Effect list
The following tables show the default parameter values for the effect belonging to the Delay L,C,R type (PRESET bank).
■Basic parameters
■Fine parameters
Echo (PRESET bank)
These effects add two delays; one each to the L and R channels. This is similar to Stereo Delay (page 40), but Echo mixes the
L/R channel delay sounds for feedback. You can specify the amount of feedback sent from the L channel to the R channel, and
from the R channel to the L channel.
Each aspect of the sound is controlled by the following effect parameters.
Delay sound:
DELAY L, DELAY R, FB.DLYL, FB.DLYR, FB.G L, FB.G R, L
→
R FBG, R
→
L FBG, HI.RATIO
Tempo synchronization: SYNC, NOTE L, NOTE R, NOTE.FBL, NOTE.FBR, TEMPO
Filter/equalizer: HPF, LPF
Output level: OUT LVL, MIX BAL.

Parameter name Range Explanation
DELAY L
DELAY R
0.0—1350.0 ms Delay relative to the original sound. DELAY L indicates the L channel delay, and DELAY R indi-
cates the R channel delay.
FB.DLYL
FB.DLYR
0.0—1350.0 ms
Delay added to the feedback. FB.DLYL indicates the L channel delay, and FB.DLYR indicates the R
channel delay. The delay from the original sound to the first delay sound is DELAY L or DELAY R;
the delay of the subsequently repeated sound will be DELAYL+FB.DLYL or DELAY R+FB.DLYR.
FB.G L
FB.G R –99%—+99%
Amount of feedback for the delay sounds. This indicates the ratio by which the level is reduced
when repeating the effect. For example with a setting of +50, the level of the delay sound will decay
to 50% → 25% → 12.5% as it is repeated. Negative (–) values invert the phase of the feedback.
FB.G L indicates the feedback amount for the L channel, and FB.G R for the R channel.
L->R FBG –99%—+99% Amount of feedback from the L channel to the R channel. Negative (–) values invert the phase of
the feedback.
R->L FBG –99%—+99% Amount of feedback from the R channel to the L channel. Negative (–) values invert the phase of
the feedback.
HI.RATIO 0.1—1.0
Amount of feedback for the high-frequency portion of the delay sound. This is specified as a pro-
portion of FB.G. If this value is 0.1, the high-frequency feedback amount for the L channel will be
1/10th of FB.G L, and the high-frequency feedback amount for the R channel will be 1/10th of
FB.G R. If this value is 1.0, the feedback amount will be the same as FB.G L/FB.G R.
NOTE: If the FB.G L, FB.G R, L->R FBG, or R->L FBG values are raised excessively, oscillation will occur, and the signal will not decay.
Please use caution.
