Problems with the sound
Problem Cause
No sound / Volume is too
low
No sound when you
strike the velocity pads
Cause
●
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.

●
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.

Problems with the sound (continued)
Problem
Sound is distorted
Pitch is wrong
When you play legato
from a low range of the
keyboard to a high range,
the pitch does not rise all
the way
A partial consisting of
two or more samples
doesn’t sound like a
single note when you
play legato from a low
range of the keyboard to
a high range
When you play in a high
range of the keyboard,
the playback pitch is
incorrect, or noise is
heard
●
Could you be using an effect that distorts the sound?
➔
In the EFFECTS screen (Screen Guide; p. 229), check the MFX (multi-effect) settings.
●
Could the volume of a specific part be too high?
➔
In the MIXER (INSTRUMENTS PART) screen (Screen Guide; p. 236), decrease the Level.
●
Could the volume of a specific audio track be too high?
➔
In the MIXER (AUDIO TRACK) screen (Screen Guide; p. 235), decrease the Level.
●
Could the MASTER knob be set to an excessively high volume?
●
Does the sound distort when a large number of notes are played simultaneously?
➔
If the overall volume of the entire sampler is raised, distortion may occur when a large number
of notes are played simultaneously.
In the GLOBAL screen (Screen Guide; p. 173), lower the Sampler Output Gain.
●
Is the sound distorted even if you lower the output level settings in the mixer?
➔
It is possible that the sound was recorded in a distorted condition because the input level was
too high during recording. In this case, you’ll have to re-record the material.
●
Is the overall tuning of the entire MV-8800 incorrect?
➔
In the GLOBAL screen (Screen Guide; p. 173), check the Master Tune.
●
Is the pitch incorrect for just a specific patch?
➔
In the PATCH EDIT screen (Screen Guide; p. 118), check the Coarse and Fine settings.

➔
Check the Mute Control Track settings of each song or pattern.
☞
SONG PARAMETER screen (Screen Guide; p. 79)
PATTERN PARAMETER popup (Screen Guide; p. 99)
Could the number of simultaneous notes have exceeded 64?
➔
Try reducing the number of simultaneously played notes.
Depending on the structure of a partial, some partials may use eight samples (four stereo
samples). If you use such a partial, eight notes of polyphony are actually being used for each
note you play.
Also, sounds that have an extended release may still be using processing power even after
the release has become inaudible to the ear, and this will mean that the performance data can
differ from the actual number of notes being played.
Could you be using sounds that use a significant amount of LFO?
➔
Try using other sounds. LFO processing places a significant load on the processor, so
making extensive use of LFO will increase the overall processing load on the MV-8800, and
may also affect the timing accuracy of the notes themselves.
Could data be concentrated at the beginning of beats in the sequence data?
➔
Offset the data by one or two ticks so that the data does not occur at the identical timing.
If you step-recorded your song data, or if you realtime-recorded it from a keyboard and then
quantized it, the data will tend to be concentrated at the beginning of beats. This will cause a
large amount of data to be sent to the MV-8800 at once, and may cause processing of notes
to be delayed.

Cause
●
Is there a program change at the point where the playback becomes sluggish?
➔
Change the location of the program change data.
If a program change is inserted during a song, a certain amount of processing time is required
to switch patches, and this may cause the playback to become sluggish.
●
Is there a system exclusive message at the point where the playback becomes sluggish?
➔
Change the location of the system exclusive data.
Since a system exclusive message contains a large amount of data, it places a significant
processing load on the sequencer and sound generator module. Either change the location of
the data, or use a control change instead (if it is feasible to substitute a control change for the
system exclusive message).
●
Is there a large amount of aftertouch or other data at the point where the playback become
sluggish?
➔
Change the location of the data.
➔
Use the DATA THIN popup (Screen Guide; p. 42) to thin out unneeded data.
If there is unneeded data, delete that data.
If you are recording data from a keyboard that transmits aftertouch, it is easy to inadvertently
input large amounts of aftertouch data without realizing it. Such large amounts of data will
place an excessive processing load on the sequencer and sound generator.
Cause
●
Is the MIDI cable connected correctly?
●
Could the MIDI cable be broken?
➔
Use a different MIDI cable.
●
Does the MIDI track’s output assignment match the MIDI receive channel setting of your
MIDI device?
➔
In the TRACK PARAMETER popup (Screen Guide; p. 11), check the MIDI setting.
●
On your MIDI keyboard, could the Soft Thru setting be enabled?
➔
Disable the Soft Thru setting, and then connect your MIDI keyboard.
●
For a sample used by a patch, could you have exceeded the upper limit of the pitch at which

