Troubleshooting
If no sound can be heard, or if the unit does not perform as you expect, check the following points first. If this does not resolve the problem,
contact your dealer or a nearby Roland service station.
* If a message appears during operation, consult the following section
Error Messages
(p. 137).
Problem
Cause Action
No sound
Is the VOLUME lowered?
Check the VOLUME knob, and the volume settings on the connected amp/mixer,
etc.
Have connections been made correctly? If there is sound in the headphones, it is possible that the connection cables are bro-
ken, or that the amp or mixer is malfunctioning. Check the connection cables and
other devices once again.
Is the MIDI receive channel correct? Make sure that the MIDI transmit channel of the connected device matches the re-
ceive channel of the XV-5050 (p. 19).
Are the Tone, Patch and Part level settings exces-
sively low?
Check the level settings of each Tone, Patch and each Part. (Tone p. 48, Patch p. 40,
Part p. 65)
Are Tones or Parts turned off? Check the on/off settings of each Tone and each Part. (Tone p. 39, Part p. 63)
Are the key range settings correct? Check the key range settings of each Tone and each Part. (Tone p. 41, Part p. 64)
Has the volume been lowered by volume/ex-
pression messages received from an external de-
vice?
The volume will return to normal when the power is turned on once again. When a
Performance is selected, the reception status for each type of message can be viewed
in the [INFO] screen (p. 67).
Are the effect settings correct? Check settings such as Effect On/Off (p. 69), and Effect Balance and Level (pp. 75–
103).
Are the output destination settings correct? Check the Output Assign and MFX Output Assign settings. (p. 74)
Is MIDI-USB Thru turned on? Turn the MIDI-USB Thru parameter off, or turn on the MIDI Thru parameter in the
connected computer (p. 109).
Pitch is wrong
Is the Master Tune setting correct?
Check the setting. (p. 110)
Is Scale Tune selected? Check the setting. (p. 110)
Are the pitch settings for each Tone and each
Part correct?
Check each setting. (Tone p. 45, Part p. 66)
Have pitch bend messages received from an ex-
ternal device caused the pitch to “stick”?
The pitch will return to normal when the power is turned on. If a Performance is se-
lected, the [INFO] screen (p. 67) allows you to check the reception status of each type
of messages.
Effects do not apply
Are MFX, CHORUS, and REVERB turned off?
Hold down [SHIFT] and press [PATCH FINDER] to check each setting. (p. 69)
Are the various effect settings correct? If the send levels to each effect are at 0, effects will not apply. Check each setting. (p.
74)
Even if the send level to each effect is above 0, effects will not apply if the MFX Out-
put Level, Chorus Level, and Reverb Level are set to 0. Check each setting. (p. 74)
If Output Assign is set to PATCH for each Part of the Performance, the sound will
be output according to the Output Assign settings of the Patch (for each Tone) which
is assigned to those Parts. This means that if the Output Assign of (each Tone in) the
Patch is set to PATCH, the MFX sound will not be output. (p. 40)
MIDI messages are
not received correctly
Are the receive channel and receive switch set-
tings correct?
Check the settings for the MIDI receive channel (p. 108) and the various switches for
reception of MIDI messages (p. 108).
Are the exclusive receive settings correct? In order for system exclusive messages to be received, the Device ID Number must
match that of the transmitting device, and the System Exclusive receive switch must
be on. (p. 108) Also, if you wish to rewrite data in the USER group, the System Ex-
clusive message Protect Switch must be turned off as well. (p. 105)
Is the DEMO PLAY screen displayed? When the DEMOPLAY screen is displayed, MIDI messages received from an exter-
nal device will be ignored.
Song data does not
playback correctly
Are you playing back from the middle of the
song?
The beginning of a General MIDI score song contains a GM System On message. In
some cases, a General MIDI Score cannot be played back correctly unless this mes-
sage is received.
Are you playing back GS format song data? Since the XV-5050 is a General MIDI system compatible sound source, there may be
cases in which GS format song data will not playback correctly.
Is the Patch mode selected? When song data is played back in the Patch mode, only the sound of a single Part is
played. Change to the Performance mode, then play the song data.
