 2 will be interpreted as global controllers and will affect all
sounds being played. If the base channel is channel 1, channel 16 becomes the channel for global
controllers. Each track will also respond independently to controllers sent on its own channel.
For example, each guitar string on a MIDI guitar can send independent pitch bend, while the
“whammy bar” controller could be sent on the global channel to affect all sounds.
XCtrl Range: 000 to 127
Use XCtrl to assign external MIDI controllers to affect the KT.
Most controllers on a synthesizer — mod wheel or breath controller, for example — have a MIDI
controller number that can be assigned to this parameter. Doing so will make a particular
external controller available as a modulator to any of your sounds.
One modulation source that can be selected in Edit Sound mode is XCTRL. The value of the
“XCtrl” parameter is a MIDI controller number. When the KT receives MIDI Controller messages
corresponding to this controller number, they will be routed to all parameters that have been
programmed with XCTRL as a modulation source. Suppose, for example, you are playing the KT
from a keyboard with a breath controller (or want to use a breath controller as a modulator when
playing the KT keyboard). You can set up a sound on the KT in which the filter cutoff frequency
is modulated by XCTRL. If you then set “XCtrl=02,” the breath controller can modulate the filter,
or any other voice or effect parameter that has its modulation source set to XCTRL, in the sound
you have created.
The following controller numbers are commonly supported:
Number Controller Number Controller
1 Modulation Wheel 64 Sustain
2 Breath Controller 66 Sostenuto
4 Foot Pedal 70 Sound Variation (Patch Selects)
6 Data Entry MSB 71 Harmonic Content (Timbre)
7 Volume 72 Release Time
10 Pan 73 Attack Time
12 Effect Modulation 74 Brightness