AKAI MPC 2000 (XL), S1000, S3000
The AKAI MPC2000, MPC2000XL, S1000 and S3000 are
products of Pro Audio Japan KK. You can load the sound data
used for these devices (.SND, .A1S, and .A3S files), enabling
previous assets to be utilized as is.
Audio Phrase
Sample of a certain length. Performances of several measures
can be used just as they are as recorded data by being played
repeatedly on sequencers.
Audio Track
Area in sequencer enabling storage of audio phrase
performances and direct recording of audio input from external
sources.
BPM
BPM stands for Beats Per Minute. Referring to the number of
beats (generally the number of quarter notes) per minute, it is an
indicator of the tempo (speed).
CD-R
Short for
reading and writing discs in the same format as that used for
CDs (CD-ROMs and music CDs). A specialized CD-R drive
allows one-time only writing of discs.
However, as long as the data has not been finalized and there is
sufficient capacity remaining on the disc, the CD-R drive can be
used for multiple additions to, and changes in the material.
Sometimes they are referred to as “Write Once CD,” “CD-Write
Once,” or something similar.
CD-RW
Short for
creation of discs that can be read using the same format as
regular CDs (CD-ROMs and Music CDs). While resembling the
CD-R system in that it uses a special CD-RW drive, these discs
can be rewritten any number of times.
Compressor
An effect that suppresses volume fluctuations. When the input
signal exceeds a specified level (threshold), the gain is reduced
as the input signal rises, thus suppressing signal overload. The
same algorithm can also be used as a limiter (an effect that
instantaneously suppresses peaks).
Of the effects in this system, only the compressor included in
guitar multi simulates a compact compressor for guitar, and
works differently from a limiter. (It suppresses signal overloads,
and also evens out the volume by raising low-level signals.)
COSM
Stands for
technology which combines multiple sound models to create new
sounds,” which was first used on the Roland’s VG-8 V-Guitar
System. For example, sounds created on the VG-8 are the result
of a variety of sound models (elements) such as the pickup, the
body of the guitar, the guitar amp, mic, and speaker etc.
Cue Sheet
Data including song sequence and detailed time information
settings recorded to audio CDs. Audio CDs are created
according to these cue sheets, which are written to the
CD-R/RW discs.

Current Song
The song currently being recorded, played back, or edited is
referred to as the current song.
Current Track
The currently selected track used as the material being worked
upon.
DIMM
Memory built into the MV-8800. The unit is shipped from the
factory with a 128 MB DIMM installed. DIMMs can be switched
(Owner’s Manual; p. 323) for up to 512 MB of memory.
Dynamics (effect)
Effects that compressor expand the range of volume changes.
These effects are used to reduce noise when recording to tape,
or to increase the dynamic range of a tape or wireless mic.
Dynamics effects provided on this system include Enhancer,
Expander, Compressor, and Limiter.
DSP
An abbreviation for
uses dedicated circuitry or software calculations to process
digitized audio or video signals in order to implement the
functionality of a mixer, filter, or effect processor. By extension,
DSP is also used to collectively refer to effect devices and effect
functionality that uses such technology.
Expander
An effect that increases (by a fixed ratio) the difference in loud
and soft volume levels, by making low-level signals softer, and
high-level signals louder.
Frame
Similar to the individual frames in a roll of movie film, the
numerous still pictures that are displayed in rapid succession to
create a moving video image are also known as “frames.” About
thirty of these frames are shown each second. When hard disk
recorders, sequencers, and other such equipment are
synchronized with video, it is generally assumed that there
should be one frame every 1/30th of a second.
IEC
The signals that are transferred via the digital output of this
device comply with the IEC60958 and IEC958 (consumer)
formats.
Limiter
An effect that works similarly to a compressor. When the input
signal rises beyond a specified level (threshold), a limiter
instantly lowers the gain to limit the output level. The degree of
compression is specified by the Ratio. In general, ratios of 1:10
or less are referred to as compression, in distinction to limiting.
MIDI Track

