Troubleshooting
If the system does not operate as you expect, please check the following points first. If this does not resolve the problem, please
contact the nearest Roland service center.
■ Problems with the power supply
Problem
Power does not turn on
■ Problems with the sound
Problem
No sound / Volume is too
low
No sound when you
strike the velocity pads
●
Is the MV-8800's AC power cord correctly connected to an AC outlet and to the MV-8800's
power inlet?
●
Are the audio cables connected correctly?
●
Could an audio cable be broken?
●
Has power to the connected amp and/or speakers been switched on? Could their volume
be turned down?
●
Could the volume have been turned down by the MASTER knob or PHONES knob?
●
Could multi-timbre sampler mode be on?
➔
If multi-timbre sampler mode is on, the internal sound generator will not sound.
If you want to play sounds by striking the velocity pads, access the MIDI screen (Screen
Guide; p. 177), and turn the Multi Timbre Sampler Mode setting Off.
●
You don't hear sounds after creating a new project
➔
When you create a new project, the newly created project will not immediately play sounds
unless you copy instruments, audio phrases, or pattern settings from the currently selected
project.
When you create a new project, use the CREATE NEW PROJECT screen (Screen Guide;
p. 166) to make the appropriate settings in Copy From Current Project.
If you want to play new sounds in your new project, start by preparing your sounds.
☞ IMPORT screen (Screen Guide; p. 219), SAMPLING screen (Screen Guide; p. 209)
●
A specific velocity pad doesn't produce sound
➔
Use the PAD BANKS popup (Screen Guide; p. 5) to check whether a sound (partial, audio
phrase, or pattern) is assigned to that velocity pad and to other pad banks.
If you want to newly assign a sound, make the desired assignment.
• Assigning a partial
☞ PATCH QUICK ASSIGN popup (Screen Guide; p. 216)
• Assigning an audio phrase
☞ AUDIO PHRASE QUICK ASSIGN popup (Screen Guide; p. 214)
• Assigning a pattern
☞ ASSIGN TO PAD popup (Screen Guide; p. 100)
●
Could the volume be turned down by the MASTER knob or PHONES knob?
●
Could the fixed velocity level value be set to a low value?
➔
If [FIXED VELOCITY] is lit, the sound will play at the velocity value specified by the Fixed
Velocity Level setting in the PAD screen (Screen Guide; p. 174), regardless of how strongly
you actually strike the pad.
●
Does the performance data of the track have an appropriate output destination?
➔
In the SONG screen or PATTERN screen, the sounds played by the pads are determined by
the type of the current track.
In the TRACK PARAMETER popup (Screen Guide; p. 11–15), set the Output Assign or MIDI
parameter to the part number or MIDI channel you want the track to play.
