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.
