About MIDI
● All Notes Off (Control #123)
Clears all notes currently on for the specified channel.
However, if Sustain Switch or Sostenuto Switch is on,
notes will continue sounding until these are turned off.
This message cannot be sent by any CBX-K2 operation;
however, when a MIDI error occurs, this message is sent
automatically.
● Mono (Control #126)
Performs the same function as when an All Sounds Off
message is received, and if the 3rd byte (mono number)
is in the range of 0 - 16, sets the corresponding channel
to Mono Mode (Mode 4 : m = 1).
● Poly (Control #127)
Performs the same function as when an All Sounds Off
message is received, and sets the corresponding channel
to Poly Mode (Mode 3).
■ Program Change
Messages which select voices.
■ Channel Aftertouch
The CBX-K2 keyboard does not have aftertouch sensi-
tivity and thus cannot send aftertouch messages by
keyboard pressure. However, Channel Aftertouch data
can be sent by the Assignable Wheel or Slider. Channel
Aftertouch affects the sound of all notes when it is
applied.
■ Polyphonic Aftertouch
The CBX-K2 keyboard does not have aftertouch sensi-
tivity and thus cannot send aftertouch messages by
keyboard pressure. However, Polyphonic Aftertouch
data can be sent by the Assignable Wheel or Slider.
Polyphonic Aftertouch affects the sound of only the top
note (when several notes are played together) when it is
applied.
■ Pitch Bend
Pitch Bend messages are continuous controller messages
that allow the pitch of designated notes to be raised or
lowered by a specified amount over a specified duration.
SYSTEM MESSAGES
System messages are the data related to the overall system
of the device.
■ System Exclusive Messages
System Exclusive messages let you use the CBX-K2 to
control various functions on connected devices, including
master volume and master tuning, effect type and various
other parameters.
● Master Volume
This message controls the volume over all MIDI chan-
nels.
F0 7F 7F 04 01 ll mm F7 (Hexadecimal)
* mm(MSB) = appropriate volume value, ll(LSB) =
ignored
■ Active Sensing
Once FE (Active Sensing) has been received, if no MIDI
data is subsequently received for longer than an interval of
approximately 300msec, the CBX-K2 will register an
Active Sensing error.
Refer to the following MIDI Data Format for more infor-
mation about the various messages.
