SPX2000—Owner’s Manual 33

Reverb
Reverb & Gate (CLASSIC bank)

This is a gated reverb (also called gate echo). You can use this effect to add only a portion of the reverberation.

Each aspect of the sound is controlled by the following effect parameters.

Reverberation: REV TIME, HI.RATIO, DELAY

Gating: TRG. LVL, HOLD, RELEASE, MIDI TRG

Filter/equalizer: HPF, LPF
Output level: OUT LVL, MIX BAL.
Parameter details
■Basic parameters
Effect list

The following table shows the default parameter values for the effect belonging to the Reverb & Gate type (CLASSIC bank).

Parameter name Range Explanation
REV TIME 0.3—99.0 s Reverb time. This is expressed as the time over which reverberation at 1 kHz will decay by 60 dB.
HI.RATIO 0.1—1.0
Reverb time for the high-frequency range, expressed as a proportion of REV TIME. If this value is
0.1 the time will be 1/10th the REV TIME; if it is 1.0 the time will be the same as the REV TIME.
You can adjust these values to simulate the absorptiveness of the walls and ceiling. HI.RATIO is the
decay of the high-frequency range.
DELAY 0.0—500.0 ms Delay of the reverberation relative to the original sound.
HPF THRU, 32 Hz—1.0 kHz
A filter that cuts the low-frequency portion of the effect. Frequency components lower than the
frequency specified here will be cut. With a setting of THRU this filter will do nothing. This filter
does not affect the original sound.
LPF 1.0 —11 kHz, THRU
A filter that cuts the high-frequency portion of the effect. Frequency components above the fre-
quency specified here will be cut. With a setting of THRU this filter will do nothing. This filter does
not affect the original sound.
TRG. LVL 1—61 The level at which the gate is triggered. Increasing this value will raise the level of original sound
required to open the gate.
HOLD*a
*a. The range of this parameter depends on the sampling frequency at which the SPX2000 is operating.
44.1 kHz: 0.02 ms—2.13 s
48 kHz: 0.02 ms—1.96 s
88.2 kHz: 0.01 ms—1.06 s
96 kHz: 0.01—981 ms
The minimum time that the gate remains open. Even when the original sound falls below the TRG.
LVL, the gate will remain open for the time specified by this value.
RELEASE*a
44.1 kHz: 6—32000 ms
48 kHz: 6—29400 ms
88.2 kHz: 3—16000 ms
96 kHz: 3—14700 ms
The release time of the gate. This is the time from when the gate begins to close until it is com-
pletely closed. Higher settings of this value will make the gate close more slowly; i.e., the volume
that passes through the gate will decrease more slowly.
MIDI TRG ON, OFF
Specifies whether MIDI messages will be used to trigger the gate. If this is ON, the gate will open
when a Note-on message with note number C1 or higher is received. In order to enable MIDI mes-
sage reception, you must specify the MIDI port and MIDI channel. For details, refer to “Prepara-
tions for using MIDI” on page 88.
OUT LVL 0—100% Output level after the original sound and effect sound have been mixed. Decrease this value if you
want to lower the output. At a setting of 0% there will be no output.
MIX BAL. 0—100% Balance between the original sound and effect sound. At a setting of 0% only the original sound
will be output; at a setting of 100% only the effect sound will be output.
No. Effect name REV TIME HI.RATIO DELAY HPF LPF TRG.LVL HOLD*a
*a. The default value of this parameter depends on the sampling frequency at which the SPX2000 is operating. The value shown in the table is for fs =
96 kHz.
