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.

LFO

This section provides four LFO units. Each LFO can be used as a modulation source for various parameters, to apply cyclic change to the sound.

Settings are made by the “Program P5: Edit-Common LFO” parameters.

OSC	Mixer			FX	Master
Oscillator 1		Filter	AMP
					Effect
Oscillator 2		Filter 1	Amp1
		LPF/HPF/BPF/BRF/2BPF		Insert	Master	L/Mono
Sub Oscillator	Mixer		Pan	Effect
		Filter 2			EQ	R
			Amp2
Noise Generator		LPF/HPF/BPF/BRF/2BPF
						INDIVIDUAL
			Feedback			1, 2, 3, 4

& other controllers

LFO1 LFO2 LFO3 LFO4

5

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.

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)

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)

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.

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)

* Same as the preloaded data of the TRITON.

When you load MOSS.PCG

Programs, combinations, drum kits, arpeggio patterns, and global settings will be written into the TRITON’s internal memory.

When you load MOSS.PCG, all the current contents of internal memory will be erased and overwritten.

When you load MOSS.SNG

Demo songs that use the bank F programs etc. of MOSS.PCG will be loaded. These songs can be played in Sequencer mode.

When you select and load MOSS.SNG, all the current contents of sequencer memory will be erased and overwritten.

Selecting a program/

combination

In “Program P0: Play,” you can select a bank F program 000–127 in the same way as for banks A–E. You can also select programs from the “Category/ Program Select” menu or the “Bank/Program Select” menu.

Combinations can be selected in “Combination P0: Play,” and also from the “Category/Combination Select” menu or the “Bank/Combination Select” menu.

For a list of the programs/combinations in the included floppy disk, refer to “Voice Name List” on p.49 of this manual.

Editing a program

If a bank F MOSS tone generator program is selected in “Program P0: Play,” you can use P1–P9 to edit the program parameters. For details on the program parameters, refer to the “Parameters” section that begins on p.11 of this manual.

The performance editor parameter “Pitch Stretch” of “Program P0: Play” cannot be used for bank F programs.

7

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.

(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.

8

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)

9

Control change transmission/

reception for the EXB-MOSS

In the same way as bank A–E or G programs, bank F programs can receive MIDI control changes CC#70– 79, and can be operated by the front panel realtime control knobs 1–4 in A-mode. In B-mode, CC#70–79 can be assigned as knob functions, and used to control the program sound. These settings can be saved by writing them in Program mode.

OSC 2 (Oscillator 2 Type)

[Standard…E. Piano Model]

Selects the oscillator type for oscillator 2. Refer to OSC 1.

1–1b: Unison

Here, you can make settings for unison mode.

Unison [OFF, 2voices, 3voices, 6voices]

Specifies the number of notes which will be sounded in unison. With a setting of OFF, unison will not be used.

The maximum polyphony will be three notes with a setting of 2voices, two notes for a setting of 3voices, and one note for a setting of 6voices.

Mode [Fixed, Dynamic]

Specifies how the number of voices specified by the “Unison” setting will be allocated.

With a setting of Fixed, the number of voices specified by the “Unison” setting will always sound. With a setting of Dynamic, the number of voices will be determined by the current note-playing situation.

Detune

[0…99]

Detunes the notes that are sounded simultaneously by the Unison function.

1–1c: Voice Assign Mode

Here, you can specify how notes will sound when keys are pressed.

Poly, Mono (Single, Multi)

Selects whether the sound will be played monophonically or polyphonically.

Poly: Polyphonic playing

Mono (Single): Single-triggered monophonic playing Mono (Multi): Multi-triggered monophonic playing.

When Poly is selected, the Retrigger Control and Threshold parameters will be unavailable.

Retrigger (Retrigger Contol) [Off…MIDI:CC#83]

“Retrigger” refers to the action of resetting the EG and LFO at the time of note-on (the EG will return to its start level, and the LFO will return to the beginning of the cycle of its waveform). Here you can select the 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.

12

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.

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

Stretch,orUserAllNoteScale	.

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.

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.

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.

14

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

-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.
