Using the JD-XA as a MIDI Controller
The JD-XA’s panel operations can be transmitted as MIDI messages from its MIDI
OUT connector or from USB MIDI OUT.
1. Press the [MIDI CTRL] button.
Keyboard performance and panel operations transmit MIDI messages on eight
channels (channels 9–16 by default) that are separate from those used by the
analog parts and digital parts.
When MIDI CTRL is off, the messages are transmitted on the channel settings for the
analog parts and digital parts.
When you press the [MIDI CTRL] button, panel operations will be transmitted using
the channel settings of MIDI CONTROL PART 01–08 (pattern sequencer messages
are always transmitted on channels 1–16).
You can specify the messages transmitted by each knob and slider, and the channel
settings for the MIDI control parts.
& For details of the overall structure, refer to the “JD-XA Structure Diagram”
inside the front cover.
Transmitting MIDI Messages Assigned to Buttons (Trigger Mode)
You can assign MIDI messages to the [01]–[16] buttons so that the assigned MIDI
message is transmitted from the MIDI OUT connector or USB MIDI OUT when you
press the corresponding button. These messages are not transmitted to the internal
sound engine or to the sequencer.
1. Hold down the [Shift] button and press the [MIDI CTRL] button.
The Program No. display changes to “ TrG ,” trigger mode turns on, and the trigger
mode parameters appear.
2. When you press the [01]–[16] buttons, the assigned MIDI messages are
transmitted.
They are transmitted on the channel of the currently selected part.
* To turn trigger mode off, hold down the [Shift] button and press the [MIDI CTRL] button once
again.
Changing the trigger mode settings
1. When trigger mode is on, hold down the [Exit] button and press one of the
[01]–[16] buttons.
The parameters transmitted in trigger mode are shown.
2. Use the cursor [ K ] [ J ] buttons to select the parameter and use the [-] [+]
buttons to change the setting.

Connecting an Analog Synthesizer via the CV/GATE Output
You can connect an analog synthesizer equipped with CV/GATE input jacks, and
control its note on/off or pitch.
Jack Explanation
GATE OUT 1 jack
GATE OUT 2 jack
These jacks output note on/off.
Outputs +5 V.
CV OUT 1 jack
CV OUT 2 jack
These jacks output pitch.
If you’ve made transpose or octave shift settings, this voltage changes
accordingly.
These jacks support OCT/V (it does not support Hz/V).
& For details on these settings, refer to “CV/GATE1/2 OUT” (p. 13).
Connecting a Computer via USB
Here’s how to specify the USB driver that will be used when the JD-XA is connected
to your computer via the USB COMPUTER port.
Download the Driver
In order to use the JD-XA with the “VENDOR” setting, you must download the
driver from the following URL and install it on your computer.
For details on installation, refer to the following URL.
