NUMERICIA»VLJUES
RATE
The
RATE
indicates
the slope
(interior
angle
in
relation to
horizontal) of
each
step
in
the enve-
lope.
R =
99
indicates nearly
90*^ while
R =
indicates nearly 0°.
Since the value
used
is
an
absolute
value,
the slope
increases
and
decreases
in
direct
proportion with the value
of
R,
regardless
of
whether
the pattern
shows
a
rise
or
fall.
This
means
that
a
steep incline results
in
a
quick
level
change
while a gentle
incline results
in
a slow
level
change.

LEVEL
The
LEVEL
indicates
up
to
what
point
each
step
rises or
falls
(destination level),
and
the
range
is
from
00
through
99.
For the
DCO
envelope,
LEVEL means
the pitch height,
and a
value
of
00
is
the pitch of
a pressed
key.
For the
DCW
enve-
lope,
L
=
99
results
in
a
basic
waveform. For the
DCA
envelope,
LEVEL means
the
volume.

DCW
corresponds
to
the
VCF
of
an analog
synthesizer,
and
is
comprised
of
KEY
FOLLOW
for control of the
wave-
form corresponding
to
the
keyboard
range,
and
ENV
(wave
envelope).
The
dual system
line
provides an indepen-
dent
DCO

DCO

which can be used
as
desired.

This parameter applies
a

in
accordance
with the
pitch of the

played.

keys
are
used
to
independently
set
each key

Key
follow
can be
set to levels
ranging from through
9.
The
higher the note played, the
closer,
the
waveform
comes
to
being a
sine (cosine)
wave. (See

The
VALUE
keys
in
the
Data Entry Section are used
to
set
the
RANGE
value
within
a range
of
through
9.
The
greater the
RANGE
value the greater the
wave-
form
level
variance (timbre
change
rate)
in
the upper
registers.
A
setting of
9 represents the
maximum
variance.
