 Freeze button: When selected, the current analysis sound spectrum is held
indefinitely. This can capture a particular characteristic of the source signal, which is
then imposed as a complex sustained filter shape on the Synthesis section. While
Freeze is selected, the analysis filter bank ignores the input source, and the Attack
and Release parameters have no effect.
Using a spoken word pattern as a source, for example, the Freeze parameter can
capture the attack or tail phase of an individual word within the pattern; for example
a vowel sound.
Another use of the Freeze parameter is to compensate for peoples inability to
sustain sung notes for a long period without taking a breath. If you wish the
synthesis signal to be sustained when the analysis source signal is not, Freeze can be
used to lock the current formant levels (of a sung note), even during gaps in the
vocal part, such as between words in a vocal phrase.
 Analysis In pop-up menu: Sets the analysis signal source. The choices are:
 Track: Sets the audio track into which the EVOC 20 TrackOscillator is inserted as
the analysis signal.
 Side Chain: Sets the Side Chain (another audio track) as the analysis signal. You
choose the Side Chain source track from the Side Chain pop-up menu at the top of
the EVOC 20 TrackOscillator window.
Note: If Side Chain is selected, and no Side Chain track is assigned, the tracks signal is
used as the analysis source.
