Trouble Shooting
The Tone has
changed.
When a performance made along with a Music
Files tune has been recorded, recording the
performance to button [1/User] may make the
Tones for buttons [3/Left] and [4/Right]
change as well.
The recorded
performance
has
disappeared.
Any performance that has been recorded is
deleted when the power to the HPi-7 is turned
off or a song is selected. A performance cannot
be restored once it’s been deleted.
Lyrics are not
indicated
properly in the
display.
With some music files, the lyrics cannot be
displayed correctly.
In the notation screen, some lyrics or notes
could extend beyond the edges of the screen,
and not be displayed.
Notation is not
indicated
properly in the
display.
If you select a part that does not contain
performance data, notes will not be displayed
in the notation. Change the part that is
displayed (p. 47).
The notation screen feature is particularly
unsuitable for the display of difficult, complex
musical works that demand accurate notation.
Refer to “Some notes on the notation screen”
(p. 15).
In the notation screen, some lyrics or notes
could extend beyond the edges of the screen,
and not be displayed.
Song becomes
unstable
In certain cases, such as when playing songs on
disks, the song may lag when excessive
amounts of performance data are used.
Depressing a
pedal has no
effect, or the
pedal effect
doesn’t stop.
Is the pedal connected correctly?
Make sure the pedal cord extending from the
stand is securely connected to the pedal jack on
the rear of the unit (p. 9).
Has a different function been assigned to the
pedal?
See “Changing the function of the pedals
(Pedal)” (p. 56).
The pedal
rattles
Adjust the adjuster underneath the pedal so
that the pedal presses firmly against the floor
surface (p. 11).
Reverberation
still audible
even with
Reverb turned
off
Since the HPi-7’s piano sounds faithfully
reproduce the sense of spaciousness and
reverberation of an actual acoustic piano’s
sound, a certain amount of reverberation is still
perceptible, even with the reverb effect
deactivated.
In the upper
range, the
sound changes
abruptly beyond
a certain key
On an acoustic piano, notes in the upper one
and a half octaves of the keyboard continue to
sound until they decay naturally, regardless of
the damper pedal. There is a difference in the
timbre as well. Roland pianos faithfully
simulate such characteristics of the acoustic
piano. On the HPi-7, the range that is
unaffected by the damper pedal will change
depending on the Key Transpose setting.
Case Cause/Remedy
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 HPi-7) 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 HPi-7 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 HPi-7) would be suspect.
Consult your Roland dealer or nearest
Roland Service Center.
The volume
level of the
instrument
connected to
Input jacks is
too low.
Could you be using a connection cable that
contains a resistor?
Use a connection cable that does not contain a
resistor.
Titles of songs
on floppy disk
not being
displayed
Has the song name data (Sequence/Track
Name Meta Event) been entered in the file?
Song titles are not displayed if the song name
data is blank or consists exclusively of spaces.
Is the file name no more than eight single-byte
characters?
Have any double-byte characters (such as
Japanese Hiragana or Kanji characters) been
used in the file name? This instrument does not
display double-byte characters. For characters
that can be used with this instrument, refer to
p. 43.
Is "MID" used as the extension? The song
cannot be treated as song data if a different
extension is used.
