Pressing the expression pedal while
playing back ATELIER performance
data produces a crackling noise
The expression pedal function is set to
“PEDAL+COMPOSER” during
playback of ATELIER performance
data.
When this setting is used, moving the
expression pedal while playing back
ATELIER performance data may create
a difference between the expression
pedal information in the performance
data and the volume as set with the
expression pedal, which can result in
this kind of sound being produced.
Set the expression pedal function to
“PEDAL” during playback.
Even though you press only one key,
a multiple number of notes sound
Harmony Intelligence is at ON.
Turn “Harmony Intelligence” off.
Chord Intelligence is turned ON.
Turn “Chord Intelligence” off.

Simultaneously press the Transpose [-]
[+] buttons to cancel the transposition

used to raise the overall volume
excessively.
Use the [Master Volume] slider to lower
the overall volume.
The Bass Range Sounds Odd, or
There Is a Vibrating Resonance
When listening through speakers:
Playing at loud volumes may cause
instruments near the ATELIER to
resonate. Resonance can also occur
with fluorescent light tubes, glass
doors, and other objects. In particular,
this problem occurs more easily when
the bass component is increased, and
when the sound is played at higher
volumes.
Use the following measures to suppress
such resonance.
• Place speakers so they are 10-15 cm
from walls and other surfaces.
• Reduce the volume.
• Move the speakers away from any
resonating objects.

When listening through headphones:
Here, a different cause (such as
resonance produced by the ATELIER)
would be suspect.
Consult your Roland dealer or nearest
Roland Service Center.
