*If a message appears during operation, consult the following section “Error Messages” (p. 218).

Cannot Turn the Power On

Is the XV-88’s AC cord properly connected to the AC outlet and the XV-88? (Quick Start; p. 16)

No Sound

Is the power turned on for the other devices connected to the this unit? Is the volume level turned down?

Is the VOLUME slider turned all the way down?

Have connections been made correctly?

When using the XV-88 by itself, connect audio cables or headphones (Quick Start; p. 16).

If using the XV-88 connected to a computer, use a computer cable or MIDI cable to make the connection to the computer (p. 208). Then, connect audio cables or headphones (Quick Start; p. 16).

Can you hear sound through headphones?

If there is sound in the headphones, it is possible that the connection cables are broken, or that the amp or mixer is malfunctioning. Check the connection cables and other devices once again.

If you do not hear sound when you play the keyboard, check whether the Local Switch is turned OFF.

Turn the Local Switch on by the following parameter.

In Patch/Rhythm Set Mode

Local parameter (SYSTEM/MIDI/PATCH MIDI) (p. 170)

In Performance Mode

Local parameter (SYSTEM/MIDI/PERFORM MIDI) (p. 169)

Local parameter (ZONE/MIDI/MIDI) (p. 60)

In Layer Performance mode, does the MIDI transmit channel match the MIDI receive channel?

Check that the MIDI transmit channel (Channel parameter (ZONE/MIDI/MIDI)) of the Zone matches the MIDI receive channel (Channel parameter (PERFORM/MIDI/MIDI)) of the Part (p. 52, p. 59).

Have all tones in the patch been turned off?

Press TONE SWITCH [1]–[4], getting the indicators to light (p. 32).

Are the Tone, Patch and Part level settings excessively low?

Check the level settings of each Tone, Patch and Part with the following parameters.

Tone level

Level parameter (PATCH/TVA/TVA) (p. 90)

Patch level

Level parameter (PATCH/COMMON/PATCH LVL&PAN) (p. 70)

Part level

Level parameter (PERFORM/PART/SETTING) (p. 53)

Are the effect settings correct?

Check the Effect settings ON or OFF (p. 105), in the Effect Balance or Level.

Are the output destination settings correct?

Check the Output Assign settings (p. 108, p. 109, p. 113, p. 116, p. 158, p. 160, p. 194, p. 195).

Is the Wave Expansion Board properly installed?

When selecting the settings that stipulate the use of XP- A–D waves, Patches, or Rhythm Sets, check that the specified Wave Expansion Board is installed properly in the specified slot (Quick Start; p. 4, p. 10).

Has the volume been lowered by pedal operations or by MIDI messages (volume messages or expression messages) received from an external MIDI device?

Use the Panic function to raise the volume (p. 48).

If you are in Performance mode, access the INFO display (PERFORM/INFO) to check the settings of the Volume message (Vol) and Expression message (Exp) parameters, and make the appropriate settings (p. 56).
