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

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.

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.

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:
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
instruments near the HPi-7 to resonate.
