What is MIDI?
MIDI, is the abbreviation of Musical Instrument Digital
Interface. It is an international standard that was created
to connect and transfer data between electronic musical
instruments, computers and other devices.
What can you do with MIDI?
Thanks to MIDI, you can use the SP-280 to control other
instruments, use other instruments to control the SP-280,
and use a sequencer to create complex musical pieces.
When you use the SP-280 keyboard or pedal, or select a
sound, the notes, pedal activation and change in sound are
transmitted to another instrument, or are recorded by a
sequencer.
Connections
Commercially available MIDI cables are used to transfer
MIDI data. Connect these cables from the MIDI connectors
of the SP-280 to the MIDI connectors of the external MIDI
device that you want to exchange data with. There are two
types of MIDI connector.
MIDI IN connector
This connector receives MIDI messages.
The MIDI IN connector lets you play the SP-280’s sounds
from an external MIDI device (e.g., MIDI keyboard or se-
quencer). Use a MIDI cable to connect the SP-280’s MIDI IN
connector to your external MIDI device’s MIDI OUT con-
nector.
MIDI OUT connector
This connector transmits MIDI messages.
The MIDI OUT connector lets you control an external
MIDI device using the MIDI messages transmitted from
the SP-280. Use a MIDI cable to connect the SP-280’s MIDI
OUT connector to your external MIDI device’s MIDI IN
connector.
MIDI function mode
When the SP-280 is turned on, the MIDI parameters are set
to transmission channel 1, all reception channels (1–16),
Local On and Omni Off.
These settings can be changed from the MIDI function
mode.
Setting procedure for parameters in the MIDI
function mode
1. Hold down the FUNCTION button.
The FUNCTION LED blinks.
2. Press the sound button corresponding to the desired
parameter.
The current setting appears in the display.
3. Specify the desired setting.
4. After specifying the desired settings, press the
FUNCTION button to return to the mode for playing.
The FUNCTION LED turns off.

When the SP-280 is turned off, all parameters return to
their default settings.
Changing the MIDI channels
Data can be transmitted and received on MIDI channels 1
through 16 (C01–C16).
When the SP-280 is turned on, transmission channel 1 (C01)
is automatically selected.
• After entering the MIDI function mode, the LED for
the PIANO1 sound button lights up.
When the MIDI function mode is entered, the MIDI
channel setting normally appears.
To specify the MIDI channel setting after changing
other settings in the MIDI function mode, press the
PIANO1 button.
In the Layer or Partner modes, selecting the transmission
channel specifies the channel for layer 1 or the left side
of the keyboard. The transmission channel for layer 2 or
the right side of the keyboard will automatically be set to
the following channel. For example, if MIDI channel 7 is
selected for the sound of layer 1 or the left side of the key-
board, MIDI channel 8 will automatically be specified for
the sound of layer 2 or the right side of the keyboard. If
MIDI channel 16 is selected for the sound of layer 1 or the
left side of the keyboard, channel 1 will be specified for the
sound of layer 2 or the right side of the keyboard.
Local On/Off
With the Local On setting, playing the SP-280’s keyboard
produces the sounds of the performance as well as trans-
mits MIDI data. With the Local Off setting, playing the
SP-280’s keyboard does not produce the sounds of the
performance; MIDI data is only transmitted. Normally this
parameter is set to Local On (default setting: on).
The Local Off setting should be selected when using the
SP-280 as a master keyboard, for example, to play sounds
from a connected MIDI device (a keyboard, sound module,
etc.). The SP-280 will not produce sound, but the perfor-
mance will be played by the connected MIDI device.
Select the Local Off setting (oFF) when using the SP-280
as a sound module, for example, when the SP-280 is con-
nected to a sequencer with its Echo Back setting (function
that sends back data that the sequencer received) selected
in order to prevent echoing of returned data.
• Enter the MIDI function mode, and then press the
PIANO2 button.
The LED for the PIANO2 sound button lights up, and
the Local On/Off setting (on) appears in the display.
