Chapter 4: Effect parameters
Stereo Pianger — FLG
The stereo flanger effect splits the signal into two, delays one signal by a modulated delay time,
then mixes the signals together. It produces a comb filter effect that sweeps up an down the audio
bandwidth. Sometimes described as a swishing or tunneling effect, it is a coarse form of phaser
effect.
SPD Modulation Speed 0.1 Hz - 20 Hz
DEP Modulation Depth 0 ~ 100%
DLY Delay Modulation 0.1 - 1 0 0 msec
The delay time before the signal is
modulated. Also affects the frequency range
that is modulated.
FB Feedback 0 - 100%
The amount of effected signal that is fed
back into the effect.
WID Sound Image Width 0 - 1 0
0 = mono.
10 = wide stereo.
MIX Mixing Balance 0- 100%
0 = dry signal.
50 = 50% flanger effect 50% dry signal.
100 = 100% flanger effect.
LVL Output Level - -30 dB - +6 dB Sets the output level of the effect.

Symphonic — SYM
The symphonic effect splits the signal into two, modulates one signal, then mixes the two signals
together. It produces a rich thickening type effect, similar to a chorus effect — like a symphony
of guitars playing together.
SPD Modulation Speed 0.1 Hz - 20 Hz
DEP Modulation Depth 0 - 1 0 0 %
DLY Modulation Delay 0.1 - 100.0 msec
The delay time before the signal is
modulated.
* A short delay time (1.9 msec or less) will
affect the depth of pitch modulation.
WID Sound Image Width 0 - 1 0
0 = mono.
10 = wide stereo.
MIX Mixing Balance 0 - 100%
0 = dry signal.
50 = 50% symphonic effect 50% dry signal.
100 = 100% symphonic effect.
LVL Output Level - oo, -30 dB - +6 dB Sets the output level of the effect.