MTC
MTC stands for
which are transmitted and received between MIDI devices to
synchronize their operation. Unlike MIDI Clock messages, MTC
specifies an absolute time. Like SMPTE time code, MTC also
supports a variety of frame rates. If you wish to use MTC to
synchronize the operation of two devices, both devices must be
set to the same frame rate.
Patch
Patches are “sound sets.” On the MV-8800, patch sounds are
sounded at preprogrammed timing (sequencer playback), or are
played using the velocity pads.
Partial
These are the separate, individual sounds from which patches
are composed. Partials are samples (waveform data) processed
with the application of a variety of parameters, assigned note
numbers, and sounded.
Program File
Program files used with the AKAI MPC2000, MPC2000XL, S1000
and S3000 correspond to patches used with the MV-8800.
PS/2 Mouse
Mouse that can be connected to the connector used with PS/2
computers developed by IBM in the U.S. In the future, users will
be able to carry out tasks on the MV-8800 using a PS/2 mouse.
RSS
RSS stands for

produce sounds.
Sampling
The process of capturing and loading sounds using a sampler.
SCMS
SCMS stands for
function that protects the rights of copyright holders by
prohibiting recording via a digital connection for more than two
generations. When digital connections are made between digital
recorders that implement this function, SCMS data will be
recorded along with the audio data. Digital audio data which
contains this SCMS data cannot again be recorded via a digital
connection.

SMPTE time code
This is a signal format defined by the American organization
SMPTE (Society of Motion Picture and Television Engineers)
which is used to synchronize the operation of video or audio
devices. SMPTE specifies “hours:minutes:seconds:frames” to
indicate the address of each frame of a video image. For this
reason, there are a variety of frame rates.
SMT
The Sample Mix Table is collective data including levels, pan,
and tuning information for up to four audio data files (samples).
Song
This is recorded data containing information (events) in the
MV-8800’s performances along the time axis with recorded data
for instrument and effect settings. Data called “sequencer data”
is stored within these songs.
TOC
Short for Table of Contents. This is the region on the CD-R disc
that handles information such as song times, end times,
sequence, and so on. Although the songs on a disc and their
playing time can be displayed when an audio CD is placed in a
CD player, this is because they can be read automatically from
the TOC. The TOC is recorded differently than music data, with
its main characteristic being disc access, such as the ability to
go to the start of any song instantly.
USB
Universal Serial Bus is a serial interface specification. “USB
mass storage class” is supported on the MV-8800, so it can be
recognized by the connected computer as an externally
connected hard disk.
Velocity
ne of the sound expression parameters, velocity is used to
express the relative strength of the sound. With the MV-8800,
the value of this parameter changes according to the force used
in tapping the velocity pads or in playing the keys of an externally
connected keyboard.
VGA
VGA stands for Video Graphics Array. Although this refers to the
640 x 480 dot graphics system capable of showing 16 colors
developed by IBM in the U.S., a VGA-compatible mode
permitting display of many colors at high resolution has been
developed by other companies. Presently, VGA has come to
mean only an indication of the resolution rather than referring to
the graphics system.

MFX (Multi-effects)
01 Isolator & Filter
ese are the individual effects from which the
delay/chorus, and reverb effects are composed.
,
Isolator (3 Band Isolator)
This effect separates the input sound into three frequency
bands, High, Mid, and Low, and cuts or extracts them.
Low Level, Mid Level, High Level
Value: -60 dB–4 dB
These cut (or increase) each frequency band. At -60 dB,
the sound becomes inaudible. 0 dB is equivalent to the
input level of the sound.
AntiPhase Low MixSw, AntiPhase Mid MixSw
Value: Off, On
This turns the Anti-Phase function on and off for the low
and mid frequency ranges. When turned on, the
counter-channel of stereo sound is inverted and added to
the signal.
AntiPhase Low Level, AntiPhase Mid Level
Value: 0–100
This sets the Anti-Phase level for the low and mid
frequency ranges.The level setting allows you to achieve
the effect of extracting only a particular part. (This is
effective only for stereo source.)
Filter
These filters allow you to modify the frequency response of
the input sound widely and give sound a style.
Type
Sets the type of filter used.
Value

