Transmitted Data - Yamaha CBX-K1 Owner's Manual

2. Overview
Transmitted data includes messages from the CBX-K1 itself
and messages from an external device connected to MIDI
IN. Besides conventional MIDI messages, single byte
messages 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-K1 itself has no after touch, after
touch data can be transmitted from the ASSIGNABLE Wheel when
Channel pressure or Polyphonic key pressure is assigned to the
Wheel.
(3) Program change
n=Channel
pp=Program number
(4) Control change
n=Channel
cc=Control number
vv=Control value
* When RPN or NRPN is assigned to the ASSIGNABLE Wheel, the
MSB, LSB and data entry values are transmitted in a group each
time.
(5) Channel pressure
n=Channel
vv=Pressure value
* Though the keyboard of the CBX-K1 itself has no after touch, after
touch data can be transmitted from the ASSIGNABLE Wheel when
Channel pressure or Polyphonic key pressure is assigned to the
Wheel.
(6) Pitch bend change
n=Channel
ll=Pitch bend value
mm=Pitch bend value
3.2 Channel Mode Messages

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-K1 transmits
Note Off messages as <<9n>> status with a velocity of 0.)
