Control Sources
Main Control Source List
Main Control Source List
This list contains all but the last three control sources in the MIDI Control Source list. It also
contains the following control sources. All are local unless speci
fi ed as global.
32 Channel State (Chan St)
Chan St refers to whether any notes are currently active on a given MIDI channel.
Chan St switches on whenever a note is started, and switches off when a Note Off
has been received for each current note on that channel, even if notes are sustained.
33 Mono Pressure (MPress)
This is the same as the MPress control source in the MIDI Control Source list, but is
assigned by entering 33 on the alphanumeric pad when used with a parameter that
takes its values from the Main Control Source list.
34 Bipolar Mono Pressure (BMPress)
This control source generates a control signal of -1 when the value of the control to
which it’s assigned is at its minimum, and +1 when the control is at its maximum.
For example, if you had the MPress control assignment parameter assigned to send
BMPress, and you had Src1 on a program layer’s PITCH page assigned to
BMPress ,
with its depth parameter set to 1200 cents , then the layer would be transposed
down an octave when no pressure (value 0) was applied to your controller’s keys
(assuming it sends mono pressure). Maximum pressure (value 127) would
transpose the layer up an octave, while a pressure level of 64 would leave the pitch
unchanged.
35 Pitch Wheel Message (PWheel)
The K2661 is hard-wired to respond to this message. Any parameter with PWheel
assigned as its value will be affected when your MIDI controller’s Pitch Wheel is
moved.
36 Bipolar Mod Wheel (Bi-Mwl)
This control source will always respond to MIDI controller 01 (MWheel). Control
source parameters set to this value will generate control signals of -1 when the MIDI
Controller 01 message value is 0, and will generate a control signal of +1 when the
MIDI Controller 01 message is at 127, scaling all values in between. For example,
you might set Src1 on a program layer’s PITCH page to a value of
Bi-Mwl , and its
depth parameter to 1200 cents . Then as long as the MWhl control assignment
parameter is set to a value of MWheel , your controller’s Mod Wheel will be bipolar;
in this case it will bend the layer’s pitch down as you move the Mod Wheel toward
minimum, and bend the pitch up as you move the Mod Wheel toward maximum.
37 Absolute Value of Pitch Wheel (AbsPwl)
This control source always responds to movement of your MIDI controller’s Pitch
Wheel, but makes the Pitch Wheel unipolar. Whereas pulling the Pitch Wheel fully
down usually generates a control signal value of -1, this control source generates a
value of +1 when the Pitch Wheel is pulled fully down.
