Digitech Vocal Harmony Processors (part 5)


The first thing you will notice about using the Studio Vocalist is how precise
the harmonies are. This will probably come as quite a novelty after years of
trying to get real singers to be as precise as this, and early Queen style vocal
harmonies come out of the speakers almost unbidden. Eventually, you may wish
for something a little more like what ordinary people can manage, so Digitech
have thoughtfully provided a number of 'humanising' features. These are Gender,
which I have already mentioned, Detune, Vibrato, Scoop and Timing. Gender here
isn't just a matter of being male or female. You can choose which you want to
be and then set a value from -50 to +50. A masculinity or femininity value if
you like. The idea is to make multiple harmonies sound as though they are coming
from different people instead of clones of the soloist, and it works. The Detune
function adds what Digitech call 'a subtle out-of-tuneness' to the harmony voices.
Human voices are rarely perfectly in tune and Studio Vocalist doesn't have to
be either. Vibrato is another human feature, one that often becomes more pronounced
the older the singer is! Vibrato parameters include Depth, Rate, Type (sine,
square wave, sawtooth up, sawtooth down), Delay and Randomness. Scoop is a technique
(or do I mean mannerism?) where a singer hits a note slightly below pitch and
then slides up to correct pitch. Scoop can be introduced randomly, or via MIDI
velocity data. Timing is a variable delay before the onset of a harmony note,
which also can be randomised.

With all this functionality, you might think that creating and storing programs
would be pretty difficult, since each time you use the unit you will probably
require a different harmony. Fortunately, Digitech have provided a 'Style' feature
where you can edit harmonies and each of the humanising functions in detail,
and then store them independently as Styles. Styles can be mixed and matched
as necessary to create new harmony effects. I won't say that it is the work
of a moment to create a harmony that exactly suits what you are trying to achieve,
but if you compare it with the alternative of writing it all down and working
with a group of singers, then I think you will see it in its correct proportion.