•
In this algorithm, the functions of the machines that make
up the basics for remix artists and pro DJs have been
minutely analyzed and reproduced. Whereas with ordinary
equalizers, some sound is still audible even when the gain
is turned all the way down, the Isolator completely cuts off
the sound. By turning this on and off and changing each
level in realtime, you can get the effect of having the sound
of particular parts appear and disappear.
MV-8800 Appendices
Curve
Value: -12 dB/oct, -24 dB/oct
Sets the filter’s attenuation slope (-24 dB per one octave:
steep; -12 dB per one octave: shallow).
Freq (Cutoff Frequency)
Value: 0–100
Sets the filter’s cutoff frequency. Set this closer to zero,
the cutoff frequency becomes lower; set closer to 100,
the cutoff frequency becomes higher.
Freq.
BPF BEF
Freq.
Effect Block
Gain
Value: 0–24 dB
This compensates for the volume dropped in the cut
frequency range with some filters. The level of
compensation increases as the value is increased, and
raise the volume.
Resonance
Value: 0–100
Sets the filter’s resonance level. Raising the setting
increases resonance near the cutoff frequency, giving
the sound a special characteristic.
•
If the resonance value is raised too much, loud strange
sound (known as oscillation) begins to appear. Take
care not to allow this sound to damage your ears or
your playback equipments.
Boost (Low Booster)
This emphasizes the bottom to create a heavy bass sound.
Boost Level
Value: 0–100
Increasing this value gives you a heavier low end.
(Depending on the Isolator and filter settings this effect
may be hard to distinguish.)

02 Center Canceler
Center (Center Canceler)
This cuts sounds in the center of the stereo field (such as
vocals).
Position (Cancel Position)
Value: -50–50
This is for finer adjustment of the cut position. Adjust this
so that the sound is cut fully.
Range
These set the upper and lower limits of the frequency
range to be cut. When “Thru” is selected, the frequencies
to be cut are not limited.
Value

EQ (3 Band EQ)
This equalizer works in three frequency ranges: Low,
Midrange, and High. You can set the frequencies and boost
or cut the level.
Gain
Sets the gain (boost or cut) of the equalizer.
Parameter
Low Gain
Mid Gain
High Gain
Freq
Sets the reference for the frequency range to be boost or
cut. With the peaking-type equalizer, this means the
center frequency; with the shelving-type equalizer, this
becomes the cutoff frequency.
Value
-12–12 dB
•
Although you can get a similar effect by using the
Anti-Phase function in Algorithm 01 Isolator & Filter (p. 16),
this algorithm differs in that you can specify the upper and
lower frequency limits of the effect. This is especially
effective when cutting vocals, for example.
•
This has no effect if the input sound is monaural.
Additionally, even in stereo, the result of cutting may
differ depending on the particular recording.
Parameter

Mid Freq 200–8000 Hz
High Freq 1.4–20.0 kHz
Value

03 St. Dynamics Processor
Comp (Comp/Limiter)
This effect is able to use as a compressor, which controls
inconsistencies in sound levels by suppressing high sound
levels while lifting weaker signals, or as a limiter that prevents
the signal from reaching exceedingly high levels.
Threshold
Value: -60–0 dB
Sets the volume level at which the compression begins.
Ratio
Value: 1:1.5, 1:2, 1:4, 1:100
Sets the “source sound:output sound” compression ratio.
Attack
Value: 0–100
Sets the time after the sound volume is crossed the
threshold level until compression begins.
Release
Value: 0–100
Sets the time for compression to stop after the sound
falls back under the threshold level.
Enhan (Enhancer)
This effect regulates the high-end overtones, clarifying the
sound and the sound contour.
Sens
Value: 0–100
Sets the degree to which the Enhancer is applied.
Freq
Value: 1.0–10.0 kHz
Sets the lower limit of the frequencies to which the
enhancement effect is added.
Mix Level
Value: 0–100
Sets the level of the overtones produced by the
Enhancer that is mixed in with the source sound.
Output Level
Value: 0–100
Sets the output volume.
Output Level
Value:-60–12 dB
Sets the output volume.
•
When used as a limiter, set the Ratio to 100:1 with a short
release time. If the volume exceeds the threshold level, the
sound is suppressed instantly detected as the excess
input.
A-20
MV-8800 Appendices
NS (Noise Suppressor)
This suppresses noise (such as background noise and hum
from mics) when no sound is being played. The noise
suppressor watches at the input level at the top of the chain
of effects, and when there is no input, turns down any output
at the end.
Threshold
Value: 0–100
Sets the volume level at which starts muting. Set the
value higher when there is a lot of noise, and if there is
less noise, decrease the value.
Effect Block
Release
Value: 0–100
Sets the time from when the muting starts until the
volume reaches 0.
•
If the threshold level is set too low, the effect is lost; when
set too high, even the sounds you want will be muted. In
addition, if the release time is set too long, the releasing
noise becomes audible; when set too short, it sounds
unnatural. Set these to suitable point for the input noise
conditions at the time.

