be audible to you, processing for playing the
sound is still underway, so in these cases as well,
the performance data can differ from the actual
number of voices being played.
• Are you using a Patch that uses a lot of LFO?
Try changing to a different Patch. LFO processing
invariably places a big load on the machine, so
heavy use of the LFO slows down processing for
the MV-8000 overall, which can end up having
affecting the expression of sounds themselves.
• Is the data concentrated at the beginning of the
beats in the sequence data?
Avoid overlapping data with the same timing by
setting an offset of 1–2 ticks instead. Data may
easily become concentrated at the beginning of
the beats in the song data when, for example, the
song data is input using Step Recording, or if the
data is quantized after being input with a
keyboard in real time. Because of this, large
amounts of data are sent to the MV-8000, and the
processing for expressing sounds becomes
bogged down.
• Is there a Program Change at the point where the
song performance is sluggish?
Change the position of the Program Change.
When Program Changes are inserted in songs,
processing time for switching patches increases,
which may then cause the performance to become
sluggish.
• Is there a System Exclusive message at the point
where the song performance is sluggish?
Move the location of the data. System Exclusive
messages contain large amounts of data, thus
placing a heavy burden on sequencers and sound
modules. Try repositioning data and changing
System Exclusive messages to Control Changes
for any data for which Control Changes can be
substituted.
• Is there an Aftertouch or other such large Control
Change at the point where the song performance
is sluggish?
Move the location of the data. If the data is no
longer needed, delete the data. In some cases,
when using a keyboard that features aftertouch to
input data, you may end up inputting huge
amounts of data before realizing this is
happening. Such large amounts of data can place
an excessive load on your sequencer and sound
module.
You can use the Track Edit operation Data Thin to
thin out unwanted messages.
Issues Related to MIDI and
External Devices
No Sound from connected MIDI device.
• Is the instrument set to transmit MIDI messages?
• Have connections been made correctly?
• The MIDI cable is broken. Check your cable.
Exclusive messages are not received.
• Does the Device ID number of the transmitting device match the
Device ID number of the MV-8000?
Check the Device ID parameter.
• The MV-8000 cannot receive exclusive messages other than
MMC. However, exclusive messages can be recorded onto the
sequencer.
When the Bend Range for a Patch is increased (48),
the pitch does not rise sufficiently, even when a MIDI
Pitch Bend message is received.
• While Patch Bend Ranges can be set anywhere
between 0 and 48, when certain Waves in which
the pitch is raised (in the + direction) are used, the
pitch may stop rising at a fixed point, rather than
continuing to go up. Although a value of 12 is
ensured for the upper limit of raised pitches, use
caution when setting the Bend Range above this
figure.
Issues Related to Sampling
External input sound cannot be heard/volume is too
low
• The level of the external input may be lowered.
When you sample, use the SENS knob to adjust the level
appropriately.
• Check Input Level setting.
• The volume of the device connected to ANALOG INPUT may be
lowered.
Adjust it to an appropriate level.
• Are the audio cables connected correctly?
Check the connections.
• An audio cable may be broken.
• Could you be using an audio cable with a built-in resistor?
Use a connection cable that does not contain a resistor (e.g.,
Roland PCS series).
