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 KR) 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 KR 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.

Here, a different cause (such as resonance
produced by the KR) would be suspect.

Roland Service Center.

as rewind or fast forward) become
unavailable.
There is a slight
delay before
playback of a song
on external

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.
