A slightly more complex example could use non-linear segment shapes or
multiple segments in the loop. In the example below, the function generator
decays with a zig-zag pattern when the note is released.
To access the Random parameter, turn the level value of a function generator
one unit past
∆
+127. The random (r) symbol appears in the value field.
FUNC GEN F1S1
Level r-127
A random level allows the function generator to go to a random value which
does not exceed the random level specified. If a random level of +48 were
programmed, the level could go to any value between 0 and +48. If a value of -
48 were programmed, the level could go to any value between 0 and -48. The
random level parameter then, is a limit on the degree of randomness and is
useful for creating smooth, random curves. Smooth random curves can be used
synthesize natural sounds by slightly changing the timbre of a sound in a non-
consistent manner. In the example below, the function generator will follow a
random course within the limits of
±
48.
