/ 12. SYMPHONIC / This effect is produced in the same way as the flange effect, but has a "bigger," more sweeping sound. Modulation Frequency (MOD. FRO): 0.1 Hz - 20.0 Hz Sets the speed of the effect variation. Modulation Depth (MOD. DEPTH): 0% - 100% Sets the depth of the effect. / 14. ADR-NOISE GATE / This program uses a "gate" to pass or shut off the input signal in a number of ways. It can be used to pass just a short segment of a longer input signal, or it can be set up to pass only signals that exceed a specified level. In the latter case this program functions as a "noise gate." It is also possible to create reverse gate type effects in which the gain increases gradually after the effect is triggered. (LEVEL) 100% DECAY LVL = 100% DECAY LVL DECAY ATTACK HOLD RELEASE (TIME) Trigger Level (TRG. LEVEL): 1 - 100 Determines the level of the input signal required to trigger "opening" of the gate. At 100% only very high-level input signals will trigger the gate, while at 1% even the tiniest input signal will trigger the gate. Trigger Delay (TRG. DLY): -100 - + 100 ms Produces a delay between the time at which the gate is triggered and that at which it actually opens. If a minus value is programmed, the input signal is delayed so that, effectively, the gate opens before the signal appears. Trigger Mask (TRG. MSK): 5 - 32,000 ms This parameter makes it impossible to re-trigger the gate function until the programmed time has elapsed. Attack Time (ATTACK): 5 - 32,000 ms Determines how long it takes for the gate to open fully from the time it begins to open. Decay Time (DECAY): 5 - 32,000 ms Determines the length of time it takes for the gate envelope to fall to DECAY LEVEL after it is fully open. Decay Level (DECAY LVL): 0 - 100% Determines the level at which the gate remains open for the HOLD TIME. The lower the value, the lower the HOLD gate level. Hold Time (HOLD): 1 - 30,000 ms Determines how long the gate stays open, allowing the signal to pass at the DECAY LEVEL, after the first decay and prior to beginning of the RELEASE TIME. Release Time (RELEASE): 5 - 32,000 ms Determines how long it takes for the gate to close fully after the HOLD TIME has ended. MIDI Trigger (MIDI TRG.): OFF, ON When this parameter is turned ON, a KEY ON EVENT message from an external MIDI keyboard can be used to trigger the gate. A KEY ON EVENT message is transmitted whenever a note on a MIDI keyboard is played. 15

SYMPHONIC
/
This
effect
is
produced
in
the
same
way
as
the
flange
effect,
but
has
a
"bigger,"
more
sweeping
sound.
Modulation
Frequency
(MOD.
FRO):
0.1
Hz
-
20.0
Hz
Sets
the
speed
of
the
effect
variation.
Modulation
Depth
(MOD.
DEPTH):
0%
-
100%
Sets
the
depth
of
the
effect.
/
14.
ADR-NOISE
GATE
/
This
program
uses
a
"gate"
to
pass
or
shut
off
the
in-
put
signal
in
a
number
of
ways.
It
can
be
used
to
pass
just
a
short
segment
of
a
longer
input
signal,
or
it
can
be
set
up
to
pass
only
signals
that
exceed
a
specified
level.
In
the
latter
case
this
program
functions
as
a
"noise
gate."
It
is
also
possible
to
create
reverse
gate
type
effects
in
which
the
gain
increases
gradually
after
the
effect
is
triggered.

Trigger
Level
(TRG.
LEVEL):
1
-
100
Determines
the
level
of
the
input
signal
required
to
trigger
"opening"
of
the
gate.
At
100%
only
very
high-level
input
signals
will
trigger
the
gate,
while
at
1%
even
the
tiniest
input
signal
will
trigger
the
gate.
Trigger
Delay
(TRG.
DLY):
-100
-
+
100
ms
Produces
a
delay
between
the
time
at
which
the
gate
is
triggered
and
that
at
which
it
actually
opens.
If
a
minus
value
is
programmed,
the
input
signal
is
delayed
so
that,
effectively,
the
gate
opens
before
the
signal
appears.
Trigger
Mask
(TRG.
MSK):
5
-
32,000
ms
This
parameter
makes
it
impossible
to
re
-trigger
the
gate
function
until
the
programmed
time
has
elapsed.
Attack
Time
(ATTACK):
5
-
32,000
ms
Determines
how
long
it
takes
for
the
gate
to
open
fully
from
the
time
it
begins
to
open.
Decay
Time
(DECAY):
5
-
32,000
ms
Determines
the
length
of
time
it
takes
for
the
gate
envelope
to
fall
to
DECAY
LEVEL
after
it
is
fully
open.
Decay
Level
(DECAY
LVL):
0
-
100%
Determines
the
level
at
which
the
gate
remains
open
for
the
HOLD
TIME.
The
lower
the
value,
the
lower
the
HOLD
gate
level.
Hold
Time
(HOLD):
1
-
30,000
ms
Determines
how
long
the
gate
stays
open,
allowing
the
signal
to
pass
at
the
DECAY
LEVEL,
after
the
first
decay
and
prior
to
beginning
of
the
RELEASE
TIME.
Release
Time
(RELEASE):
5
-
32,000
ms
Determines
how
long
it
takes
for
the
gate
to
close
fully
after
the
HOLD
TIME
has
ended.
MIDI
Trigger
(MIDI
TRG.):
OFF,
ON
When
this
parameter
is
turned
ON,
a
KEY
ON
EVENT
message
from
an
external
MIDI
keyboard
can
be
us-
ed
to
trigger
the
gate.
A
KEY
ON

message
is
transmitted
whenever
a

on
a
MIDI
keyboard
is
played.
