Using Vector Synthesis

Vector Synthesis lets you control Program and Effects
parameters by using the programmable X-Y Envelope set by
X-Y pad on the display.
What does Vector mean?
Modulation generally works by moving a single control. like
a slider, in a straight line. At one end of the control, the
modulation is at its minimum; at the other end, it's at its
maximum.
Vector Synthesis is a little different. It works by moving
around a point on a two-dimensional plane, both left-right
and up-down.
You can think of this point as being positioned on two
different lines at once: a left-right line (the X axis), and an
up-down line (the Y axis).
In other words, instead of just having one value (like a
slider), each X-Y point has two values: one for X, and one
for Y. See the graphic below for an example.

You can also use the X-Y Envelope to move its position
automatically over time, as shown below.
