Echo Rhythms
Echo rhythms are divisions of the tap inter-
val you've selected for Vortex. The ECHO 1
÷
and ECHO 2
÷
controls allow you to set
independent rhythms, which will always be
related to the tap interval, for each of Vortex's
two delay lines.
For example, if you tap in a whole note
interval (4 beats between taps), the param-
eter value 4 corresponds to quarter-note
echoes, 8 corresponds to eighth-note ech-
oes...64 to sixty-fourth-note echoes.
Tap intervals in Vortex can be as long as
28 seconds, allowing long phrases of music,
rather than single beats, to determine tempo.
Whenever Vortex is turned on, the tap
interval will return to the default value. (1=a
quarter-note at 65 bpm)
The ability to set different rhythmic divi-
sions for Vortex's two echoes allows you to
set up some very interesting patterns. For
example:
1. Load any effect with a dual echo configu-
ration, such as preset 8. DUO B.
2. Tap in a whole note interval (4 beats
between taps).
3. Turn the Parameter knob to ECHO 1
÷
,
and set the VALUE knob to 16. This will
give ECHO 1 a sixteenth-note rhythm.
4. Select ECHO 2
÷
, and set its VALUE to 8,
giving ECHO 2 an eighth-note rhythm.
Now, you can tap any interval, and the
relationship between ECHO 1 and ECHO 2
rhythms will be maintained — and still be
synchronized with the tempo. (ECHO 1 will
always have a rhythm which is twice as fast
as that of ECHO 2.)
