Troubleshooting
A High-pitched whine is produced
When listening through headphones:
Some of the more flamboyant and effervescent piano tones feature an ample high-end component, which may make
the sound appear to have metallic reverberation added. Since this reverberation becomes particularly audible when
supplemented by heavy reverb, you may be able to diminish the problem by reducing the amount of reverb applied
to the sound.
When listening through speakers:
Here, a different cause (such as resonance produced by the RM-700) would be suspect. Consult your Roland dealer or
nearest Roland Service Center.
The bass range sounds odd, or there is a
vibrating resonance
When listening through speakers:
Playing at loud volumes may cause instruments near the RM-700 to resonate. Resonation 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 RM-700) would be suspect. Consult your Roland dealer or
nearest Roland Service Center.
If you set the volume to the maximum setting, the sound may be distorted depending on how you perform.
In this case, lower the volume. Alternatively, you can lower the Master Gain (p. 188).

memory, you may find that operations other than playback (such as rewind or fast forward) become unavailable.
There is a slight delay before playback of a
song on external memory starts
There are two types of SMF music files: format 0 and format 1. If the song uses SMF format 1 data, there will be a slight
delay until playback starts. Refer to the booklet that came with the music files you’re using to determine the format
type.
