Roland MP-70 Benutzerhandbuch

 

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 simu-
late such characteristics of the acoustic piano. 
On the MP-70, the range that is unaffected by 
the damper pedal will change depending on 
the Key Transpose setting.

 

A High-pitched 

whine is produced

 

When listening through headphones: 

Some of the more flamboyant and effer-
vescent piano tones feature an ample 
high-end component, which may make 
the sound appear to have metallic rever-
beration added. Since this reverberation 
becomes particularly audible when sup-
plemented 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 MP-70) 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 MP-70 to resonate. 
Resonation can also occur with fluores-
cent 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 MP-70) 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.

User Song. Stores recorded performances (p. 26).

 

The “.” in the display indicates that there is performance material already 
recorded (p. 26).

 

 

This appears when a song with a pickup (a song that does not start on the 
first beat) is played back.

 

This appears when you attempt to delete a recorded song (p. 25, p. 30). 

 

The amount of performance information is too large, and further 
recording is not possible.

 

A problem such as a loose MIDI cable occurred. Make sure the MIDI 
cables are correctly hooked up.
