The LFO Page
LFOs are low‐frequency (i.e., subsonic frequency) oscillators. You'll use the LFO page to define
the behavior of the two LFOs available to each layer. LFOs are periodic (repeating) control
sources. The basic elements are the rate and shape, which define how frequently the LFO
repeats, and the waveform of the modulation signal it generates.
With the PC3K, you can set upper and lower limits on each LFO's rate, and assign a control
source to change the LFO's rate in realtime, if you wish.
Because of its periodic nature, the LFO is perfect for creating effects like vibrato (cyclic variation
in pitch) and tremolo (cyclic variation in amplitude). When you're editing LFOs, or any control
source, remember that it must be assigned to control some parameter before you'll hear the
effects of your edits.
LFO1 is always local, meaning that it's triggered with each Note On event, and runs
independently for each note in the layer. LFO2 is local by default, but can be made global. This is
done on the COMMON page, by setting the Globals parameter to On, which causes LFO2,
ASR2, FUN2 and FUN4 all to become global. Global controls uniformly affect every note in each
layer.
