Troubleshooting

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

The power doesn’t come on

Is the adapter connected and plugged in correctly? (p. 8)

The buttons do not work

Is the panel locked (p. 26)? Turn the power off, then back on.

No sound is heard

Is the volume of the ep-760 turned all the way down? (p. 9)

Are headphones plugged in? (p. 9)

Has a plug remained connected to one of the Phones jacks? When headphones are connected, the speakers stop playing.

Is Local Off selected? When Local Control is set to OFF, no sound is produced by playing the keyboard. Set Local Control to “On” (p. 29)

No sound is heard (when a MIDI instrument is connected)

Have all devices been switched on?

Are the MIDI cables connected correctly?

Does the MIDI channel match the connected instrument? (p. 28)

Sounds are heard twice (doubled) when the keyboard is played

Is the ep-760 in Dual mode? (p. 11)

When the ep-760 is connected to an external sequencer, set it to the Local OFF mode (p. 29).

Alternatively, the sequencer could be set so its MIDI Thru feature is OFF.

The tone has changed in Split or Dual mode.

If you use Dual or Split mode with a Tone button for which tone number “3” or “4” is selected, tone number “1” will be selected for that Tone button (p. 11).

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. 105.

Tone doesn’t change

Is the panel locked? (p. 26)

Turn the power off, then back on.

Are the indicators for the [Metronome] and [Beat] buttons flashing? The Function mode is selected. Press the [Metronome] or [Beat] button to exit function mode (p. 24, p. 28).

Not all notes you play are sounded

The maximum number of notes that the ep-760 can play simulta- neously is 64.

Frequent use of the damper function when playing along with a song may result in performance data with too many notes, causing some notes to drop out.

The tuning or pitch of the keyboard or song is off

Have you set Transpose? (p. 16)

Are the settings for the “Temperament” and “Stretch Tuning” cor- rect? (p. 24)

Is the setting for the “Master Tuning” correct? (p. 24)

Song doesn’t play back/Only the sound of a particular instrument in a song does not play

Are the indicator for the Track buttons ([1] and [2] buttons) extin- guished? (p. 19)

If the button indicator is off, the music on that track is not heard. Press the track button so the indicator is illuminated.

Can’t record

Has one of the track buttons for recording been selected? (p. 22)

Tempo of recorded song or metronome is off

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 performances. The tempo of the metronome will also change in the same way.

If you record additional material without erasing the previously re- corded song, the song will be recorded at the first-recorded tempo. Please erase the previously recorded song before you re-record.

(p. 23)

The recorded performance has disappeared

Any performance that has been recorded is deleted when the pow- er to the ep-760 is turned off. A performance cannot be restored once it’s been deleted.

Reverberation still audible even with Reverb turned off

Since the ep-760’s piano sounds faithfully reproduce the sense of spaciousness and reverberation of an actual acoustic piano’s sound, a certain amount of reverberation is still perceptible, even with the Reverb effect deactivated. This only applies if you connect the sup- plied DP-2 footswitch to the Pedal [Damper] socket.

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, regard- less of the damper pedal. There is a difference in the timbre as well. Roland pianos faithfully simulate such characteristics of the acous- tic piano. On the ep-760, 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 effervescent piano tones feature an ample high-end component, which may make the sound appear to have metallic reverberation added. Since this reverberation be- comes particularly audible when supplemented 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 ep-760) 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 ep-760 to resonate. Resonance can also occur with fluorescent 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 surfac- es.

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 ep-760) 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

Are you using a connection cable that contains a resistor? Use a connection cable that does not contain a resistor.
