Usage Tips
•
  CHOIR Evo is available in mono and stereo 
versions and, depending on the capabilities of 
your host program, a mono -> stereo version 
(which in most cases is the preferred routing). 
In the case of the stereo version, CHOIR Evo 
processes only the left channel. CHOIR Evo 
is dramatically more effective with the voices 
panned across the stereo spectrum, so if at 
all possible, try always to use it with stereo 
output.
•
  The real power of CHOIR Evo comes not as 
a processor for one voice, but as a processor 
to assign to each of a number of harmony 
parts. Even if you have only one singer, have 
them overdub the basic harmony parts and 
then process those parts through THROAT 
Evo to give each the character of different 
voices. Then assign an instance of CHOIR 
Evo to each of those parts and create your 
vocal ensemble.
•
  Alternatively, create harmony parts by 
processing a single vocal part through a 
harmonizer and then assigning each  
individual harmonizer output to an instance  
of CHOIR Evo.
•
  Keep in mind that the greater the number of 
voices, the greater the CPU usage. If you will 
be using multiple instances of CHOIR Evo,  
it might be wise to limit each instance to 4 or  
8 voices.
•
  Along those same lines, even if you have tons 
of CPU power, more is not always better. 
Match the choir size to the style of your  
music. Not every song needs the Mormon 
Tabernacle Choir.
•
  Experiment with different combinations of 
the Pitch and Timing controls. They can create 
dramatically different vocal ensembles. With 
Timing at its minimum and substantial Pitch 
Variation, you have a choir that’s rhythmically 
tight but a bit loose with intonation. Conversely, 
reversing those settings gives you a group 
that’s solidly in tune, but rhythmically loose. 
And there are of course many variations in 
between. Match the performance style to the 
style of your music.
•
  For best performance, CHOIR Evo requires a 
clean, pitched monophonic signal. If CHOIR 
Evo can not reliably detect the pitch of the 
input, either because of a noisy or effected 
signal or because the input is not a single 
monophonic voice, it will apply Timing 
variations only.
