Troubleshooting
Notes don’t sound right
Pitch of the keyboard or song is incorrect
Could you have made Transpose settings? p. 37
Is the Master Tune setting appropriate? p. 58
Is the setting for the Temperament correct? p. 58
Is the settings for the Stretch Tuning correct? p. 58
Not all the notes you play are sounded
The maximum simultaneous polyphony is 128 voices. If you are playing along with a song and making heavy use
of the damper pedal, the number of notes the HP305/HP302 is attempting to produce may exceed the maximum
polyphony, meaning that some of the notes will drop out.

Sounds are heard twice (doubled) when the
keyboard is played
Is the HP305/HP302 in Dual play? p. 31
When the HP305/HP302 is connected to an external sequencer, set the Local Control to off. Alternatively, the
sequencer could be set so its Soft Thru feature is Off.
p. 71
The wrong instrument is selected when you
press the [E. Piano], [Strings], or [Others]
button
Tone buttons [E. Piano] [Strings] [Others] also operate as buttons that select “Recommended Tones.”
With the factory settings, connecting a commercially-available CD-ROM drive to the external memory connector
and selecting a song from a CD-ROM produced for the VIMA (VIMA TUNES) will automatically cause sounds
appropriate for that song to be assigned to the [E. Piano], [Strings], and [Others] Tone buttons, so that you can
select “recommended” sounds by pressing one of these buttons.
You can also make settings so that “recommended” sounds are not automatically assigned.
p. 73
Effect does not apply
When you are using Dual play or Split play, and different effects are specified for the two selected tones, the
effect will not be applied to Tone 2 (when using Dual play) or the left-hand tone (when using Split play).

Reverberation remains even if You defeat the
Reverb effect
The HP305/HP302’s piano sound faithfully simulates the depth and resonance of an acoustic piano, and this may
give the impression of reverberation even if you’ve defeated the Reverb effect.
—
The sound of the higher notes suddenly
changes from a certain key
On an acoustic piano, the approximately one and a half octaves of notes at the top of the keyboard will continue
sounding regardless of the damper pedal. These notes also have a somewhat different tonal character. HP305/
HP302 faithfully simulate this characteristic of acoustic pianos. On the HP305/HP302, the range that is unaffected
by the damper pedal will change according to the key transpose setting.
—
High-pitched ringing is heard
If you hear this in headphones:
Piano sounds that have a brilliant and crisp character contain substantial high-frequency components that may
sound as though a metallic ringing has been added. This is because the character of an actual piano is being
faithfully reproduced, and is not a malfunction. This ringing is more obtrusive if the reverb effect is applied
heavily, so you may be able to minimize it by decreasing the reverb.
If you don’t hear this in headphones:
It is likely that there is some other reason (such as resonances within the unit). Please contact your dealer or a
nearby Roland service center.
—
Low notes sound wrong, or are buzzy
If you set the volume to the maximum setting, the sound may be distorted depending on how you perform.
If this occurs, turn down the volume.
p. 21
If you don’t hear this in headphones:
Performing at high volumes may cause the speakers or objects near the HP305/HP302 to resonate. Fluorescent
lights or glass doors may also resonate sympathetically. In particular, this is more likely to occur for lower notes
and higher volumes. You can take the following measures to minimize resonances.
• Locate the speakers 10–15 cm away from walls or other surfaces.
• Keep the volume down.
• Move away from the objects that are resonating.
If you hear this in headphones:
It is likely that there is some other reason. Please contact your dealer or a nearby Roland service center.

Song does not play correctly
Song won’t play
Could the screen be indicating “dEL”?
You can’t play back an internal song if internal memory contains performance data you recorded. Erase the
performance data you recorded before you play back the song.
p. 44
Only the sound of a particular instrument in a
song does not play
Could a track be muted?
If the button indicator is out, the music on that track is not heard. Press the track button so the indicator is
illuminated.
p. 40
Sound is heard from a muted track
Could the mute volume be set to other than “0”?
If you set this to “0,” the sound of a muted track will be completely inaudible.
