Transmitted Data - Yamaha CBX-K2 Owner's Manual

2. Overview
Transmitted data includes messages from the CBX-K2 itself
and messages from an external device connected to MIDI
IN. Besides conventional MIDI messages, single byte data
can also be transmitted.

3. Transmitted Data

3.1 Channel Voice Messages
(1) Note on/off
n=Channel
kk=Note number
vv=Velocity
(2) Polyphonic key pressure
n=Channel
kk=Note number
vv=Pressure value
* When pressing several keys simultaneously, after touch of only
the highest note number is output.
* Though the keyboard of the CBX-K2 itself has no after touch,
after touch data can be transmitted from the Assignable Wheel
or Slider when Channel pressure or Polyphonic key pressure is
assigned to the controller.
(3) Control change
n=Channel
cc=Control number
vv=Control value
* When RPN or NRPN is assigned to the Assignable Wheel or
Slider, the MSB, LSB and data entry values are transmitted in
a group each time.
(4) Program change
n=Channel
pp=Program number
(5) Channel pressure
n=Channel
vv=Pressure value
* Though the keyboard of the CBX-K2 itself has no after touch,
after touch data can be transmitted from the Assignable Wheel
or Slider when Channel pressure is assigned to the controller.
(6) Pitch bend change
n=Channel
ll=Pitch bend value
mm=Pitch bend value
* MSB and LSB data (depending on Pitch Bend Wheel position):
MSB
Maximum 0
Center 64
Minimum 127
* When MSB < 64, LSB = 0. When MSB > 64, LSB = (MSB -
64) x 2.

3.6 Single-byte Data Transmission
(1) Single-byte data
Separate from conventional MIDI message transmission, single
byte messages can also be transmitted.
3.7 Others
* Running Status bytes are not used. However, incoming
Running Status messages are added and transmitted.
* If the incoming Note Off messages include <<8n>> status, the
<<8n>> status is merged and output as is. (The CBX-K2
transmits Note Off messages as <<9n>> status with a velocity
of 0.)
