Symptom
No sound (when a MIDI device is
connected)
Not all the notes you play are
sounded
Notes don't sound right
Sound is not loud enough
Only the high sounds are heard
Pitch of the keyboard or song is
incorrect
Sounds are heard twice (doubled)
when the keyboard is played
The wrong instrument is selected
when you press the [Strings],
[Voice], or [Others] button
Effect does not apply
Reverberation remains even if
You defeat the Reverb effect
The sound of the higher notes
suddenly changes from a certain
key
Are all devices powered on?
Are the MIDI cables connected correctly?
Do the MIDI channels of the HP207 and the connected device match?
The maximum simultaneous polyphony is 128 notes. If you are playing along
with a song and making heavy use of the damper pedal, the number of notes
the HP207 is attempting to produce may exceed the maximum polyphony,
meaning that some of the notes will drop out.
Is the speaker cable connected correctly?
Could you have made Key Transpose settings?
Is the Master Tune setting appropriate?
Is the setting for the Temperament correct?
Is the settings for the Stretch Tuning correct?
Is the HP207 in Dual performance?
When the HP207 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.
INSTRUMENT buttons [Strings] [Voice] [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 [Strings], [Voice], 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.
When you are using Dual performance or Split performance, and different
effects are specified for the two selected tones, the effect will not be applied
to Tone 2 (when using Dual performance) or the left-hand tone (when using
Split performance).
The HP207'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.
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. HP207
faithfully simulate this characteristic of acoustic pianos. On the HP207, the
range that is unaffected by the damper pedal will change according to the key
transpose setting.
