MODX+ Owner’s Manual
54
You can connect to an external MIDI device using a commercially available MIDI cable or USB cable. This allows you to control
an external MIDI device from MODX+, or play the tone generator of the MODX+ with an external MIDI keyboard or sequencer.
This section describes the settings required to use the device as intended while connecting an external MIDI device. For details
on specific connection examples, refer to the Reference Manual.
Connecting to an external MIDI
device with the MIDI [IN], [OUT]
terminals
When connecting to an external MIDI device using the MIDI
[IN] and [OUT] terminals, the following two settings related
to MIDI transmission/reception must be set correctly to
operate the device as intended.
MIDI IN/OUT
Determines whether MIDI communication with an external
device is handled through the MIDI [IN], [OUT] terminals or
the [USB TO HOST] terminal.
The setting display is called up by the [UTILITY] button 
[Settings] tab  [MIDI I/O] tab  “MIDI IN/OUT.”
NOTE
For an external MIDI device connected via the [USB TO DEVICE]
terminal, MIDI communication is always possible regardless of this
setting.
MIDI I/O Mode
Determines the rules by which channels transmit the data of
each Part and which Part receives the data received by each
channel, when communicating with an external MIDI device.
The setting display is called up by the [UTILITY] button 
[Settings] tab  [Advanced] tab  “MIDI I/O Mode.”
Connecting to an external MIDI
device with the [USB TO DEVICE]
terminal
You can connect an external MIDI device (such as a MIDI
keyboard) to the [USB TO DEVICE] terminal and treat it as if
it were a keyboard built into the MODX+ itself.
MIDI devices available
• USB class compliant MIDI devices
USB MIDI keyboard, etc.
• Yamaha MIDI devices whose compatibility has
been confirmed
CP1, CP4/40 STAGE, CP88/73, MODX, MONTAGE,
MOTIF XF, MOXF, MX, reface, YC
NOTICE
The rating of the [USB TO DEVICE] terminal is a maximum of 5V/
500mA. Do not connect USB devices having a rating above this,
since this can cause damage to the instrument itself.
Special notes concerning MIDI
communication
MIDI communication with a device connected via the [USB
TO DEVICE] terminal follows special rules that allow the
device to behave like a built-in keyboard.
• MIDI communication is one-way only (sent from the
external MIDI device and received by the MODX+).
• All MIDI data is received regardless of the “MIDI IN/OUT,”
“MIDI I/O Mode,” and “MIDI I/O Ch” settings.
• For Parts with Keyboard Control set to on, data received
on all corresponding channels is shared. For example,
when Keyboard Control for Parts 1 to 3 are set to on, data
received from any of channels 1 to 3 will be delivered to all
Parts 1 to 3.
• Each Part with Keyboard Control set to off receives the
data of only the corresponding channel for the Part.
• Only when “MIDI I/O Mode” is “Single,” some particular
Control Change messages sent to the channel specified
by “MIDI I/O Ch” setting are not relayed to each Part but
be received as Common parameters. In this regard, this is
the same way as communication via the MIDI [IN], [OUT]
terminals and the [USB TO HOST] terminal. For details on
the applicable Control Change messages, refer to the
“MIDI I/O Mode” section of the Reference Manual.
Connecting External MIDI Instruments
MIDI
For using the MIDI [IN], [OUT] terminals.
USB
For using the [USB TO HOST] terminal.
Multi
This is one-to-one correspondence between each
Part and each channel. For example, Part 1 data is
sent and received on channel 1 and Part 16 data is
sent and received on channel 16.
Single
Data of all Parts with Keyboard Control set to on is
sent and received on one specified channel. Data
of Parts with Keyboard Control set to off is not sent
or received.
To specify which channel is used to send and
receive data, set the “MIDI I/O Ch.”
Hybrid
Data for all Parts with Keyboard Control set to on is
sent and received in the same way as when
“Single” is set.
Data on the Part where Keyboard Control set to off
is sent and received in the same way as when
“Multi” is set.
