Lexicon VORTEX - MANUAL 2 User Manual page 18

Vortex echo divisions are calculated with
16-bit acuracy. This ensures that the rhyth-
mic relationships between ECHO 1 and
ECHO 2 are highly accurate and stable, even
for unusual polyrhythms such as 2 against 9,
or 11 against 13 — patterns that would be
extremely tedious, and perhaps impossible,
to set up on another effects processor.
Try setting up some patterns such as 3
against 2, 7 against 9, etc. — they're all a
snap with Vortex.

The maximum delay time for one echo in
Vortex is 923 milliseconds. The maximum
• • •
delay time for configurations which use
Vortex's two delay lines in series is 1846 ms.
In theory, this would require you to calculate
the allowable tap interval/rhythmic division to
make sure the times you enter fall below the
limit. Vortex, however, not only performs this
tedious calculation for you, but lets you ig-
nore the whole issue of maximum delay
times, by intelligently processing whatever
combination you enter.
If a tap interval/ rhythmic division combina-
tion is selected which exceeds the maximum
delay, Vortex will divide the selected delay
time in half until it falls below the limit. For
example, if a whole note won't fit, Vortex will
give you a half note. If a half-note won't fit, it
will give you a quarter note, and so on, until
a compatible value fits. This way, no matter
what tap interval and rhythmic division you
select, the musical relationship between
them is preserved.
