In the example below the function generator becomes a complex LFO through
the use of an "Always End" jump which always forces a jump back to segment 1
from the end of segment 5. Thus the function generator constantly repeats
forming a low frequency oscillator.

FUNCTION GENERATOR DELTA & RANDOM LEVEL
There are 3 additional options in the function generator level screen, Delta Level
(level change), Random, and Random Delta (random change). To access the
Delta Level parameter, turn the level value of a function generator one unit past
+127. The delta (∆) symbol appears in the value field.
Delta Level causes the level to change by the specified amount instead of
going to an absolute level value. If Level 1 was set to +127 and Level 2 was ∆-
027, then the resulting level 2 value would be +100 (127-27=100).
The ∆ Level parameter can be quite useful when looping segments. In the
example below, segment 3 has a level of ∆ -016 and loops back to itself as long as
the key is held. Because the level is a change rather than an absolute amount,
the level decreases by -16 each time the segment loops.
