By installing the separately sold EXB-MOSS option, you can
add a MOSS tone generator to this instrument, and add
MOSS program bank F.
This section explains only the parameters of the MOSS tone
generator.
For details on other parameters, refer to the Parameter
Guide, Basic Guide, and GE Guide of this instrument.
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 this instrument, you will be able to use
128 MOSS tone generator programs in program bank F.
Bank F can be used as a dedicated bank for MOSS tone gen-
erator programs, and bank F programs can be selected for
timbres/tracks in Combination, Song, Song Play mode. You
can also create combinations or tracks that use these pro-
grams in conjunction with the programs of banks A–E and
G, g(0)–g(9), g(d).
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.

erator patents (http://www.sondius-xg.com) owned by

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.
