The Voices Tab
The Voices Tab allows editing of settings you need most for each harmony
voice. The number of parameters differs depending on the harmony mode in the
current preset.
Level
Here you can mix the relative levels of each of the four voices. There is also an
"Off" value which will disable any voice. Setting all four voices to 0dB (full) will
most likely cause output clipping with hot inputs. If this occurs, you can either
reduce the input level with the IN slider or reduce the level of each voice. Note
that any voice whose level is set to Off will ignore MIDI. If you want to use
automation to fade-up a voice in a MIDI controlled harmony mode, you should
start at -60dB and not Off.
Voicing (Scale mode), Offset (Shift mode), Position (Chord mode)
These parameters allow you to arrange the intervals of your four singers above
and below the lead singer. They are available in all modes except Notes and
Notes 4CH and they work slightly differently in each harmony mode:
In Shift Mode, the Offset values range from -24 semitones to +24
semitones in a fixed, non-diatonic interval relative to the input melody.
In Scale Mode, the Voicing parameter specifies a diatonic interval relative
to the input. The range is -2 octaves to +2 octaves. For example, a setting
of +3rd will result in a harmony voice a third above the input voice, which
could be major or minor depending on the current Key and Scale settings.
Values of for example, ++3 or --5 are over an octave away from the input
note.
In Chord Mode, the Position parameter determines a more general
relationship between the harmony note and the input note. The harmony
intervals relate to the chords played on your MIDI keyboard. A setting of
"Up1" generally places the harmony voice a third above the input voice.
In Notes and Notes 4CH modes, the Voicing parameter is not shown or
editable because intervals are determined by the incoming MIDI notes.
Pan
Each harmony voice can have its own stereo pan position. Spreading the
harmony voices within the stereo field can help de-couple the harmony voices
from the input voice, resulting in more natural sounding harmonies. Left = “-”,
Right = “+”
Gender
This parameter shifts the formants (often called the gender) of the harmony
voices. Use it to alter the character of the voice ranging from -50 (a big person
with a deep, resonant voice) to 0 (no change) to +50 (mice/alien sound).
