Yamaha SPX2000 Delay + Reverb (PRESET bank) Delay Reverb (PRESET bank)

SPX2000—Owner’s Manual 75

Composite

Delay + Reverb (PRESET bank)Delay → Reverb (PRESET bank)

Delay + Reverb separately applies delay and reverb to the original sound, and then mixes the results.

Delay → Reverb applies delay to the original sound, and then applies reverb.

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

Delay: DELAY L, DELAY R, FB.DLY, FB.GAIN, DELAY HI

Reverb: REV TIME, REV HI, INI.DLY, DIFF., DENSITY

Balance between delay and reverb: DLY/REV, DLY.BAL

Filter/equalizer: HPF, LPF

Tempo synchronization: SYNC, NOTE L, NOTE R, NOTE FB, TEMPO

Output level: OUT LVL, MIX BAL.

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.

REV HI 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. REV HI is the

decay of the high-frequency range.

INI.DLY 0.0—500.0 ms Delay of the early reﬂections relative to the original sound. This value also affects the delay until

reverberation is heard.

DIFF. 0—10 Diffusion of the sound to left and right. Increasing this value will make the reverberation more

spaciousness.

DENSITY 0—100% Density of the reverberation. Increasing this value will make the reverberation smoother. You can

create unique effects by lowering this value.

DELAY L

DELAY R 0.0—1000.0 ms Delay relative to the original sound. DELAY L is the L channel delay, and DELAY R is the R channel

delay.

FB.DLY 0.0—1000.0 ms

Delay added when the signal is fed back. The delay from the original sound to the ﬁrst delay is set by

the DELAY L and DELAY R values, but the delay of subsequent repeats will be each DELAY + FB.DLY.

FB.GAIN –99%—+99%

Amount of feedback for the delay sound. This indicates the ratio by which the level is reduced for

each repetition of the effect. For example with a setting of +50, the level of the delay will decay to

50% → 25% → 12.5% as it is repeated. Negative (–) values invert the phase of the feedback.

DELAY HI 0.1—1.0

Amount of feedback for the high-frequency portion of the delay. This is speciﬁed as a proportion

of FB.GAIN. If this value is 0.1, the feedback amount will be 1/10th of FB.GAIN; if this value is 1.0,

the feedback amount will be the same as FB.GAIN.

Parameter name Range Explanation

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.

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.

HPF Thru, 21.2 Hz—8.00 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 50.0 Hz—16.0 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.

DLY/REV 0—100% (Delay + Reverb only) Balance between the delay and reverb. A setting of 0% outputs only the

delay; a setting of 100% outputs only the reverb.

DLY.BAL 0—100% (Delay → Reverb only) Amount of reverb. Raising this value will strengthen the reverb effect. At a

setting of 0% only delay will be heard.

SYNC ON, OFF

Switches tempo synchronization on/off. If this is ON, the delays will synchronize to the tempo syn-

chronization source speciﬁed by “TEMPO SOURCE” (page 23). Each NOTE value will be set to the

synchronized tempo value.

NOTE L

NOTE R

NOTE FB

*a.

These parameters are used for tempo synchronization. If SYNC is ON, each DELAY value will be

set according to the corresponding NOTE value and TEMPO. If SYNC is OFF, this value is ignored.

TEMPO 25—300

This parameter is used for tempo synchronization. If SYNC is ON, the various DELAY values will

be set according to this value and the corresponding NOTE values. If SYNC is OFF, this value is

ignored.
