■ MIDI Default Values
When the power is turned on, the instrument defaults
to the following MIDI settings.
MIDI transmission channel 1
MIDI receiving channel 1
LOCAL ON
PROGRAM CHANGE ON
CONTROL CHANGE ON
■ Changing the MIDI Transmit Channel
The MIDI standard provides 16 separate channels for
the transmission of performance data. MIDI master
keyboards (controllers) can therefore control up to 16
individual slaves (or groups of slaves acting in uni­
son) by sending channel messages. Performance data
messages
always include a channel number. Each
device on the network reads all messages, but only
responds
to messages that match the connected
instrument's MIDI receive channel.
Selecting o MIDI channel
To change the MIDI transmit channel, hold
down the [TRANSPOSE/FUNCTION] switch
and press the appropriate key between C2 and
D#3.
14 16
8 10 12 13 15
Note: When the power is turned on, the instrument is set
up to transmit on channel 1.
■ Changing the LOCAL ON/OFF Setting
The LOCAL ON/OFF setting allows you to use the
instrument as a "silent"' MIDI controller. When LO­
CAL is set to OFF, the instrument's internal voices
will not sound-only the sounds of the connected MIDI
devices will be heard.
Note: When the power is turned on, the instrument de­
faults to LOCAL Mode ON.
Switching lOCAl on or off
To change the setting, hold down the [TRANS­
POSE/FUNCTION] switch and press the [PI­
ANO] switch.

■ Sending PROGRAM CHANGE Requests
A PROGRAM CHANGE request is a channel message
that asks devices on that channel to change the sound
that they are playing.
Note; The definition of "program" varies widely between
MIDI devices. To verify terminology, consult the
manual for the device being controlled.
Using [VOICE SELECTOR]
When the [VOICE SELECTOR] is used to select the
voices for the Single and Layer modes, MIDI Program
Numbers 0 to 20 are transmitted using the format
shown in the table on page .
Note: The above procedure always transmits a PROGRAM
CHANGE request, regardless of the PROGRAM
CHANGE CANCEL setting. {See "inhibiting PRO­
GRAM CHANGE Requests" below.)
inhibiting PROGRAM CHANGE Requests
When the PROGRAM CHANGE function is set to
OFF, all incoming and outgoing PROGRAM
CHANGE messages are ignored.
Note: This function does not affect selection of internal
voices from the front panel [VOICE SELECTOR]
switches.
To change the setting, hold down the TRANS­
POSE/FUNCTION switch and press the
E.PIANO switch.
E.PIANO lamp off PROGRAM CHANGE ON
E.PIANO lamp on PROGRAM CHANGE OFF
Note: You can disable the Program Change function inde­
pendently for each MIDI channel (channels 1 to 16).
The piano remembers the setting for each channel
(so long as power remains on), and reinvokes the
setting each time you come back to that channel.
Note: When the power is turned on, the C-350/C-150 al­
ways starts with the PROGRAM CHANGE function
ON.
