FUNS
The FUN Equations
16-11
warp2(a, b)
We call this equation Slant-square.
Ô
Again, the value of
input a
controls the mapping of values
for
input b
. If
input b
is a sawtooth wave, different values for
input a
will turn it into a number
of variations on square waves.
warp3(a, b)
We call this one the Variable Inverter.
Ô
It looks at the binary numbers that represent the values
of
inputs a
and
b
, compares the corresponding bits in each number, and performs an XOR
operation on them (weÕll explain that below). The resulting number is converted into the
output value. This can produce some erratic results, but if variety is what youÕre after, this
equation will give it to you. YouÕll get your best results when
input b
is an LFO with a slow
rate.
The XOR operation is a subprogram that applies a truth table to each of the digits in the binary
numbers that represent the values of
inputs a
and
b
. Each of these numbers is a string of 16
digits (bits); each bit is either a 0 or a 1. The subprogram looks at the Þrst bit of each number. If
theyÕre both 0s, the resulting value is 1. If one is a 0 and the other is a 1, the result is 1. If theyÕre
both 1s, the result is 0. This process is repeated for the remaining 15 bits of each number, and a
new 16-bit number is generated. This number represents the output value of the FUN.
