1. Introduction

Thank you for purchasing the Korg EXB-MOSS DSP
synthesizer board. In order to enjoy long and trouble­free use, please read this manual carefully and use the
EXB-MOSS correctly.

Before you use this product, you must read the
“Safety Precautions” listed in the beginning of
the Parameter Guide.

This manual explains the Bank F parameters
that are added when the EXB-MOSS is
installed. For details on the parameters other
than Bank F, refer to the TRITON’s Parameter
Guide and Basic Guide etc.

Features of the EXB-MOSS

The EXB-MOSS is an option board containing a
MOSS (Multi-Oscillator Synthesis System) tone

generator with six-voice polyphony.
The MOSS tone generator is a physical modeling tone
generator that uses Sondius-XG* technology.
When the EXB-MOSS is installed into the TRITON,
you will be able to use the 128 MOSS tone generator
programs in program bank F.

Bank F is dedicated to MOSS tone generator
programs. Bank F programs can be selected for a

timbre/track in Combination, Song, and Song Play
modes. You can also create combinations or songs
that combine bank F programs with other programs
from banks A–E or G.
Broadly speaking, a MOSS tone generator program
consists of voice, EG, LFO, effect, and control

sections.
The voice section contains an oscillator and a filter.

— The oscillator provides two oscillators (1 and 2),
which can use thirteen different oscillator algorithms,
including Standard, Ring Modulation, VPM, Reso­nance, Organ Model, and Electric Piano Model. The
oscillator also provides a sub oscillator and a noise
generator.
— The filter provides five types of filters (two filter
systems), including a Human Voice Filter that lets you
simultaneously set two center frequencies, and a Dual
Band Pass Filter that lets you simulate the body
resonances of a violin or guitar.
Five EG units and four LFO units can be used to
modulate this voice section in order to create time­varying movement of pitch, tone, and volume.
* This product was developed under license of
physical modeling tone generator patents (http://
www.sondius-xg.com) owned by Stanford University
USA and Yamaha Corporation.

2.The structure of bank F programs

Program structure

The programs of bank F have the following structure.

Oscillator

This section produces the waveform that is the basis
of the sound.
Settings are made by the “Program P1: Edit-Basic”
and “Program P2: Edit-Pitch” parameters.

— OSC 1, 2

Thirteen oscillator types (methods of sound genera­tion) are provided. Of these, you can select two
oscillator types for use together, and make basic
settings for the pitch and waveform. However for
some oscillator types, only one type can be used.
Settings are made by the parameters of “1–1: Prog
Basic,” “1–2: OSC Basic,” “1–3: OSC1,” and “1–4:
OSC2.”

— Sub oscillator

One of four basic waveforms can be selected. Its pitch
can be set in the same way as OSC1 and 2.
These settings are made by the parameters of “1–2:
OSC Basic” and “2–3: SubOSC P.Mod.”

— Noise generator

This produces white noise, which can be passed
through a multi-mode filter (low pass filter, high pass
filter, band pass filter).
Settings are made by the “1–5: Noise Generator”
parameters.

Filter

This section processes the waveform by attenuating or
boosting specific frequency ranges. Two multi-mode
filters are provided. As filter types, you can select
from low pass, high pass, band pass, band reject, or
dual band pass filters. These filters can be used to
modify the brightness of the sound. You can also
select the connection routing between the two filters
and the mixer and amp.
Settings are made by the “Program P3: Edit-Filter”
parameters.

Amp

This section modifies the volume of the sound that is
output from the filter. There are two independent
amps. The signal that is input to each will depend on
the filter connections. The amp section also provides a
special envelope generator for controlling the amp
(Amp EG).
These settings are made by the “Program P4: Edit­Amp” parameters.

Effect

This section applies effects to the signal that is output
from the amp. It has the same parameter structure as
the programs of other banks.
Settings are made by the “Program P7: Edit­Arpeggiator” and “Program P8: Edit-Insert Effect”
parameters.

Mixer

This section mixes the signals from oscillators 1 and
2, the sub oscillator, the noise generator, and the
feedback from the amp, and outputs the result to
multi-mode filters 1 and 2 (filter section).
Settings are made by the “1–6: Mixer” parameters.

EG

This section provides four general-purpose EG units.
Each EG can be used as a modulation source for
various parameters, to apply time-variant change to
the sound.
Settings are made by the “Program P6: Edit-Common
EG” parameters.

Arpeggiator

The arpeggiator can be used in the same way as for
the programs of other banks. Settings are made by the
“Program P7: Edit-Arpeggiator” parameters.

Program Basic

Here you can make settings for functions such as
Scale, Key Assign, and Controllers (joystick, ribbon
controller etc.). Settings are made by the “1–1: Prog
Basic” and “1–7: Controller Setup” parameters.

