Low Frequency Oscillators (LFOs)
Sync
The Sync field specifies whether the LFO is synchronized to a key stroke or
is Free Running. Key Sync starts the LFO wave at the beginning of its cycle
each time you press a key on the controller. In Free Run mode, the LFO
wave begins at a random point in its cycle each time you press a key on the
controller.
Rate
The Rate field determines the LFO speed in absolute frequency rate values
or tempo-based note values. All values equal to or greater than zero specify
absolute frequency values from 0.08 Hz to 18.14 Hz.
LFO Tricks & Tips
:
• The Random LFO wave is truly
random and is different for
each voice and layer.
• The Pattern (Pat) waveforms
will sound the same on
different layers and voices.
• Sine + Noise is very useful for
simulating trumpet and flute
vibrato.

When routing Hemi-quaver
to Pitch:
+38 = major scale
-38 = phrygian scale
+76 = whole tone scale
(+38) + (+76) = diminished
(two cords)
odd amount = S+H sound
Note:
References to musical
intervals in the pattern LFO
shapes are with the LFO
routed to pitch and a
PatchCord amount of +38
