To access the Random Delta parameter, turn the level value of a function
generator one unit past r +127. The random delta (r
∆
) symbol appears in the
value field.

A Random Delta level allows the function generator to change by a random
amount which does not exceed the random change specified. If a random delta
of +16 were programmed, the level could change by any value between 0 and
+16. If a value of -16 were programmed, the level could change by any value
between 0 and -16.

Control
In the example above, the random delta values are set to +16 and -16 and
segment 2 always loops back to segment 1. Note that the level may exceed the
values of
±
16 as long as the amount of change in one segment does not exceed
these values. The example above shows a smooth random generator whose rate
of change is limited to
±
16.
FREE-RUNNING FUNCTION GENERATOR
Hyperpresets contain a slightly different version of the function generator called
a Free-Running Function Generator or Free-Run FG. The Free-Run FG is only
active when a Hyperpreset is in use, even though its destination is programmed
in the preset itself. The Free-Run FG differs from the other FGs in two funda-
mental ways.
There is one Free-Run FG per Hyperpreset which can modulate any presets in
the Hyperpreset which have the Free-Run FG assigned. This differs from the 2
function generators in the preset which are completely independent from note
to note. Because the Free-Run FG is like a global modulation source, it can be
used when you want to modulate multiple sounds in the same way.
