FOOTSWITCH

The menu allows you to set the following overall audio processing parameters:
AUDIO
(Min, 1-9, Max): this raises and lowers the frequency threshold at
ESS SENSITIVITY
which an "ess" sound is passed dry or harmonized. At high settings, "ess" sounds
will be pitch shifted, potentially causing a grainy "ess" sound but also yielding supe-
rior pitch tracking. At low settings, your "ess'es" will sound natural, but at the risk of
tracking errors on some voices.
have experience tracking errors.
- (0 - 100%): tweak this setting to silence unwanted sibilants, especially
ANTI FEEDBACK
from vocals. It works by lowering the level of the high frequencies that initially create
the "sss" sound.
(0% - 100%): reduces the effect of low frequency leakage into the
BASS REJECT
microphone. Tweak this if your bass player is a little to loud and causing weird trig-
gering effects.
(440H ) (-64c - +63c): sets the offset from the tuning frequency of 440Hz, or
TUNING Z
the "A" note just above middle "C" ("C", for those of you wondering, is 261.63Hz).
Use this to change VoicePrism's 440Hz reference to match a piano that has shifted
pitch but is still in tune relative to itself. This feature is also helpful when working
with tracks recorded using guitars tuned by ear, rather than by machine, allowing
you to match the guitar's more liberal interpretation of the reference A note.
You can configure the buttons for a one or three button footswitch by twisting the
softknob under the button description. VoicePrism is factory configured for a one
button footswitch, the Right button which is initially set to
Middle buttons are set to
