Description
Harmony Mode
Method by which musical input is sent to
VoicePro.
Diatonic
Refers to the tone structures in major
and minor scales. Knowledge of these
scale structures is the "intelligence"
VoicePro uses to produce automatic
harmony.
Interval
The distance between two pitches
Notes Mode
Fully manual harmony mode where notes
and chords performed on a MIDI
keyboard are used to select the fixed
harmony pitches independent of the pitch
of the sung note.
Notes 4Ch Mode A second Notes Mode where each note
is received on a different MIDI channel
from a sequencer program, enabling
unique pitch bends on each channel.
Chord Mode
An intelligent harmony mode where a
sequence of chords played on a MIDI
keyboard are interpreted to produce
musically correct pitches that move
according to the pitch of the sung note.
Scale Mode
An automatic harmony mode where you
set only the key and scale of your song.
Usually, no on-going musical input from a
keyboard is required.
Shift Mode
This is the one non-intelligent harmony
mode where a fixed interval is set for
each harmony voice that is maintained
throughout the song.
Humanization
Various methods by which VoicePro
introduces random variations to the
sound that mimic human deviations in
pitch and timing.
