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

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
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-
.
TONE
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
button to turn on
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
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
Using MIDI
n is the channel num-
