exceeded, so that the pitch does not rise as far as
you expect, but will stop rising at a certain point.
Additionally, if differing upper pitch limits are
used for the waves of a Patch that uses multiple
tones, it may stop being heard in MONO. When
making large pitch changes, set the Legato
Retrigger parameter to “ON.”

The notes sound strange in the upper part.

• Sometimes when playing the keys in the upper
part, the sound may stop, or the pitch may stop
rising; or with certain keys, there may be
intermittent noise. This occurs mainly when the
MV-8000's upper pitch limit is exceeded, so this
issue doesn't arise in the ranges normally used.
But, in any case, it does not indicate a
malfunction.

The volume level of the instrument connected to
MV-8000 is too low.

• Could you be using a connection cable that
contains a resistor? Use a connection cable that
does not contain a resistor.

Issues Related to Effects

Effects not applied.

•

\

The “MFX,” “CHO,” “REV” effect switches
located in the EFFECT screen may have been
turned off.
Press [EFFECTS]/[F4 (Fx On/Off)] to turn them
on.
• Are the various effect settings correct?
If the send level of each effect is set to 0, the effect
will not be applied. Check the settings.
• If Output Assign is set to other than “MFX,” the
Multi-effects sound will not be output.

I want to change the connection order of the effect
algorithm.

• You can't change the connection order of the
effect algorithm. Effects can only be switched
on/off.

The Modulation or other controller is always on.

• Check the Patch Control settings.
The MV-8000 allows you to use the Patch Control
to control Patches in real time. The Patch Control
functions as the control source for the Control
Change and other MIDI messages received by the
MV-8000, and makes changes to the various
Patch parameters based on these messages.
Depending on these settings, the MV-8000 may be
responding to MIDI messages sent from external
MIDI devices, and may result the Patches
sounding different than intended.

Issues Related to Sequencer

Can’t record the sequence data

• Is there enough Sequence Memory capacity?

After recording, the song does not sound when I play it
back.

• Have the tracks been muted?
Defeat muting.

The tempo is different than the last time I played back
the song.

• If a song is played back after the tempo is
changed, then the new tempo is not saved unless
the song is saved to disk. Conversely, the
previous tempo will be erased when you save the
song. When saving songs, carefully check the
current tempo.

Data supposed to be present does not appear in
microscope.

• Are the wrong tracks selected?
• In View Filter, is any data set not to be displayed?

After using a MIDI sequencer to play a song, sounds
stopped playing, and no sound is played even when
Program Changes are sent.

No sound is played if the patch library is not one
designated by the MV-8000 with program change.
Try resending the correct the program change of the
patch library.

Performances are sluggish, or have interruptions.

• Problems of sluggish and interrupted
performances can crop up very easily when the
sequencer or sound generator used for the
performance has to handle heavy data loads.
Main causes and possible corrective measures are
considered below.
• Are more than 64 voices playing simultaneously?
Reduce the number of voices. The composition of
MV-8000 Patches is such that up to eight Waves
may be used for one Patch. When using such
Patches, even though only one sound may be
heard, it is actually eight sounds that are being
played simultaneously. In addition, with certain
sounds like continuous sounds with long
releases, even though the actual sound may not
