Using MIDI
To receive MIDI data on your keyboard,
use a MIDI cable to connect the key-
board’s
MIDI IN
terminal to the other de-
vice’s MIDI OUT terminal.
Note:
You do not need to make both
connections if you are only either send-
ing or receiving.
MIDI DATA
Your keyboard can send and receive
several different types of MIDI data. The
keyboard’s tones, rhythms, and other
types of MIDI data are sent automatical-
ly as you play.
Notes:
• The keyboard’s prerecorded tunes
cannot be sent as MIDI data.
For detailed specifications of the
MIDI function, see the “MIDI Imple-
mentation Chart” on Page 31.
Note On/Off
specifies which keys are
pressed (Note On) or released (Note
Off). Also includes how loud a note is
played as a value from 0 to 127.
Notes:
The pitch of a note depends on the
tone that is being used, as shown in
the “Note Table” on Page 29.
If the keyboard receives a “request”
to play notes outside of its range
(higher or lower), it automatically
selects the same note in the nearest
octave.
Program Change
specifies the tone.
The keyboard sends program change
data in the range of 0 to 99, correspond-
ing to tone numbers. It receives data
within the same range if GM tone map-
ping is set to N, or in the range of 0 to
127 if GM tone mapping is set to G. In
the latter case, tones in the range of 100
to 127 are translated to the closest tone
that the keyboard has.
Pitch Bend
supplies pitch bend infor-
mation. The keyboard’s pitch changes
as it receives a Pitch Bend message
through the
MIDI
IN
terminal.
Control Change
adds effects such
as vibrato and volume changes applied
during keyboard play. The message in-
cludes a control number (the effect type)
and a control value (the on/off and depth
of the effect).
Here is the data that can be received
with this keyboard and the correspond-
ing control number.
The keyboard can send Hold1 Control
Change data only when you connect a
sustain pedal and press it.
CHANGING MIDI
SETTINGS
The keyboard lets you change two MIDI
parameters, Tone Map and Keyboard

vice (Default: 01). The keyboard receives
