PITCH SHIFT
Pitch Shifting is used to produce harmony notes (up to four, depending on the current
configuration) based on the pitch of the input signal. The Intellipitch provides four different
pitch shift configurations—two for
chromatic shifting, one for intelligent shifting and one for
a special reverse shift effect.
Pitch Shift Types
Chromatic pitch shifting produces a harmony note that is always a
fixed chromatic interval (or number of semitones) above or below the
input note. Each harmony voice may be of any fixed interval—from to one
octave above the input signal to two octaves below—and is adjustable in
20 cent increments. Increments of one cent (1/100th of a semitone) are
also available for fine adjustment via the Fine parameter.
Intelligent pitch shifting differs from chromatic pitch shifting in that
the harmony notes that are produced are always generated diatonically
within a user-specified key and scale type. Therefore, any input note
played in the prescribed key will result in harmony notes that are also in
the proper key.
Reverse shifting is a special effect that allows for the delayed pitch
sample to be played back in reverse after its prescribed delay time has
expired.
Pitch Shift Configurations
The Intellipitch provides four different configurations for pitch shifting.
The pitch shift configurations provided by the Intellipitch can be summa-
rized as follows:
Hush; Pitch Shift; Delay provides four voices that can each be used for
chromatic pitch shifting and/or delay, as well as HUSH noise reduc-
tion.
Hush; Pitch Shift; Delay; Reverb provides two voices that can be used
for chromatic pitch shifting and/or delay, as well as an additional
dedicated delay line. This configuration also provides HUSH, reverb,
and ducking functions.
Hush; Intelligent Pitch Shift provides two voices that can be used for
intelligent (or diatonic) pitch shifting and/or delay.
Hush; Reverse Pitch Shift provides two voices that can be used for
pitch shifting with a special reverse effect. Reverse shifting allows for
the delayed pitch sample to be played back in reverse after its pre-
scribed delay time has expired.
