Troubleshooting
The sound is not played correctly
If you layer the same type of sound (for 
example, Strings 1 and Strings 5), or 
play an octave-shifted organ sound, 
the timing at which you play a note or 
the phase relationship between the two 
sounds may affect the way in which the 
sounds are heard, but this is not a 
malfunction.
You are layering sounds of the same 
type (e.g., Strings 1 and Strings 5).
Alternatively, you are playing an 
organ sound with Octave Shift.
This is not a malfunction.

The Bass Range Sounds Odd, or 
There Is a Vibrating Resonance
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.
