HARMONICS (16' 8 ' 4 ' 2 )
The Harmonics parameters turn any combination of
individual squarewave harmonics on and off, regard­
less of the Waveform Parameter Value. This allows a
wide variety of different waveforms to be created. For
example, you could add together just the 16' and 4 '
harmonics, at either the same level (Square Wave­
form), or with the 16' harmonic 3 times louder than
the 4 ' harmonic (Sawtooth Waveform).
• When a Square Waveform is selected (Value of
and any single ONE of the Harmonics parameters
is ON, a regular square wave is produced at the
selected pitch range.
* Combining TWO OR MORE of the Harmonics with
the Square Waveform selected produces octave
doubling "effects."
• When the Waveform Value is
16' - 2 ' Harmonics are turned ON, the DCO wave­
form will be a close approximation of a sawtooth
waveform.

* With all Harmonics turned ON, the basic pitch
range will be selected by the Octave parameter
( ;! ). However, several types of modified saw­
tooth waveforms are available by turning OFF 1
or 2 of the higher Harmonics, and higher-pitched
sawtooths are available by turning OFF the 16'
or 16' & 8 ' Harmonics.

LEVEL
The maximum level of DCO 1 can be adjusted over
a range of 0 (off) to f ; i
for adjusting the overall volume to match other pro­
grams, and for balancing DCO 1 and DCO 2 in Dou­
ble Mode.

3.4.2 MODE

The DCO MODE parameter determines the basic architec­
ture of the EX-800:
WHOLE Mode 8 individual voices with 1 DCO and 1 DEG
per voice. (LED Dot OFF)
DOUBLE Mode 4 individual voices with 2 DCOs and 2
DEGs per voice. (LED Dot ON)
The LED Dot next to the Key Assign Mode Display always
shows whether the currently selected Program is in WHOLE
Mode or DOUBLE Mode:

In WHOLE Mode, all 8 DCOs are controlled by the DCO 1
!':
Parameters ( i i - ), and the 8 related DEGs are all con­
trolled by the DEG 1 Parameters ( S i - SS )•
Trying to access any DCO 2 or DEG 2 Parameters ( ,? i - 3,?
and 5 i - S5 ) will produce a blank readout in the Value dis­
play, to show that they are not currently being used. However,
the previous values of these parameters are still saved in
memory, and will be available again when DOUBLE Mode
is selected.
In DOUBLE Mode, 4 DCOs and DEGs are controlled by the
DCO 1 and DEG 1 parameters, and the other 4 DCOs and
DEGs are controlled by the DCO 2 and DEG 2 parameters.
Exceptionally dynamic and realistic sounds result from us­
ing a SEPARATELY programmed 6-stage Digital Envelope
Generator to control EACH of the two DCOs that are " layered"
together for each note.)
