Exb-Moss Option; Features Of The Exb-Moss; The Structure Of A Moss Tone Generator Program - Korg Triton-Rack Parameter Manual

EXB-MOSS option

By installing the separately sold EXB-MOSS option, you can
add a MOSS tone generator to the TRITON-Rack, and add
MOSS program bank INT-F.
This section explains only the parameters of the MOSS tone
generator.
For details on other parameters, refer to the Parameter
Guide and Basic Guide of the TRITON-Rack.
Before you use the EXB-MOSS, be sure to read the sec-
tion "Safety precautions" included at the beginning of
this manual.

Features of the EXB-MOSS

The EXB-MOSS is a MOSS (Multi-Oscillator Synthesis Sys-
tem) option board with six-voice polyphony.
The MOSS tone generator is a physical modeling tone gener-
ator that uses Sondius-XG* technology. When the EXB-
MOSS is installed in the TRITON-Rack, you will be able to
use 128 MOSS tone generator programs in program bank
INT-F (I-F).
Bank INT-F (I-F) can be used as a dedicated bank for MOSS
tone generator programs, and bank I-F programs can be
selected for timbres/tracks in Multi mode. You can also cre-
ate combinations or tracks that use these programs in con-
junction with the programs of banks I-A–I-E and G, g(0)–
g(9), g(d), and E-A–E-H.
Broadly speaking, a MOSS tone generator program consists
of voice, EG, LFO, effect, and controller sections.
The voice consists of an oscillator and a filter.
• The oscillator section provides two oscillators (oscillator
1 and 2, for which you can select from thirteen different
oscillator algorithms, including standard, ring
modulation, VPM, resonance, organ model, and electric
piano model), plus a sub-oscillator and a noise
generator.
• The filter section lets you choose from five types of filter
(two filter units), including a human voice that lets you
simultaneously specify two center frequency points, and
a dual band-pass filter that lets you simulate the body
resonances of a violin or guitar.
By using five EG units and four LFO units to modulate this
voice section you can apply a rich variety of pitch, tonal, and
volume changes to each voice.

The structure of a MOSS tone genera-
tor program
A MOSS tone generator program is structured as follows.
OSC (oscillator)
This section produces the waveform that is the basis of the
sound.
These parameters are set in PROG 2.1: Ed-Basic, PROG 2.3:
Ed-OSC, and PROG 3.1: Ed-Pitch.
• Oscillator 1/2
The EXB-MOSS provides thirteen methods of generating
sound (13 oscillator types). You can combine two of these
oscillator types, and specify the basic pitch and how oscilla-
tion will occur. However for some oscillator types, only one
may be used at a time.
These parameters are set in PROG 2.1: Ed-Basic, Prog Basic
page and OSC Basic page, and in PROG 2.3: Ed-OSC.
• Sub Oscillator
You can select one of four basic waveforms.
Pitch-related settings can be made in the same way as for
Oscillator 1/2.
These parameters are set in PROG 2.1: Ed-Basic, Prog Basic
and OSC Basic pages.
• Noise Generator
This generates white noise. The noise can be sent through a
multi-mode filter (low pass filter, high pass filter, band pass
filter).
These parameters are set in PROG 2.1: Ed-Basic, Noise Gen.
page.
Mixer
Here, the signals from Oscillator 1/2, Sub Oscillator, Noise
Generator, and the feedback from the AMP are mixed, and
output to multi-mode filters 1/2 (Filter 1/2).
These parameters are set in PROG 2.1: Ed-Basic, OSC Mixer1
and OSC Mixer2 pages.
Filter
This section contains two multi-mode filters. As the filter
type, you can select low pass filter, high pass filter, band
pass filter, band reject filter, or dual band pass filter. You can
also select the routing between the two filters and the mixer
and amp.
These parameters are set in PROG 4.1: Ed-Filter.
