Roland JD-Xi User Manual

Editing the Sound
Adjusting the Brightness and Thickness (FILTER)
The FILTER section contains parameters that
determine the character and distinctive features of
the sound.
[Cuto] knob (Cuto indicator)
This knob species the lter cuto frequency.
The lter whose indicator is lit is selected.
[Type] button
This button switches the lter type (for Analog
Synth, only LPF is available).
[Resonance] knob
Resonance emphasizes the sound in the region of the lter cuto
frequency.
Digital Synth/Drums part
You can use Digital LPF (Low Pass Filter), HPF (High Pass Filter), BPF
(Band Pass Filter), or PKG (Peaking Filter).
Analog LPF is not available.
You can change the slope of the lter.

For details, refer to “Parameter Guide” (PDF).

* Since the Analog LPF uses an analog circuit, the sound might be
aected by the temperature and the state of the power supply.
Adjusting the Loudness and Envelope (AMP/ENV)
The AMP section contains parameters that control the
volume.
The “envelope” is the shape of the volume changes from
when an instrument begins sounding until it decays to
silence. On a keyboard instrument, the envelope species
the way that the volume changes, starting when you press
a key, and how it decays after you release the key.
[Level] knob
This sets the volume.
[Envelope] knob
Turning the knob toward the left produces a shorter sound with a
stronger attack; turning the knob toward the right makes the attack
softer and the release longer.

A: Attack time Time from when you press the key until the sound reaches its
maximum level
D: Decay time Time over which the level decays from the maximum to the
sustain level.
S: Sustain time Volume at which the sound will be sustained while you hold
down the key
R: Release time Time over which the sound decays after you release the key
The [Envelope] knob eectively adjusts the A/D/S/R parameters in a
single operation.
For the Drums part you can edit this individually for each instrument (note).
If you want to edit A/D/S/R separately, enter “Tone Edit” and make
settings ([Menu/Write] button
0
choose “Tone Edit”).

Audio Flow in a Program
A program consists of four parts. The sound of each part is sent to the eect section.
Although the settings of the eect section are shared by the entire program, eects can be turned on/o individually for each part.
