Use the Rate field to determine the LFO frequency. At lower values, it might take some time for the LFO to complete
a cycle, while higher values will come closer to audible range.
Use the Sync field to set if the LFO's rate is synchronized with the tempo. You can select one of several time
divisions (a . indicates a dotted note; a T indicates a triplet-based time division). When None is selected, Sync is off.
Use the Destinations sliders to determine how much the LFO affects the pitch of the sound (Pitch), the cutoff
frequency of the filter (Filter), the volume level of the sound (Amp) and the panning of the sound (Pan).
The Controller Mod section determines the influence of additional play controllers on various sound parameters.
Important: To use these parameters, make sure that a connected MIDI device can send pitch bend messages as
well as aftertouch and modulation wheel data.
Pitch Bend sets the range (in semitones) of a connected MIDI keyboard's pitch-bend wheel.
Wheel>LFO determines how much a connected MIDI keyboard's modulation wheel affects the LFO intensity.
Aft>Filt (Aftertouch Filter Cutoff) determines how much a connected MIDI keyboard's aftertouch data affects the
filter cutoff.
