❍
If you record again after recording, the first-recorded
performance will be erased (p. 22).
Sound is distorted
❍
Is the [Volume] knob set to the maximum position? (p. 11)
Bass notes sound wrong/buzzing or vibration
occurs
❍
If you can’t hear the problem in the headphones:
When playing at high volumes, resonance may occur in
the piano itself or in objects near the piano. At times,
other objects in the room, such as fluorescent lights or
glass doors, could start vibrating. Such phenomenon
becomes more prevalent when sounding the lower
frequencies at high volume. To minimize such unwanted
resonance, please observe the following:
- Locate the instrument so it is 10–15 cm away from
walls.
- Reduce the volume.
- Increase the distance from the object that is
resonating.
❍
If you can hear the problem in the headphones:
The problem may be for a different reason. Please
contact your dealer.
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 MP-500, the range that is unaffected by the
damper pedal will change depending on the Key
Transpose setting.
<When the MP-500 is connected to an
external device>
No sound is produced
❍
Is the power to all equipment turned on?
❍
Are the connections between MP-500 and the MIDI
sequencer or the other external devices correct? (p. 31)
❍
Is the MIDI channel setting correct? (p. 33)
❍
Is the Omni On/Off setting correct? (p. 33)
Strange sounds (or two sounds) are produced
when the MP-500 is played
❍
With the sequencer’s “Thru” function on, the same notes
may be sounded twice. Set the MP-500 to Local off
(p. 32).
The volume level of the instrument connected
to the Input jack is too low.
❍
Could you be using a connection cable that contains a
resistor?
Use a connection cable that does not contain a resistor.
