Vector and Vector Envelope
Overview
Vector Synthesis lets you control the sound by moving the Vector Joystick, using the programmable Vector Envelope,
or the combination of the two.
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 Vector point has two values: one for X, and one for
Y. See the graphic below for an example.
To control the Vector manually, you can use the on-screen Vector Joystick or CC #16 (X axis) and CC #17 (Y axis).
If you’re using a controller with a physical Vector Joystick, the range will generally be constrained as shown in the
graphics below.

In addition to moving the point directly with the Vector Joystick, you can also use the Vector Envelope to move its
position automatically over time, as shown below.

Vector Joystick and Vector Envelope
You can move the Vector point using the combination of the Vector Joystick and the Vector Envelope. The two work
together, although you don’t have to use both at the same time.
When the Vector Joystick is in its center position, the Vector Envelope has complete control over the point’s position.
Likewise, when the Vector Envelope is in the center, the Vector Joystick has complete control.
