Set the Sampler LFO rate
LFOs, particularly when you use them monophonically, are well suited for creating rhythmic
modulation effects—effects that retain perfect synchronicity even during project tempo
changes. You will find that the triangle waveform is most suitable for adding vibrato to a
sound, and when using an LFO as a modulation source for other LFOs. You are, of course,
free to use any LFO waveform. See Sampler LFO waveforms.
Use the Rate parameter to set the respective LFO to run freely at any speed, or
synchronized with the project tempo when the Sync button is enabled.
Set a free LFO rate
In Logic Pro Sampler, click the Modulators button in the Navigation bar to view the
Modulators pane.
• In the LFO you want to use, make sure the Sync button is turned off, then drag the Rate
field vertically or the Waveform display horizontally to set a value.
The rate is displayed in hertz.
Synchronize the LFO rate with the Logic Pro tempo
• In the LFO you want to use, make sure the Sync button is turned on, then drag the Rate
field vertically or the Waveform display horizontally to set a value.
The rate is displayed in rhythmic values. Synchronized rates range from speeds of
1/128th triplets to a periodic duration of 32 bars. Punctuated values are also available.
Use Sampler envelopes
You can use up to five of Sampler’s identical envelope generators per voice. These
envelopes are shown in the Modulators pane and are available as targets and sources in
the Mod Matrix pane. For details on the roots of the term envelope generator and its basic
function, see Amplifier envelope overview.
ENV1 is hard-wired to Amplitude and defines changes in level over time—for each note
that you play. You can also use ENV 1 as a source for other modulation targets in the Mod
Matrix pane.
Envelope time parameters—Attack, Decay, Release, and so on—are also available as
modulation targets in the Mod Matrix pane. See Sampler modulation targets.
