Note that the sensitivity can also be used to tweak the envelope tracker for different musical
instruments: for example, a high output bass and a low output bass may need different values of
sensitivity to get the same feel. However, we recommend that the global

SEn parameter in custom

(see “Custom settings” on page 27) is used instead to adjust for instrument characteristics so that
it is easier to switch between different instruments and to make it easier to exchange presets with
other users.

Pitch mode

If a filter is in pitch mode, the following sub-parameters are used:

The pitch mode can be set to either pitch-track or pitch-bend using the

tyP sub-parameter. These

innovative effects use sonuus’ unique, highly acclaimed, pitch detection and tracking technology.

Pitch-track (trA).

In pitch-track mode, the cutoff frequency of the Wahoo filter is set to follow the

pitch of the notes that you play. There are three parameters that control how this happens. The pitch
tracking can be offset from the pitch of the notes you play by adjusting the

FrE frequency sub-

parameter— a positive number can move the filter frequency higher by up to 4 octaves; a negative
number can move the filter frequency lower by up to 4 octaves. The other two parameters that
control the pitch tracking are

freq-hi and freq-lo in the filter set-up. The pitch tracking frequency is

limited to always be between

freq-hi and freq-lo. You can picture pitch tracking as a filter that moves

with the pitch of your notes within frequency limits you define ( just like when a synthesizer’s filter is
set to “keytrack” mode). It allows you to create interesting tonal effects, including synth-like sounds,

Top Tip:

Pitch tracking is monophonic (it can only track single notes) but you can still

play chords in

pitch mode: the Wahoo will track the dominant note. For best

control of the effect in

pitch mode, play single notes clearly.
