MIDI Functions
When this instrument and a computer are connected with a USB cable, MIDI communication can be performed. The
explanations here cover the settings necessary for performing MIDI communication between both devices.
For instructions on how to connect this instrument to the computer, refer to the “Computer-related Operations”
downloadable from the Yamaha Downloads website.
MIDI transmission channels
in Dual
Voice 1 data is transmitted on
the channel set up here.
Voice 2 data is transmitted on
the next greater channel
number relative to the specified
channel.
MIDI receive channel = ALL:
This allows simultaneous
reception of different parts on
all 16 MIDI channels. When
SMF Song data is played back
on a computer with the Voice of
this instrument, this setting is
selected. However, when a
Voice not available on the
instrument is specified, the
playback sound may not be
suitable.
MIDI receive channel = 1+2:
This allows simultaneous
reception on channels 1 and 2
only. When SMF Song data is
played back on a computer,
this setting is selected for
playing back only data of
channels 1 – 2 on this
instrument.
Panel settings (Voices, etc.) of
this instrument will not be
affected by MIDI messages
received from a computer.
Data for the Demo Songs and
Preset Songs cannot be
transmitted via MIDI.
In order to perform MIDI communication between this instrument and a computer, it is
necessary to match the corresponding MIDI transmit and receive channels. By setting the
MIDI transmit channels on this instrument, the setting of the keyboard or pedal performance
or the program change can be transmitted over the channel number corresponding to a
specified channel on the computer. By properly setting the MIDI receive channels on this
instrument, only data of the specified channel will be played back in the MIDI data received
from the computer.
Setting the MIDI Transmit Channel
While holding down [DEMO/SONG] and [PIANO/VOICE], press the D4 – F4keys.
Default setting: Ch 1
Setting range: Ch 1 – 16, off
Setting the MIDI Receive Channel
While holding down [DEMO/SONG] and [PIANO/VOICE], press the G4 – B4 keys.
Default setting: ALL
Setting range: Ch 1 – 16, 1+2, ALL
“Local Control” refers to the fact that, normally, the keyboard of the instrument controls its internal tone generator,
allowing the internal voices to be played directly from the keyboard. This situation is “Local Control On,” since the internal
tone generator is controlled locally by its own keyboard. Local Control can be turned off as desired, so that the keyboard
of the instrument does not play the internal voices.
Default setting: ON
While holding down [DEMO/SONG] and [PIANO/VOICE], press the B3 key. Pressing the
B3 key repeatedly toggles between Local Control On and Off.

Voice List
The information related to Voice changes is called “program change” in MIDI. Sending and receiving program change
messages can be enabled or disabled as desired on this instrument. For example, if the relevant transmit and receive
parameters are set to ON, Voice change information in this instrument can be transmitted to or received from a computer.
(However, the Voice as played from the keyboard is maintained and does not change.)
For information on program
change numbers for each of
the Voices of the instrument,
see the “Voice List” below.
Default setting: ON
While holding down [DEMO/SONG] and [PIANO/VOICE], press the C4 key. Pressing the
C4 key repeatedly toggles between Local Control On and Off.
Information related to non-note expressive changes, such as the use of a sustain pedal, is called “control change” in
MIDI. Sending and receiving control change messages can be enabled or disabled as desired on this instrument. For
example, if the relevant transmit and receive parameters are set to ON, pedal performance information on this instrument
can be transmitted to or received from a computer. (However, the performance of pedals and other controls as played
from the instrument is maintained and does not change.)
For information on control
changes that can be used with
the instrument, see “MIDI
Implementation Chart” page 4.
Default setting: ON
While holding down [DEMO/SONG] and [PIANO/VOICE], press the C#4 key. Pressing
the C#4 key repeatedly toggles between Local Control On and Off.

pitch may not be changed according to the pitch bend setting
range.
*2 These Control Change messages cannot be transmitted by panel
operations, but can be transmitted by Song playback data.