04 Reverb & Gate
Reverb
This is a high-quality digital reverb. Imbues sound with
reverberations, making it seem as if it were being played in a
hall.
Room Size
Value: 5–40 m
Sets the size of the room. For example, the setting “10m”
gives you reverb as it would sound in a single space 10
meters wide.
Time
Value: 0.1–32 sec
Sets the reverb time in seconds.
Pre Delay
Value: 0–200 msec
Sets the delay time between the source sound and the
point at which the reverb sound is started. This indicates
distance from the source of the sound.
Diffusion
Value: 0–100
Increasing this value intensifies the sense of spatial
width. This is effective when playing back in stereo.
Density
Value: 0–100
Increasing this value makes the reverb sound denser.
For hall or garage sounds, make this thinner.
ER Level
Value: 0–100
Raising the value increases the volume of the early
reflections.
•
Early reflections: The first sounds reflected directly from the
walls and other surfaces. A sort of “patter” sound is audible
at the beginning of the reverb sound.
Low Damp Freq
Value: 50–4000 Hz
Sets the upper frequency limit of the range to be damped
by “Low Damp.” The Low Damp function damps the low
frequency band of the reverb sound quicker than other
bands, which makes for a clearer reverb effect.
Low Damp Gain
Value: -36–0 dB
Sets the degree of the Low Damp.
High Damp Freq
Value: 1–20 kHz
High Damp, by attenuating the higher frequencies first,
makes the reverb sound more natural.Sets the lower
frequency limit of the range to be dampened.
•
In the natural world, the high frequencies in reverberation
die out quicker than other bands.
High Damp Gain
Value: -36–0 dB
Sets the degree of the High Damp.
•
By combining Low Damp and High Damp, you can indicate
the qualities of the room such as surface material (or the
sound absorption properties thereof.)
High Cut Freq
Value: 0.2–20 kHz
Upper band than this frequency of the reverb sound are
gently cut to make the reverberation more stable. This
does not make time-based changings.
Direct Level
Value: 0–100
Sets the volume of the source sound.
•
To make the gate settings easy when using the gate
function to get special reverb effects, make reverb times
longer. In such instances, instead of using Low Damp or
High Damp to change the tone, do this with the High Cut
frequency settings or through equalization at an earlier
stage. To get sharp gate reverb, make the attack and
release times extremely short, and set expression time to
match the rhythm with the hold time setting. To get reverse
reverb, make the attack time plenty long, and keep the
release time short.
Effect Level
Value: 0–100
Sets the volume of the reverb sound. Lower it to get a
balance with the direct level.

Gate
This shuts off the signal. It also provides the characteristic
effect in gated reverb, which cuts off reverb sounds while
they are still being produced, ducking reverb, and other such
effects.
Gate (Gate Switch)
Value: Off, On
This turns on and off the gate function that cuts the
output of the reverb sound based on the volume of the
source sound.

Repeat Rate
Value: 0–100
Sets the tape speed. This corresponds to the delay time
in a contemporary delay effect. As the value is
increased, the interval of the delay sounds is shortened.
Intensity
Value: 0–100
Sets the repeat times of the delayed sound. This is
analogous to a contemporary delay’s feedback setting.
Raising this value increases the number of repeats.

These are the pan (left–right) settings for each of the
heads for Short, Medium, and Long delay time. This
parameter does not appear on the original RE-201.
Tape Dist.
Value: 0–5
This parameter adds the distortion characteristic of tape.
It reproduces that subtle change in tone that can only be
measured with equipments. The distortion gets more
intense as the value is increased.
Wow/Flutter Rate
Value: 0–100
The wavering becomes more rapid the higher the
Wow/Flutter rate is set.
•
The wavering of multiple pitches that appears from tape
wear and irregularities in rotation is called wow and flutter.
(This phenomenon is called “wow” when its occurs at slow
rotation speeds, and “flutter” when the tape is run quickly.)
Wow/Flutter Depth
Value: 0–100
The wavering deepens as the Wow/Flutter depth setting
is increased.

Since the RE-201 SPACE ECHO has been released in
1974, a great number of fans are still using. This algorithm
faithfully reproduces the sound of the original unit’s tape
echo section based on the real unit and the data when it
was developed. What’s more, it includes settings to
express the sway caused by the motor, distortion, and
panning for each of the three heads (something the original
lacked). Now, you can easily get this warm, Lo-Fi echo
sound, something different than the clear sound of today’s
digital delays. You can change the repeat rate (tape speed)
with the Realtime Effects knobs, and enjoy the realistic
feeling of operating this vintage device.
Bass/Treble
Value: -100–100
These are the echo sound’s bass and treble
adjustments. When set to 0, they make no change to the
sound.
