f HARDTUNE KEY
Sets HardTune’s source for musical information.
Most pitch correction products require either
scale information, offline editing or MIDI perfor-
mance to yield correction. VoiceLive Rack goes
one further and allows you to play your guitar or
MIDI keyboard normally and get the Hardtune
effect.
When HARDTUNE KEY is set to FOLLOW
HARMONY the HardTune effect will follow the
same source as the harmony voices. Thus:
• If a guitar or MIDI keyboard is controlling your
harmony voices, it would also control the
HardTune effect.
• If Harmony is set to a fixed Key and Scale,
these same parameters will be used by the
Hardtune effect.
• When Harmony is set to SHIFT, MIDI NOTES,
or MIDI NOTES 4 CHAN, HardTune will use
its own key and scale parameters.
When HARDTUNE KEY is set to MANUAL/
CUSTOM a different Key and Scale may be set
with the KEY and SCALE parameters at the bot-
tom of the tab.
f HARDTUNE 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-chromatic scales (those with at least
a wholetone jump between most of the scale
tones). Usually, values around 20 yield acceptable
results for smooth, corrective pitch correction.
f HARDTUNE AMOUNT
Allows you to soften the correction effect. A
value of 50% for example will only pull you half-
way toward a correction scale target at the speed
set by the HARDTUNE RATE parameter. For a
true HardTune sound, set it to 100%
f HARDTUNE SHIFT
Sets the a relative shift in semi-tones above or
below the input vocal. This is useful for transpos-
ing or creating character voices while simultane-
ously pitch correcting.
f HARDTUNE 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.
f KEY & SCALE
These set the musical map that the HardTune ef-
fect will correct to only when HARDTUNE KEY
is set to MANUAL/CUSTOM.
The manual scale selection is different from the
ones available for Harmony. They are:
• Major
• Minor-Har (harmonic minor)
• Minor-Nat (natural minor)
• Minor-Asc (ascending melodic minor)
• Chromatic (no key or scale required)
