Rev 5 Echo Room; Early Reflection Programs; Gate Reverb; Reverse Gate - Yamaha SPX1000 Operation Manual

Width fine: -100 – +100
This sets the value specified with WIDTH as the reference
value (0) and is the parameter for fine adjustment.
Height Fine: -100 – +100
This sets the value specified with HEIGHT as the reference
value (0) and is the parameter for further fine adjustment.
Depth Fine: -100 – +100
This sets the value specified with DEPTH as the reference
value (0) and is the parameter for further fine adjustment.
Wall Vary Fine (W. VARY FINE): -100 – +100
This sets each of the value specified with WIDTH, HEIGHT,
DEPTH, and WALL VARY as the reference value (0) and is
the parameter for further fine adjustment.
W. Decay: RT x 0.1 – 1.0
Among the REV components, this sets the reverberation time
of the REV components specified with WIDTH to a multiplier
value corresponding to the REV TIME. It simulates the
acoustic properties of the side walls.
H. Decay: RT x 0.1 – 1.0
D. Decay: RT x 0.1 – 1.0
In the same way as for W. Decay, this sets a multiplier value
corresponding to REV TIME for reverberation time felt in
relation to the HEIGHT (vertical direction) in the height
direction and that felt for the DEPTH in the front-to-back
direction. It also simulates the acoustic properties of the walls
in the vertical and front-to-back disrections.
PARAMETERS ACCESSED BY THE INT PARAM
KEY
Early Reflection/Reverb Balance (ER/REV BAL.): 0 –
100%
This parameter determines the level balance between the
early-reflection portion and final reverberation portion of the
reverb sound. At 100% only the early-reflection sound will be
produced. At 0% only the final reverberation sound will be
produced. A setting of about 50% produces both the early-
reflection and final reverberation sounds at equal level.
Reverb Delay (REV DLY): 0.1 – 300.0 milliseconds
Sets the delay between the beginning of the early reflections
– the initial group of sparse reflections that precede the dense
reverb sound – and the beginning of the reverb sound.
Density (DENSITY): 0 – 4
This parameter determines the density of the reverb
reflections (i.e. the average amount of time between
reflections). A setting of 1 produces minimum reverb density
for a more spacious sound, while a setting of 4 produces the
most dense, "tightest" reverberation.
Trigger Level (TRG. LEVEL): 0 – 100%
Determines the level of the input signal required to trigger
"opening" of the reverb program 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 milliseconds
Produces a delay between the time at which the gate is
triggered and that at which it actually opens.
Hold Time (HOLD): 1 – 24,000 milliseconds
Determines how long the gate stays open, allowing the signal
to pass.
Release Time (RELEASE): 3 – 24,000 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 reverb program 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.
