The desired harmony mode is selected with
the Harmony Source popup menu. Depending
on which mode you select, various of the other
controls in this section will be either activated
or disabled as necessary. Rather than discuss
each control separately, we’ll look at all of the
controls that function in each mode.
Here’s how they all work:
Fixed Interval Mode
When Fixed Interval
mode is selected, the
Interval popups in the
individual harmony
voice channels are
enabled and all of the other controls in the
Harmony Control section are disabled.
In this mode, each enabled harmony voice
tracks the original input at the interval defined
by the number of semi-tones up or down
selected in the voice’s Interval popup.
Since no allowance is made for diatonic scale
tones, using this mode in conventional diatonic
harmony with any intervals aside from octaves
will almost certainly result is dissonant, out-of-
scale notes. As a result, this mode is best for
drones, chants and other applications where
absolutely parallel harmony is desired.
NOTE: In Fixed Interval mode,
all of the input audio’s pitch
gestures are followed regardless
of the Naturalize setting. Increasing the
Naturalize setting above 0 will actually
expand the range of those gestures.
Scale Interval Mode
When Scale Interval
mode is selected, the
Key/Root and Scale
popups are enabled
(along with the
Interval popups in the individual harmony voice
channels) and all of the other controls in the
Harmony Control section are disabled.
In Scale Interval mode, each harmony
voice tracks the original input at the interval
defined by the scale degree selected
in its Interval popup in combination
with the Key and Scale settings.
In contrast to the Fixed Interval mode, this
mode always chooses harmony notes that fall
in the selected key and scale. For example, If
you have selected C Major as the key and set a
harmony voice’s Interval popup to +3rd, when
the input is C, the harmony voice will sound at
E (a major 3rd). However, when the input is D,
the harmony voice will sound at F (a minor 3rd).
IMPORTANT NOTE: An exception
to the above is when Unison or
any Octave interval is selected.
In that case, the harmony voice will track
the input note-for-note, regardless of
whether they are scale notes or not.
