Chapter 7: Preset Programming 79
PRESET PROGRAMMING
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.
FUNC GEN F1S1
Level ∆-127
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.
