10. Randomness
probability that any value within the range
may be selected. If
Gaussian,
values nearer to
the target level are more likely to be selected
than values nearer the extremes of the range.
Here are the places you can program
randomization:
Initial Level Randomization
When a contour is started or retriggered from
Segment 1, it starts at the level set by the
Start Level
parameters in the
Preset Globals
menu. The
Reset Random Level
and
Reset
Random Shape
parameters allow you to
select an optional amount and distribution of
randomness that varies the
Start Level
each
time the contour is started or retriggered.
Real Time Randomization
As will be described in detail in
Chapter
15,
while a contour is playing, you can
add randomization to the active segments
in real time by pressing the
Randomize
button. The amount and distribution of this
randomization is set by the
Randomize
Level
and
Randomize Shape
parameters in
the
Preset Globals
menu. (Note that these
parameters are separate and independent
from the
Initial Level Randomization
parameters described above.)
Segment Randomization
Each segment can optionally have a
programmed amount of random variation
applied to its programmed
Target Level.
The
randomness parameters are programmed via
the
Randomness Button
and interact with
the
Level Mode
as follows:

Random variations in CV levels can bring
a subtlety organic feeling to a repeating
pattern, as well as allow the creation of
much more dramatic randomized contours.
Control Forge provides three independent
sources of randomization and lets you select
both the range within which randomization
will occur and the probabilistic distribution
of the random results within that range,
independently for each source.
Randomization Range
This
parameter
defines the
symmetrical
range, in
volts, within
which the
programmed
CV Level will
be randomly
modified.
The range of
values is from
+/-0V to +/-5V in 10mV steps. For example, if
you select a randomization range +/-1.5V, the
actual CV will be somewhere between 1.5V
below the programmed CV level and 1.5V
above it.
Randomization Distribution
This
parameter
defines the
distribution
of potential
random
values within
the random-
ization
range. If
Linear,
there
is an equal
