1–5: X-Y Control
X-Y Control is a function used for vector synthesis control.
Vector synthesis is a function that controls the parameters of
programs or effects by using an X-Y envelope that you
configure.
What does Vector mean?
Modulation generally works by moving a single control. like
a knob, 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.
X-Y Point and X and Y axis values
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
knob), each X-Y point has two values: one for X, and one for
Y. See the graphic “X-Y Point and X and Y axis values” for
an example.
You can also use the X-Y control to move its position
automatically over time, as shown below.

X-Y Volume Control and CC Control
The Vector does two main things: it can control the relative
volume of the two Oscillators in PROGRAM mode (or of up
to 16 Programs at once in COMBINATION mode), and it
can generate CCs for controlling Program and Effects
parameters.
Vector and MIDI
The Vector features interact with MIDI through the X-Y CC
Control.
The X-Y CC Control , is generated by the X-Y position.
Normally, this will only affect internal sounds and effects. If
you like, however, you can use a Global parameter to send
these generated CCs to external MIDI devices; for more
information, see “X-Y MIDI Out” on page 651.
1–5a: X-Y Volume Control
X-Y Volume Control lets you adjust the relative volumes of
Oscillators 1 and 2 by moving the X-Y Control from left to
right on the X axis. The Drum Track is not affected.
