About the Parameters
Vortex parameters, in addition to providing
familiar mix and level controls, allow you to
access dimensional, rhythmic, and dynamic
aspects of each effect. These controls make
Vortex much more like a musical instrument
than a simple effects box — they let you
play
Vortex's unique effects.
The MIX and OUTPUT controls, which
have the same function in each effect, are
described here. Certain other parameters,
such as the modulation controls (Rate,
Depth, etc.) affect different aspects of the
modulation in each effect. These are marked
with an asterisk (*) and described for specific
effects in
Effect Descriptions. Other param-
eters, such as the ECHO
÷
controls and
Morph A/B, are described fully in sections of
their own.
Each parameter has a range of control
which is displayed as 1-64. The general
behavior of each parameter is as follows:
MIX
Controls the balance between Vortex effects (the
combination of ECHO FX LVL and MOD FX LVL)
and the dry audio signal. 1=100% dry; 64=100%
wet.
OUTPUT
Controls the output level of the MIX signal.
*MOD FX LVL
Controls the level of the modulation portion of an
effect. 1=off.
*ECHO FX LVL
Controls the level of the echo portion of an effect.
1=off.
MORPH A/B
Controls the rate of morphing between A and B
effects. 1=10 seconds; 64=.01 second. See
Audio
Morphing.™
*ENVELOPE
All Vortex effects are dynamically sensitive. EN-
VELOPE controls the amount of sensitivity applied
to the effect. 1=off; 64=maximum sensitivity.
Note: When both inputs are used, ENVELOPE is
derived from the left input.
ECHO 1
÷
and ECHO 2
÷
Vortex has two delay lines dedicated to echo
effects. The ECHO
÷
controls allow selection of
rhythmic divisions of the tempo you've set. See
TAP and ECHO Rhythms.
*FEEDBACK 1 and 2
Control feedback to the two delay lines (ECHO 1
and 2). Several configurations of feedback and
cross-feedback are used in the effects.
Vortex has two LFOs which are used to
control different types of modulation (such as
vibrato, rotary, pan, etc.) The RATE,
DEPTH, and RESONANCE controls provide
access to different aspects of the modulation
portion of each effect.
*RATE 1 and 2
Control the speed of the modulation effect.
1=0.1Hz; 64=100Hz. Higher speeds are capable
of producing "ring modulation" effects.
*DEPTH 1 and 2
These controls are generally associated with
RATE 1 and RATE 2, and control the amount of
modulation.
*RESONANCE 1 and 2
Control aspects of the resonance around the
modulation effect, such as level, cross-resonance
level, tuning. etc.
