LFO Modulation
The Velocity Sensitivity controls determine how much the
velocity affects the pitch of the sound (Pitch), the attack of
the filter envelope (Attack), the volume level of the sound
(Amp), and the panning of the sound (Pan).
When you press a pad softly, only minimal modulation is
applied. When you press it harder, the modulation amount
also gets stronger depending on the setting of the
corresponding knob.
A low-frequency oscillator (LFO) generates a periodic
waveform with an adjustable frequency and shape which
can be used for modulation purposes.
Use the Wave field to select the LFO waveform type:
Sine (best suited for smooth modulations)
Triangle (best suited for smooth modulations)
S&H (samples a random value and holds it until the next value is generated)
Saw (can generate interesting filter or volume changes)
Saw Down (can generate interesting filter or volume changes)
Square (interesting results with hard-panning modulations)
Noise (generates random values and glides)
Use the Rate field to determine the LFO frequency when Sync is on. 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.
