Voice Processor Preset: Filter & Hard Tune
This page contains the Filter and HardTune effects, which dra-
matically change the sound’s character.
Filter
This effect uses steep filters to emulate the sound of radios,
phones and devices that generally degrade the audio signal.
(Filter) On/Off
This button allows enabling/disabling of the Filter block. It is the
same control found in the “Easy Preset” page.
Set
Use this menu to choose a pre-programmed Filter Set. The Rout-
ing and Gate Threshold parameters are not part of the Set. This
corresponds to the option selected in the “Easy Preset” page.
Level
Sets the level for the overall Filter effect in the current preset.
Routing
Selects where the Filter effect is inserted into the signal path for
maximum flexibility. The options are:
Off No routing.
Lead Filter is inserted on the Lead voice only. Harmo-
nies and Doubling are unaffected.
Harm+Double Filter is inserted on the Harmony+Double path
only.
Voices Filter is inserted on both the Lead, Harmony and
Doubling voices.
Lead FX Filter is inserted on the Lead send to the μMod,
Delay and Reverb effect sends. Lead voice will be
clean.
Harmony FX Filter is inserted on the Harmony send to the
effects. Lead and Harmony voices will be clean.
Low Cut / Hi Cut
Sets the cut-off frequency for these very steep low and high
shelving filters.
Gate Threshold
A gate, separate from the main Gate under the “Voice Processor
Setup: Mic Tone” page is used to help prevent feedback when
using the Filter with presence filtering that can introduce feed-
back in a live environment. This parameter sets how loud you
must sing in order to open the gate.
HardTune
This effect is a pitch corrector that has been optimized to pro-
duce corrective pitch correction as well as obvious effects made
popular by a number of artists.
Note: This effect only works when a chord is recognized.
(HardTune) On/Off
This button allows enabling/disabling of the HardTune block. It
is the same control found in the “Easy Preset” page.
Set
Use this menu to choose a pre-programmed HardTune Set. This
allows you to quickly choose an effect close to what you want
instead of having to go directly into the individual parameters
each time. This corresponds to the option selected in the “Easy
Preset” page.
Rate
Rate determines how fast the algorithm pulls you toward scale
tones. A value of 0 is off and a value of 100 is instant resulting in
something like the infamous “Cher” effect where the pitch cor-
rection effect is stair-stepped and obvious when using non-chro-
matic scales (those with at least a whole tone jump between most
of the scale tones). Usually, values around 20 yield acceptable
results for smooth, corrective pitch correction.
Shift
Sets the a relative shift in semitones above or below the input
vocal. This is useful for transposing or creating character voices
while simultaneously pitch correcting.
Window
Allows you to determine how close to a valid scale note you have
to be before the algorithm corrects you. For example, a value of
80 cents means that only when you are singing within +/- 40
cents away from the target scale note will you be corrected. The
maximum value is 600 cents. At maximum, a custom scale could
be created with only one note for special effects. In a Major scale
having no more than 100 cents on either side of any scale tone a
setting of 200 would result in fulltime correction activity.
