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.

Could you be using a connection cable

Use a connection cable that does not
contain a resistor.
p. 116
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.
