Roland DP-900 用户手册

 

If you think there’s a problem, read this first.

 

Is the power cord connected and 
plugged in correctly? (p. 11)

 

Is the tone or panel locked? (p. 33)
Turn the power off, then back on.

 

Is the volume level of the DP-900 
turned all the way down? (p. 14)
Are headphones plugged in? (p. 12)
Has a plug remained connected to the 
Phones jack?
When headphones are connected, the 
keyboard’s speaker stops playing.
Is Local Off selected? (p. 36)
Set Local Control to “ON”.

 

Have all devices been switched on?
Are the MIDI cables connected cor-
rectly?
Does the MIDI channel match the con-
nected instrument? (p. 35)

 

Is the DP-900 in Dual play? (p. 17)
When the DP-900 is connected to an 
external sequencer, set it to the Local 
OFF mode (p. 36). 
Alternatively, the sequencer could be 
set so its MIDI Thru feature is OFF.

 

If you use Dual play or Split play with 
a Tone button for which tone number 
3 or 4 is selected, tone number 1 will be 
selected for that Tone button (p. 17).
Some tones assign the tone that had 
been selected before you pressed the 
[Split] button to the left hand area of 
the keyboard. Please refer to “Tone 
List” (p. 40).

 

Is the tone or panel locked? (p. 33)
Turn the power off, then back on.
Are the indicators for the [Metronome] 
and [Beat] buttons flashing?
Setting of functions is in progress. 
Press the [Metronome] or [Beat] but-
ton to exit function mode (p. 31, p. 35).

 

The maximum number of notes that the 
DP-900 can play simultaneously is 64. 
Frequent use of the damper pedal 
when playing along with a song may 
result in performance data with too 
many notes, causing some notes to 
drop out.

 

Have you set Transpose? (p. 22)
Are the settings for the “Tempera-
ment” and “Stretch Tuning” correct? 
(p. 32)
Is the setting for the “Master Tuning” 
correct? (p. 31)

 

Are the indicator for the Track buttons 
([1] and [2] buttons) extinguished? (p. 
25) 
If the button indicator is out, the music 
on that track is not heard. Press the track 
button so the indicator is illuminated.

 

Has one of the track buttons for re-
cording been selected? (p. 28–p. 29)

 

If you select an internal song in which 
the tempo changes during the song, 
and then record, the tempo will 
change in the same way for the perfor-
mances. The tempo of the metronome 
will also change in the same way.
If you record additional material with-
out erasing the previously recorded 
song, the song will be recorded at the 
first-recorded tempo. Please erase the 
previously recorded song before you 
re-record (p. 30).

 

When an internal song is played back, 
the metronome sounds the ordinary 
metronome sound.
When a recorded performance is 
played back, the metronome sounds 
the sound that was selected when the 
recording was made.

 

Any performance that has been re-
corded is deleted when the power to 
the DP-900 is turned off. A perfor-
mance cannot be restored once it’s 
been deleted.

 

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. 
12).

 

Since the DP-900’s piano sounds faith-
fully reproduce the sense of spacious-
ness and reverberation of an actual 
acoustic piano’s sound, a certain 
amount of reverberation is still percep-
tible, even with the reverb effect deac-
tivated.

 

The sound may distort if the volume is 
turned up too much. Adjust the vol-
ume with the [Volume] knob (p. 14).
Also, with certain tones the sound can 
seem to be distorted.
