"FUN" is short for "function." The K2500's four FUNs greatly extend the flexibility of the
control sources. Each FUN accepts input from any two control sources, performs a selectable
function on the two input signals, and sends the result as its output, which can be assigned like
any other control source. Using the FUNs involves defining them on the FUN page, then
assigning one or more of them as control sources. The FUN page looks like this:

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 you'll 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 K2500 reads the values of the two
control sources defined as Inputs a and b. It then processes them according to the setting for the
Function parameter, and the resulting value is the FUN's 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.
