Chapter 4: Effect parameters
Auto Pan — PAN
The auto pan effect moves the signal continuously across the stereo image, i.e., between the left
and right outputs. It provides a drifting type effect that is ideal for slow atmospheric songs and
can help to maintain interest in repetitive guitar riffs. The panning speed is controlled by the
modulation speed parameter.
SPD Modulation Speed 0.1 Hz ~ 20 Hz
DEP Modulation Depth 0 - 1 0 0 %
DIR Direction
L L —> pans the signal from L to R.
<- R R <— pans the signal from R to L.
L <-» R L R pans the signal from L to R to L, etc.
MIX Mixing Balance 0 - 1 0 0 %
0 = dry signal.
50 = 50% auto pan effect. 50% dry signal.
100 = 100% auto pan effect.
LVL Output Level - oo, -30 dB - +6 dB Sets the output level of the effect.

Tremolo — TRM
The tremolo effect modulates the signal amplitude to produce regular variations in volume level,
similar to vocal vibrato. The modulation waveform can be set to sine, triangular, or square,
offering three tremolo effect variations.
SPD Modulation Speed 0.1 Hz - 20 Hz
DEP Modulation Depth 0 - 1 0 0 %
