Troubleshooting

Low notes sound wrong, or are

buzzy

If you don’t hear this in headphones:

Performing at high volumes may cause the speakers or objects near the DP-

990 to resonate. Fluorescent lights or glass doors may also resonate

sympathetically. In particular, this is more likely to occur for lower notes and

higher volumes. You can take the following measures to minimize resonances.

• Locate the speakers 10–15 cm away from walls or other surfaces.

• Keep the volume down.

• Move away from the objects that are resonating.

If you hear this in headphones:

It is likely that there is some other reason. Please contact your dealer or a

nearby Roland service center.

—

If you set the volume to the maximum setting, the sound may be distorted

depending on how you perform.

If this occurs, turn down the volume.

p. 20

Song does not play correctly

Song won’t play

Could the screen be indicating “dEL”?

You can’t play back an internal song if internal memory contains performance

data you recorded. Erase the performance data you recorded before you play

back the song.

p. 43

Only the sound of a particular

instrument in a song does not

play

Could a track be muted?

If the button indicator is out, the music on that track is not heard. Press the track

button so the indicator is illuminated.

p. 46

Can’t play back a song saved in

USB memory

Audio files of the following format can be played back.

• File extension “.WAV”

• 16-bit linear

• “44.1 kHz” sampling rate

p. 44

Is the filename extension “MID”?

Files with other filename extensions cannot be handled as song data.

—

Song tempo becomes unstable

When playing a song from USB memory, the tempo may become unstable if

there is an excessive amount of performance data.

—

Can’t record

Has one of the track buttons for recording been selected?

p. 54

p. 57

The recorded performance

disappeared

Your recorded performance will disappear if you switch off the DP-990’s

power or select a song.

There is no way to recover the lost performance. Before you turn off the power,

save your recorded performance in internal Memory.
