Using Vector Synthesis - Korg Kronos Operation Manual

Using Vector Synthesis

Vector Synthesis lets you control Program and Effects
parameters by moving the Vector Joystick, by using the
programmable Vector Envelope, or by 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.
Vector Point and X and Y axis values
+127
Y value: +50
Y-Axis 0
–127
X value: –90
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 necessary have to
use them both at the same time.

Detailed Program Editing Using Vector Synthesis
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.
When the Vector Envelope is in use, the Vector Joystick
offsets the position by up to halfway across either axis.
For instance, if the Envelope is all the way to the right
of the X axis, and the Joystick is all the way to the left,
the actual Vector position will be in the center of the X
axis.
Hint: to quickly reset the Vector Joystick to its center
value, hold down the front‐panel Control Reset button
and move the joystick.
Vector 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 Combi
mode), and it can generate CCs for controlling
Program and Effects parameters.
Vector and MIDI
The Vector features interact with MIDI in two different
ways: through the Vector Joystick, and through the
Vector CC Control.
The Vector Joystick sends and receives two MIDI
controllers: one for the X axis, and the other for the Y
axis. In Global mode, you can assign these to any MIDI
CC numbers you like. The defaults are CC#118 for the
X axis, and CC#119 for the Y axis.
The Vector Joystick and its CCs control the Vector
position, in conjunction with the Vector EG.
The Vector CC Control, on the other hand, is generated
by the Vector position. Normally, this will only affect
internal sounds and effects. If you like, however, you
can also enable a Global parameter to send these
generated CCs to external MIDI devices.

Vector Control" on page 46 of the Parameter Guide.
