Using the Sliders to Modify the Sound 
(SOUND MODIFY)
You can use the SOUND MODIFY sliders to modify the sound in real time.
MEMO
 . If you’ve selected a rhythm set when playing a single sound at a time 
(i.e., if the [PERFORM] button is unlit), the ENVELOPE [ATTACK] and 
[RELEASE] knobs and the [CUTOFF] and [RESONANCE] knobs will apply 
to each individual key. When you turn one of these knobs, the currently 
selected key will be indicated (e.g., C4).
 . To change the key to which the eect is to be applied, press a key and 
specify a new key name.
 . If you’re using settings that play more than one tone at a time (i.e., if the 
[PERFORM] button is lit), the target aected by these modications will 
depend on the current settings.

For some sounds, the knobs may not have an eect.
Modifying the tonal character
[CUTOFF] slider
Adjusts the frequency (cuto frequency) at which the lter begins to be 
applied.
Increasing the value brightens the sound; decreasing the value darkens the 
sound.
What is aected by the change
(XPS-10 setting)
Explanation Value
Performance mode The part’s Cuto -64–+63
Patch mode The patch’s Cuto -63–+63
Drum kit
The Cuto for each key 
of the drum kit
0–127
[RESONANCE] slider
Boosts the sound in the vicinity of the cuto frequency, adding a distinctive 
character to the sound.
Increasing the value gives the sound a more distinctive character; 
decreasing the value makes the sound less distinctive.
What is aected by the change
(XPS-10 setting)

Modifying how the volume changes
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 species the way that the volume changes, 
starting when you press a key, and how it decays after you release the key.

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 level:   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
On the XPS-10, you can use the two ENVELOPE sliders to adjust the A 
(Attack) and R (Release) times of the currently selected tone.
[ATTACK] slider
Adjusts the time from when you press the key until the sound reaches the 
maximum level.
Increasing the value slows down the attack of the sound; decreasing the 
value speeds up the attack of the sound.

[RELEASE] slider
Adjusts the time from when you release the key until the sound is no 
longer heard.
Increasing the value lengthens the time over which the sound decays to 
silence; decreasing the value shortens this time.
