DCO corresponds
to
the
VCO
of
an analog synthesizer,
and
is comprised
of WAVE
FORM
for
selection
of
the
basic
wavefornn
and ENV
(pitch
envelope)
for control of the
pitch over time
for
a
pressed
key.
The
dual
system
line
pro-
vides an
independent
DCO 1
and DCO 2 which
can
be used as
desired.
•WAVE FORM
Determines the
basic
waveform
of
a
tone.
Independent
settings can be
made using the DCO 1 and
DCO 2
keys.
As can be seen in Fig.
8,
there
are eight
types of
basic
waveforms: from
SAW-TOOTH
to RESONANCE III.
Any
one of these eight
waveforms can
be
combined
as
shown
in Fig.
9 to produce
a
total of
33
waveforms
suitable
for virtually
any application.

Fig.
10 indicates
that
only
the
saw-tooth
pattern
is
selected.
(Only
the
FIRST
waveform
is
applied
when
SECOND
=
is
displayed.)
At
this
time,
the
VALUE
keys
can
be
used
to
set
FIRST
(the
current
position
of
the
cursor)
to
a value
from
1
through
8
to
select
the
required
waveform.
Then
the
CURSOR
keys
can
be
used
to move
the
cursor
under
the
value
of
SECOND
and
another
waveform
can
be
set
using
the
VALUE
keys
(see Fig.
11).
This
procedure
is
used
to
select
one
of
the
33
combi-
nations
of
basic
waveforms.

When the

ENVELOPE
(PITCH
ENVELOPE)
DCO
controls
changes
in pitch
over time.
Independent
envelopes
can be set using the
DCO
1
and
DCO
2 ENV
keys.
The PITCH envelope
sets the change
in
pitch
over
time
up
to
8
levels
for
pressed
keys
in
accordance
with
the
RATE
and
LEVEL.
Now let*s set up an
actual
4-step
envelope
as
shown
in Fig. 12.