Resonance

This oscillator uses filter resonance, and is an
especially effective way to produce mallet sounds and
pad sounds. (☞p.20 of this manual)

Ring Modulation
Cross Modulation
Sync Modulation

These are special oscillators for generating the sounds
which could be produced on an analog synthesizer by
modulating one oscillator with another. These allow
you to produce sounds with complex overtone
structures such as bells, metallic sounds, and gongs.
(☞p.21–23 of this manual)

Organ Model

This simulates a drawbar organ with three drawbars
(when one oscillator is used) or six drawbars (when
two oscillators are used) (☞page 23 of this manual).
Since each drawbar can use one of four types of
waveform, a wide range of tones can be produced.

Features of the oscillator

In a bank F program, you can choose from 13
oscillator types for OSC1 and 9 oscillator types for
OSC2.
In Program P1 “1–1: Program Basic” or “1–2: OSC
Basic” you can select the oscillator type for OSC1 and
OSC2, and use them together.
If a Single Size oscillator (Standard–E. Piano Model)
is selected for OSC1, you can select a Standard–E.
Piano Model for OSC2 as well. If a Double Size
oscillator (Brass Model–Bowed String Model) is
selected for OSC1, OSC2 will be unavailable.

Standard

This simulates the oscillator of an analog synthesizer.
You can use PWM (pulse width modulation) etc. to
produce the same results as on an analog synthesizer.
(☞p.14 of this manual)

Comb Filter

This oscillator creates pitched components from noise
or an impulse. In addition to producing noisy sounds,
it can also produce a wide variety of sound ranging
from synth basses to string-like sound. (☞p.17 of this
manual)

E. Piano Model (electric piano model)

This is a physical model that simulates a warm vintage
electric piano. (☞p.24 of this manual)

Brass Model

This is a physical model that simulates a brass
instrument such as a trumpet or trombone. (☞p.25 of
this manual)

Reed Model

This is a physical model that simulates a woodwind
instrument such as a sax or flute. (☞p.27 of this
manual)

Plucked String Model

This is a physical model that simulates plucked string
instrument such as guitar or bass. (☞p.29 of this
manual)

Bowed String Model

This is a physical model that simulates a bowed string.
(☞p.31 of this manual)

VPM (Variable Phase Modulation)

This oscillator uses phase modulation to generate
harmonics. A rich harmonic structure can be created
by using phase modulation between two oscillators
and the wave shaping table. (☞p.18 of this manual)

Editing a combination

You can select a bank F program for a timbre in a
combination, and use it in the combination together
with programs of banks A–E and G. Different MOSS
tone generator programs from bank F can be selected
for two or more timbres, and used multi-timbrally. In
this case, the total polyphony of the MOSS tone
generator programs will be six voices.

Insertion/master effect settings and the routing
to the individual audio outputs cannot be made
independently for multiple timbres.

If you change programs while a bank F
program is sounding, the bank F program will
stop sounding.

When playing multi-timbrally and a bank F
program is being sounded, selecting a bank F
program for the timbre number prior to that
timbre number will cause noise to be heard in
the currently-sounding bank F program.

Editing a combination

Here’s how to select programs and set the parameters
that determine how each program will sound.

(1) Select Combination P0: Play.

For details on how to enter each page, refer to p.52
“Combination mode” in the TRITON Basic Guide.

(2) Select the combination number that
you wish to edit.

(3) Select the Combination P4: MOSS
Setup tab.

Before you select a bank F program, make settings
here to specify how the MOSS tone generator will
sound.

8

(4) Set the Voice Allocation Reserve
parameter to specify the polyphony for
each timbre.

For each timbre, specify the number of voices that
will be allocated when a MOSS tone generator
program is selected. A total of six voices can be
allocated.
For example, you might allocate two voices to timbre
1 for a bass-type MOSS program, and up to four
voices to timbre 2 for an electric piano MOSS
program.

These settings have no effect on the programs
of banks A–E and G.
When the timbre bank/program is changed to
switch a timbre from a bank F program to a
bank A–E or G program, the bank A–E or G
program will sound as usual.

When the timbre bank/program is changed to
switch a timbre from a bank A–E or G
program to a bank F program, it will sound
according to the setting you make here.
Timbres for which a value of 0 is set will not
sound if a bank F program is selected.

(5) Set the MOSS BUS Select Reference.

The bank F programs will be routed to the insertion/
master effects or individual audio output according to
the settings of the timbre you select here.

The timbre 1–8 you select here does not have

to be using a bank F program.
Bank F programs can be used for two or more timbres
according to the “Voice Allocation Reserve” setting.
However, settings for insertion/master effects and
routing to individual audio outputs can not be made
independently for two or more timbres.
Timbre settings for insertion/master effects and
routing to individual audio outputs are made in the
Program P8: Routing tab. Use the following procedure
to make settings.

