Noise Gate; Adr-Noise Gate; Pitch Change Programs - Yamaha SPX1000 Operation Manual

PARAMETERS ACCESSED BY THE INT PARAM
KEY
High-pass Filter Frequency (HPF FRQ): THRU, 32 Hz
– 1.0 kHz
Permits rolling off the low-frequency content of the reverb
signal above the set frequency. The HPF is OFF when set to
THRU.
Low-pass Filter Frequency (LPF FRQ): 1 – 16 kHz,
THRU
Permits rolling off the high-frequency content of the reverb
signal above the set frequency. The LPF is OFF when set to
THRU.

NOISE GATE

19. 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.
PARAMETERS ACCESSED BY THE PARAM KEY
Trigger Level (TRG. LEVEL): 0 – 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 0% even the tiniest input
signal will trigger the gate.
Trigger Delay (TRG. DLY): -100 – +100 milliseconds
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): 3 – 24000 milliseconds
This parameter makes it impossible to re-trigger the gate
function until the programmed time has elapsed.
Attack Time (ATTACK): 3 – 24000 milliseconds
Determines how long it takes for the gate to open fully from
the time it begins to open.
Decay Time (DECAY): 3 – 24000 milliseconds
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 – 24000 milliseconds
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): 3 – 24000 milliseconds
Determines how long it takes for the gate to close fully after
the HOLD TIME has ended.
Analog Trigger Level (A. TRG LVL): 0 – 100%
When an analog signal applied to the rear-panel TRIGGER 2
ANALOG jack is used to trigger the gate, this parameter
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. When this function is used the
TRG. LEVEL parameter should be set to the highest value
(100%) so that only signals applied to the TRIGGER 2
ANALOG jack will activate the gate.
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.
NOTE:
This effect can also be triggered by the front-panel
TRIGGER key or a footswitch plugged into the rear-panel
TRIGGER 1 SW jack.
