Harmony and Tuning with the Voice
Processor
Harmony
Here's where we can go into a little more depth about harmonies.
We've tried to keep it practical, focusing on what Voice Proces-
sor can do for you.
Harmony Modes
The Voice Processor has four different harmony modes, which
give four unique methods of creating harmony. Once we get into
describing the more complex harmony modes, we'll be showing
you examples based on the C major scale. If you are unfamiliar
with this scale we've shown C major here.
Notes Mode
In this mode, you provide the Voice Processor with specific note
information to determine the pitch of the harmony voices. This
is the most direct and flexible way of creating harmonies, allow-
ing you to weave complex melodies and counter harmonies irre-
spective of your lead vocal.
Shift Mode
Also known as "Fixed Interval", this takes the pitch of your lead
voice and creates harmonies a set number of semitones away,
based on that pitch. The method of creating harmonies, using a
fixed number of semitones relative to an input note or pitch, is
called chromatic harmony, the theory of which we'll go into later.
We consider this type of harmonizing to be non-intelligent
because Voice Processor is not set to any particular key or scale.
These are pure, parallel harmonies. The most common shift har-
mony voices are the 5th (7 semitones) and octave (12 semi-
tones), ranging from two octaves below the input to two octaves
above the input pitch.
Below is the C Major scale, showing third above chromatic scale
harmony, as used in Voice Processor Shift Mode.
Black = Lead, Grey = Harmony