Example)

1. Set “MOSS BUS Select Reference” to Timbre 1.

2. In the Program P8: Routing tab, set the timbre 1
“IFX/Indiv.Out BUS Select” to L/R.
All bank F programs that you selected will be sent to
L/R (without using the insertion effects).

3. Set the timbre 1 parameters “Send 1” and “Send 2”
to 064 and 127 respectively.
The signal will be sent to MFX1 and MFX2 at the
specified levels.

4. If you wish to use an insertion effect, set “IFX/
Indiv.Out BUS Select” to IFX1–IFX5. If you wish to
output to the [AUDIO OUT INDIVIDUAL] 1–4 jacks,
select 1–4, 1/2, or 3/4.

The actual levels of send 1 and 2 for a timbre
using a bank A–E or G program is determined
by multiplying the timbre setting by the send
level of the program, but for timbres that use a
bank F program, the send level setting of the
timbre will be the actual level.

This setting has no effect for bank A–E or G
programs.

(6) Select Combination P1: Edit-Program/
Mixer.

Sequencer and Song Play

modes

Bank F programs can be selected for playback of a
song or Standard MIDI File, or for performance from
the keyboard. In the same way as in a combination,
bank F programs can be selected for two or more
tracks and used multi-timbrally. In this case, the total

polyphony of the bank F programs will be six
voices.

Insertion/master effect settings and individual
audio output routing cannot be specified

independently for each track.
Details of the settings, the operation of each param­eter, and cautions are the same as for combinations.
Refer to “Editing a combination” on p.8 of this
manual.

☞ Sequencer P4: MOSS T01–08, MOSS T09–16 tabs
☞ Song Play P1: MOSS T01–08, MOSS T09–16 tabs

(7) In “Bank/Program,” select a bank F
program.

Programs can also be selected from the “Category/Program
Select” menu or the “Bank/Program Select” menu.

(8) Use “Pan” to adjust the panpot of the
timbre.

When a bank F program is selected, the Random
setting will not be available. If Random is selected,
the sound will be placed in the center, as with C064.

(9) Use “Volume” to adjust the volume of
the timbre.

(10) Make settings for other parameters.

In the same way as for programs of other banks, set the
parameters of each timbre, and make arpeggiator settings and
insertion/master effect settings.
However when a bank F program is selected for a timbre, the
following parameters will function as explained below.
— “OSC Select” will have no effect. (Combination P2:
OSC tab)

The “Detune” range will be ±100. Even if the absolute

—
value of the parameter setting is greater than 100, the actual
detune value will be ±100 cents. (Program P2: OSC tab)
— The Key Zone / Vel Zone “Top Slope” and
“Bottom Slope” settings will have no effect. (Program
P4: Key Z, Vel Z tabs)

controller which will specify whether or not the sound
will be retriggered when a note-on occurs.

Threshold (Retrigger Control Threshold) [1…127]

Specifies the value at which EG and LFO will be
retriggered by a note-on.
The state of the controller selected by Retrigger
Control (i.e., whether the controller value is above or
below the specified Threshold value) will determine
whether or not the sound will be retriggered when a
note-on occurs.

The operation of this function will differ depending on
the “Voice Assign Mode” setting.
With a setting of Mono (Single), retriggering will
occur if the controller is above the threshold value. If
Retrigger Control is OFF, retriggering will not occur.
With a setting of Mono (Multi), retriggering will
occur if the controller is below the threshold value. If
Retrigger Control is OFF, retriggering will always
occur.

If a note-on occurs when all notes are off,
retriggering will always occur.
LFO’s whose Key Sync is turned OFF will
not be reset even if retriggering occurs.

Priority [Low, High, Last]

Specifies the priority order that will be used when the
number of keys pressed exceeds the maximum
polyphony.

Low: The lowest note will take priority
High: The highest note will take priority

Last: The last-pressed note will take priority

Hold

When this is checked, the note will continue to sound
after the key is released. However, if the EG selected
by “4–1: Amp1,” “Amp2” (normally the Amp EG is
used) has a sustain level of zero, the note will decay
naturally.

1–1d: Scale

Specifies the scale type

Type (Scale Type)

[Equal Temperament…User Octave Scale 15]

Selects the basic scale for the internal tone generator.
The user scales can be specified in Global mode “3–1:
User Scale” (☞page 127 in Parameter Guide).

Equal Temperament

The most widely used scale, consisting of equally­spaced semitone steps.

Pure Major

The major chords of the selected key will be per­fectly in tune.

Pure Minor

The minor chords of the selected key will be per­fectly in tune.

Arabic

This reproduces a quarter-tone scale of Arabic mu­sic.

Pythagorean

A scale based on ancient Greek musical theory, suit­able for playing melodies.

Werckmeister (Werkmeister III)

An equal-tempered scale used in the later Baroque
period.

Kirnberger (Kirnberger III)

A scale created in the 18th century, and used mainly
for tuning harpsichords.

