The pedals are not functioning, or function intermittently

❍Are the pedals connected properly? (p. 9)

Can’t Record

❍Is Panel Lock on? (p. 22)

❍Is the [Demo] button’s indicator lit?

Press the [Demo] button; the button’s indicator goes out (p. 11).

❍The metronome sound or count sound is not recorded.

The recorded performance has been deleted

❍The performance data that you recorded will disappear when the power of the ep-90/70 is turned off (p. 19).

❍If you record again after recording, the first-recorded performance will be erased (p. 19).

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 ep-70/90, the range that is unaffected by the damper pedal will change depending on the Key Transpose setting.

<When the ep-90/70 is connected to an external device>

No sound is produced

❍Is the power to all equipment turned on?

❍Are the connections between ep-90/70 and the MIDI sequencer or the other external devices correct?

(p. 24, p. 25)

❍Is the Omni On/Off setting correct? (p. 27)

Strange sounds (or two sounds) are produced when the ep-90/70 is played

❍With the sequencer’s “Thru” function on, the same notes may be sounded twice. Set the ep-90/70 to Local off

(p. 26).

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.
