LFO parameters
Double-click a parameter value field to enter a new value. Press Return to complete the
operation.
Minus button (—): Highlight the modulator you want to remove, then click the button to
delete the modulator from the Modulators pane.
+ LFO button: Add an LFO to the Modulators pane. Up to four LFOs can be used.
Waveform pop-up menu: Choose the LFO waveform. For details about how to use them,
see Sampler LFO waveforms.
Sync button: Turn on to synchronize the LFO with the project tempo. The note icon is
illuminated when active.
Rate field: Use to set the frequency, or speed, of LFOmodulation. The value is shown in
note values when the Sync button is active. See Set the Sampler LFO rate.
Fade field: Use to set the time it takes for LFO modulation to fade in or fade out,
depending on which Fade button is active. See Use the Sampler LFO ramp generator.
Fade In or Fade Out button: Click to set an LFO fade-in or fade-out. Use the Fade field
to set the fade duration.
Waveform display: Shows the current LFO waveform. Drag horizontally to set the
frequency, or speed, of LFOmodulation.
Phase field: Drag vertically to offset the waveform start point.
Mono or Poly button: Set the LFO to run monophonically or polyphonically. Mono results
in identical modulation of all voices. Poly provides independent modulation of each
voice.
Unipolar or Bipolar button: Run the LFO waveform in one pole (positive) or two pole
(positive and negative) mode.
Key Trigger button: Turn on key sync for the LFO. Each time you play a key, the LFO
waveform is restarted from the start point.
Sampler LFO waveforms
You can use the LFO Waveform pop-up menu to choose different LFO waveforms. The
table outlines how these waveforms can affect your sounds. See Sampler LFO overview.
Tip: Try different waveforms while a modulation routing of Pitch is engaged and running
to better understand how they affect the sound.
Waveform Comments
Sine Well-suited for vibrato effects.
Triangle Well-suited for subtle modulations, particularly on pad, string, and other
sustained sounds.
Sawtooth Well-suited for helicopter and space gun sounds. Intense modulations
of pitch with a bipolar sawtooth wave lead to bubbling sounds. Intense
sawtooth modulations of lowpass filter cutoff and resonance create
rhythmic effects. Interesting results can be generated by changing the
start point of the modulation cycle with the Phase field.
