Obviously,
if

down

the

is
set to

EGS(off,

EG
Shift sets the
range of
the envelope.
When
"oft^'
is
selected, the
EG
will
change
the operator output
level
over a range of
to
-96dB
(the
full
range).
However,
when
12,
24
or 48
is
selected,
the
EG
range
is
"compressed"
to the specified range.
For
example,
if
EG
Shift
is
24, the
EG
will
change
the
operator output
level
over
a range of
to
-
24dB,
and
the operator output
level will
be
at
"24dB
even before

EG Copy
When
trying to imitate an acoustic instrument sound,
it is
usually a
good
idea
to
first
program
the carrier
envelope
(volume envelope) and copy
it
to the
modulating
operators.
(You
will
probably need
to
make
fine
adjustments
later
by
ear.)
Usually, as the
volume
oi'
a
sound
increases
(or de-
creases), the
tone
also gets brighter
(or softer),
so the
mo-
dulator envelopes
will
resemble
the carrier envelopes.
To
copy an envelope

press
and
hold
the
STORE
switch.
Move
the
blinking cursor
and
use

switches
to select the
source and
destination operators.
The
envelope
(AR, DIR, DIL, D2R,
RR)
and
scaling
parameters
(LS,
RS)
will
be copied.

Operator Out
Level (0—99)
This
sets
the
output
level
of each operator.
The
output
level
of
a carrier
will affect the
volume, and
the
output
level
of
a
modulator
will affect the tone.
If
you
set
output
levels
of over
90,
the output
will
be
distorted
slightly.
Sometimes
this
may
be
desirable to create a thicker
sound.
What
the
human
ear
interprets as
loudness
is
closely related to
timbral complexity
(tone),
and
raising
the
level
of
a
modulator
will
often increase the "loudness"
as
well.

Rate
Scaling (0-3)
On
an acoustic instrument, high notes usually have
a
faster
attack
and
decay than low
notes.
