There are three parameters for each FUN. Inputs a and b can be any control source from the
Control Source list. The control sources you want to combine are the ones youÕll assign as the
values for these parameters.
The Function parameter determines what mathematical function is applied to the two inputs.
When a FUN has been assigned as a control source, the K2vx reads the values of the two control
sources deÞned as Inputs
a and b . It then processes them according to the setting for the
Function parameter, and the resulting value is the FUNÕs output.
Chapter 16 describes each of these functions, and provides a few diagrams to give you a hint of
the immense control (as well as some chaos) that these functions make possible.
The VTRIG Page
The velocity triggers base their operation on the attack velocity of each note you play. To use a
VTRIG, you simply set its velocity level (threshold), then set it to switch on or off when your
attack velocities exceed that threshold. Then assign it as a control source for some other
parameter. TheyÕre handy for triggering ASRs, for example.

PARAMETER RANGE OF VALUES DEFAULT
VEL. TRIGGER LEVEL ppp to fff ppp
VEL. TRIGGER SENSE Normal, Reversed Normal
The velocity triggerÕs level is expressed in terms of the standard dynamic markings of western
musicÑppp, pp, p, mp, mf, f, ff, and fff. The K2vx converts each attack velocity value it receives
into one of these eight levels. When a velocity trigger has been assigned as a control source, the
K2vx compares the velocity triggerÕs level and sense with the attack velocity values it receives.
If the sense is Normal and the attack velocity value is greater than the velocity triggerÕs level,
the trigger switches on. When the velocity triggerÕs sense is reversed, the trigger switches on
when the attack velocities it receives are lower than the velocity triggerÕs level. Keep in mind
that you wonÕt hear the effect of editing the VTRIG page until youÕve assigned a VTRIG as a
control source for some other parameter.
The Function Soft Buttons
The remainder of this chapter describes the soft buttons that perform speciÞc functions, as
opposed to selecting programming pages. The descriptions below are arranged in the order in
which you would see the soft buttons if you pressed the more> button repeatedly. You can
always get to these buttons, regardless of which page is currently selected.
Set Range (SetRng)
The Set Range (SetRng) soft button gives you a quick way to set the lowest and highest notes in
the currently selected layer. Press this button, and the K2vx will prompt you to trigger the note
you want to set as the low note for the layer. Press the Cancel soft button if you change your
