Introduction
Getting Acquainted with the JD-Xi
Controller section
The controller section is what you use for 
performing.
For example, a performer’s actions such as 
“playing the keyboard” are sent to the sound 
generator section, causing it to produce 
sound.
The controller section of the JD-Xi consists of 
the keyboard, the pitch bend and modulation 
wheels, and the panel buttons and knobs.
Sound generator section
The sound generator section creates the 
sound.
In response to the performance data sent 
from the controller section, this section 
electrically generates the waveform that 
is the basis of the sound, and modies the 
brightness and loudness to produce an 
incredible diversity of sounds.
The JD-Xi’s sound generator section lets you 
use the panel knobs and buttons to instantly 
change various aspects of the sound, such 
as its waveform and pitch, brightness, and 
loudness.
Program
A program consists of four parts: Digital Synth 1, Digital Synth 2, Drums, and Analog Synth.
A program you edited can be saved as a user program (64 programs in each bank E–H).
Tone
You can select one tone for each part.
*  For an analog synth tone, the oscillator, sub-oscillator, and lter sections consist of analog circuits.
Eects section
The JD-Xi contains four eect units. Eect settings are saved within each program (p. 9).
Arpeggio
This function automatically plays an arpeggio according to the keys that you hold down. Arpeggio settings are saved within each program (p. 6).
Pattern sequencer
This function lets you perform while patterns of several measures play back. You can also create your own original patterns and save them in a program (p. 10).
System
This area stores system parameter settings that determine how the JD-Xi operates (p. 12).

Turning On/O the Power
*  Once everything is properly connected (p. 3), be sure to follow the 
procedure below to turn on their power. If you turn on equipment 
in the wrong order, you risk causing malfunction or equipment 
failure.
*  Before turning the unit on/o, always be sure to turn the volume 
down. Even with the volume turned down, you might hear some 
sound when switching the unit on/o. However, this is normal and 
does not indicate a malfunction.
1.  Before turning on the JD-Xi’s power, consider these two questions:
 5 Are your speakers or headphones connected correctly?
 5 Is the connected equipment powered-o?
2.  Turn the [Master Volume] knob on the top panel all the way to the 
left.
3.  Turn on the [POWER] switch located on the rear panel of the JD-Xi.
*  This unit is equipped with a protection circuit. A brief interval 
(a few seconds) after turning the unit on is required before it will 
operate normally.
4.  Switch on power to the connected equipment, and raise the 
volume to an appropriate level.
Turning O the Power
1.  Before turning o the power, consider these two questions:
 5 Have you minimized the volume of the connected equipment?
 5 Have you saved any sounds or patterns that you created?
2.  Turn o the power for all connected audio devices.
3.  Turn o the [POWER] switch of the JD-Xi.