Slendro

An Indonesian gamelan scale in which the octave
consists of 5 notes.
If the Key parameter is set to C, use the C, D, F, G,
and A keys. (Other keys will produce the same
pitches as equal temperament.)

Pelog

An Indonesian gamelan scale in which the octave
consists of 7 notes.
If the Key parameter is set to C, use only the white
keys. (The black keys will produce the same pitches
as equal temperament.)

Stretch

This is a tuning used on acoustic pianos.

User All Notes Scale

This is the full-range scale (C-1=G9) that you cre­ate in Global mode “3–1b: User All Notes scale”
(☞page 121 in TRITON Parameter Guide).

User Octave Scale 00–15

This is the one-octave scale that you create in Glo­bal mode “3–1a: User Octave Scale” (☞page 121
in TRITON Parameter Guide).

Key (Scale Key) [C…B]

Specify the tonic note of the selected scale. This
setting has no effect for Equal Temperament,
Stretch, or User All Note Scale .

If a scale other than equal temperament is
selected, certain combinations of this param­eter and the “Key” parameter may cause the
tuning of the base key (for example A=440
Hz) to become incorrect. If this occurs, you
can adjust the “Master Tune” (Global P0:
Basic tab).

Random [0…99]

As this value is increased, the pitch of the note will
become increasingly unpredictable. Normally you will
leave this set at zero.
Adjust this parameter when you wish to simulate
instruments whose pitch is naturally unstable, such as
tape-mechanism organs or acoustic instruments.

Standard

1–3a

1–3b

1–3c

This oscillator produces the waveforms used by an
analog synthesizer (sawtooth wave, pulse wave,
triangle wave) and sine wave. Sawtooth wave, pulse
wave and triangle wave waveforms can be modified
using waveform modulation. You can specify either
sawtooth wave or pulse wave as the main waveform,
and mix triangle wave or sine wave with this for
output. The level of these three waveforms can be
adjusted independently.
In addition, wave shaping can be applied to the output
of this oscillator.

Waveform modulation

Pulse width modulation (PWM) on an analog synthe­sizer produces time-varying change in the pulse width
of a pulse wave. The waveform modulation provided
by the EXB-MOSS option is an extension of this,
which varies not only the pulse width but also the
waveform of a sawtooth wave or triangle wave.
Waveform modulation will affect the various wave­forms as follows.

1–2c: Sub OSC

Make basic settings for the sub oscillator.
Parameters other than Waveform are the same as for
oscillator 1.

Waveform [Saw…Sine]

Select the waveform of the sub oscillator.

14

Sawtooth wave

-99 -33 0 33 66 99

Waveform modulation will modify a sawtooth
waveform as shown below, creating time-variant
change in the sound.

When modulation is 0, the basic sawtooth waveform
will be produced, and when it is 99, a sawtooth wave
of double the frequency will be produced. If the
modulation value is a negative number, a different
effect will result than with positive settings.

Pulse wave

-98 -33 0 33 66 98

Waveform (pulse width) modulation will modify a
pulse waveform as shown below, creating time-variant
change in the sound. When modulation is 0, a square
wave will be produced, and when it is 99, the pulse
width will be 0, meaning that there will be no sound.
If the modulation value is a negative number, the
results will be inverted.

Triangle wave

Sine Level [0…99]

Specifies the output level of the sine waveform. It will
be output mixed with the main waveform.

Phase Shift (Triangle & Sine Phase Shift)

[–99…+99]

waveform and the triangle and sine waveforms. (The
triangle and sine waveforms will always be in phase
with each other.)

1–3b: Waveform (Waveform Modulation)

Waveform

[–99…+99]

Specifies the waveform. For the way in which this
value will affect the waveform, refer to the diagrams
shown on the previous page for sawtooth wave, pulse
wave, and triangle wave.

-99 -25 0 25 50 75 99

Waveform modulation will modify a ramp wave as
shown below, creating time-variant change in the
sound. When modulation is 0, a triangle wave will
result, and as the modulation value increases, the
waveform will become a ramp wave (a waveform in
which the slope is broken in two). At a modulation
value of 50, a trapezoidal wave will result, and at a
value of 99 the waveform will once again be a triangle
wave. If the modulation value is a negative number,
the results will be inverted.Compared to sawtooth or
pulse waves, this waveform produces a strong
fundamental with fewer overtones, making it particu­larly suitable for bass sounds etc.

(sawtooth wave) or Pulse (pulse wave).

Level [0…99]

main waveform. As the pitch rises, this effect will
become stronger, and in the low range there will be
little effect. Lower settings of this parameter will
produce a more mellow sound, and in the vicinity of 0
the volume will also decrease.

Triangle Level [0…99]

Specifies the output level of the triangle waveform. It
will be output mixed with the main waveform.
