■ MIDI Transmission
● Transmit Condition
*1 This applies only to the highest note played.
*2 This is output only when a MIDI buffer full error
occurs.
<SW1> When the CBX-K1XG is set to send <<F8>>
messages, <<F8>> messages from the CBX-K1XG will
be output. When the CBX-K1XG is not set to send
<<F8>> messages, <<F8>> messages from the CBX-
K1XG will not be output, but <<F8>> messages from a
connected external device will be merged.
<SW2> When Merge is set to ON, the incoming data is
merged.
<Filter> This is Merge On/Off for each channel.
1. CHANNEL VOICE MESSAGES
1.1 Note On / Note Off
1001nnnn 9n Status n=Channel number
0kkkkkkk kk* Note # k=0(C-2)...127(G8):C3=60
0vvvvvvv vv Velocity v=0:Note off,
v=1...127:Note on
* “kk” is the hexadecimal expression of 0kkkkkkk; same as
for “tt”, “aa”, etc.
Messages which are generated when the keyboard is played.
Reception note range = C-2 (0) – G8 (127), C3 = 60
Velocity range = 1 – 127 (Only the Key On velocity is received)
Key On: Generated when a key is pressed.
Key Off: Generated when a key is released.
Each message includes a specific note number which corresponds to
the key which is pressed, plus a velocity value based on how hard the
key is struck.

0kkkkkkk kk Note # k=0(C-2)...127(G8):C3=60
0vvvvvvv vv Value v=0...127
Messages which let you control various functions by the pressure you
apply to the keys after the initial striking of the keys.
When pressing several keys simultaneously, after touch of only the
highest note number is output.
Though the keyboard of the CBX-K1XG itself has no after touch, af-
ter touch data can be transmitted from the ASSIGNABLE Wheel when
Channel pressure or Polyphonic key pressure is assigned to the Wheel.

0ccccccc cc Control #
0vvvvvvv vv ControlValue v=0...127
Messages which control volume, panning, and other controller param-
