FUNS
The FUN Equations
16-6
| a - b |
The value of input b is subtracted from the value of input a, and the absolute value is taken. If
the difference is negative, it is multiplied by -1. This also makes the FUN unipolar.
min (a, b)
The values of inputs a and b are compared, and the smaller value becomes the output value.
This can be used to limit the value range of a control source. If, for example the value of the
control source assigned to input b is left at +.5, then when the value of the control source
assigned to input a is between -1 and +.5, its value will be used. As soon as its value exceeds
+.5, the value of input b is used.
max (a, b)
This is the opposite of the previous equation. The values of inputs a and b are compared, and
the larger value becomes the output value.
Quantize b to a
This turns the control source assigned to input b into a stepped control source. Instead of
smooth transitions from minimum to maximum, it will jump from minimum to maximum in
some number of equal steps. The number of steps is determined by the value of input a. The
normal realtime application of this is to set a stationary value for input a to set the number of
steps in the effect. Then use the control source assigned to input b as a realtime control to
induce the stepped effect. Changing the value of input a in realtime will produce an extraneous
(but possibly useful) effect.
