19. Echo Short
20. Echo Long
This effect can be used to create expansive echo effects -- with
independentiy variable ieft and right channei echo delays and
feedback.

Left Channel Delay (Lch DLY): 0.1 — 250 milliseconds
After the delay set by this parameter, the first left-channel
echo will appear, Subsequent echoes will appear at the
same time interval, the number of echoes depending on the
setting of the feedback gain setting for the corresponding
channel.
21. Stereo Flange
This effect produces a pleasant “swirling” sound which can ef­
fectively thicken and add warmth to the sound of an instrument.
The flanging effect is produced by varying the delay between
two identical signals, thus producing a complex varying "comb
filter” effect.

■(TIME)
Modulation Frequency (MOD. FRQ): 0.1 Hz — 20 Hz
Sets the speed of modulation, and hence the rate at which
the effect varies.
Modulation Depth (MOD. DEPTH): 0% —100%
Sets the amount of delay time variation, thus adjusting the
depth of the effect.
Modulation Delay (MOD. PLY): 0.1 —100 milliseconds
This sets the basic delay time from the initial direct sound to
the beginning of the flange effect.
Feedback Gain (F.B. GAIN): 0% — 99%
Determines the amount of flange signal which is fed back to
the input of the processor for further modulation. More feed­
back increases the overall complexity, “strength” and decay
time of the effect.
Left Channel Feedback Gain (Lch F.B): -99% — - f 99%
Adjusts the number of echoes that follow the direct signal -
from zero to a virtually infinite number of echoes at the
maximum setting.
Right Channel Delay (Rch DLY): 0.1 — 250 milliseconds
Same as Left Channel Delay, but affects the right channel
only.
Right Channel Feedback Gain (Rch F.B): -99% — .f99%
Same as Left Channel Feedback Gain, but affects the right
channel only.
High Frequency Feedback (HIGH): x0.1 —x1.0
Controls feedback in the high-frequency range. The high-
frequency feedback is reduced as the value of this parame­
ter is decreasxed.
