for example by configuring a low-pass filter to remove the harmonics of your instrument’s signal to
leave only the fundamental tone. The tracking will only follow your playing exactly when the curve
sub-parameter of the filter

ShP parameter is set to linear (Lin). If one of the other setting is selected

(

Lo9–hi9), you will change the point at which the filter follows your playing. Although this will be less

predictable, you can create some nice effects like this.

Pitch-bend (bEn).

In pitch-bend mode, when you bend a note, the cutoff frequency of the filter

moves. You set how much of a bend should map onto the maximum cutoff control—this is set in
semitones via the

S.tn sub-parameter and can be between 1 and 36 semitones. Obviously, the larger

values are not applicable to note-bending with your fingers; they apply to bending using a whammy/
tremolo bar. The extremes of the pitch-bend are then mapped to the values of

freq-lo and freq-hi:

the limits you have set for the filter cutoff frequency. The reference point of the bend is set by the

rEF

sub-parameter. The reference point is the filter cutoff frequency before you apply a bend. For
example, if the reference is bottom, then the filter cutoff is at

freq-lo before you bend. Bending up by

S.tn causes the filter cutoff to increase to freq-hi. The effect of different reference points is shown
in the diagram below.

Top Tip:

Pitch tracking is optimised for different instruments. You can choose the

instrument setting in the custom settings (see “Custom settings” on page 27)

to select between guitar, 4-string bass and 5-string bass.
