Using MIDI
change the tone, layer, split, and so forth
without affecting the MIDI input.
External Mode
The mixer’s setting affects the MIDI input da-
ta. This is convenient when you want to con-
trol MIDI input channel on/off setting. For
example, you can turn off channel 3 of the
MIDI input data and play on the keyboard for
that part. Also, you can change the tone, vol-
ume, and so forth on the received MIDI data.
Refer to “Using the Mixer” on Page 20 for
more information about using the mixer func-
tion.
Notes:
• The keyboard turns the channel on or off
immediately after you select this option.
Other changes become effective from
the next MIDI input data.
• You cannot change the mixer settings
on the keyboard because the mixer is in
external mode, but you can change the
tone of the current channel using
TONE
.
External Solo Mode
You can use this mode to check the contents
of a specific channel of the received MIDI da-
ta. The on/off setting of the channels is differ-
ent from the external mode. Press the
corresponding
CHANNEL
button to turn on
only that channel and turn off all other chan-
nels.
External Play Mode
This is the opposite of the external solo
mode. Press a channel button to turn off that
channel while keeping all other channels on.
You can turn off one part of the received
MIDI data so you can play along.
Tip: The difference between internal mode
and external play mode is that external play
mode allows you to turn off a part of the MIDI
received data.
NOTES ABOUT THE MIDI
IMPLEMENTATION CHART
The “MIDI Implementation Chart” on Page 54
illustrates the details of the keyboard’s MIDI
function. An O in the chart means that the
keyboard has this feature; X means it does
not have this feature. This section explains
what the keyboard can do.
Basic Channel — MIDI uses up to 16 chan-
nels to exchange data. As in a TV broadcast,
different channels send different data.
Mode — The chart shows that Mode 3 is
OMNI OFF, POLY. This means the keyboard
sends and receives polyphonic data on only
one channel at a time.
Note Number — This number represents
each key of the keyboard. The lowest num-
ber (0) is five octaves below middle C. Since
the keyboard’s lowest note is two octaves
below middle C and the highest is three oc-
taves above middle C, your keyboard can
send a note number between 28 and 103.
But, it can receive 0 through 127 note num-
bers, so those keys outside the keyboard’s
key range are interpreted as notes inside the
key range.
Velocity — This number shows how fast the
key was pressed, or how loud the note
should sound. 1 is the lowest velocity, pianis-
simo; 127 is the loudest, fortissimo. 0 means
the key is released.
9n — This means that the Note On message
is 9 hexadecimal, and
n
is the channel num-
ber.
For example, if you select Channel 16 and
press Key D in mezzo-piano, 9E (E is 15 in
hexadecimal; note that Channel 1 is 0 in
MIDI data) is first sent from MIDI OUT, then
