Yamaha REX50 - Manual (Page 16)

This effect is produced in the same way as the flange
effect, but has a "bigger," more sweeping sound.
Modulation Frequency (MOD. FRQ): 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-IMOISE GATEV
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.
/ 12. SYMPHONIC /
100%
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 EVENT message
is transmitted whenever a note on a MIDI keyboard
is played.
(TIME)
Trigger Level (TRG. LEVEL): 1 - 1 0 0
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. PLY): -100 — -i-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.
