ES2 LFOs
Logic Pro ES2 LFO overview
ES2 features two multi-waveform LFOs. Both are available as sources in the router.
LFO1 is polyphonic, which means that if used for any modulation of multiple voices, they
are not phase-locked. LFO1 is also key-synced:each time you play a key, LFO1 modulation
of this voice is started from zero.
To understand the non phase-locked characteristic more fully, imagine a scenario where a
chord is played on the keyboard. If LFO1 is used to modulate pitch, for example, the pitch
of one voice may rise, the pitch of another voice might fall, and the pitch of a third voice
may reach its minimum value. As you can see, the modulation is independent for each
voice, or note.
The key-sync feature ensures that the LFO waveform cycle always starts from zero, which
results in consistent modulation of each voice. If the LFO waveform cycles were not
synchronized in this way, individual note modulations would be uneven.
LFO 1 is preconfigured to control the pitch of all three oscillators. It can be
simultaneously used for modulation of other parameters.
LFO1 can also be faded in or out automatically, courtesy of a built-in envelope
generator.
LFO2 is monophonic, which means that the modulation is identical for all voices. For
example, imagine a chord is played on the keyboard. If LFO2 is used to modulate pitch,
the pitch of all voices in the played chord rises and falls synchronously. LFO2 is ideally
suited for creating rhythmic modulation effects that retain perfect synchronicity, even
during project tempo changes.
LFO parameters
LFO1 EG slider and field: Set the time it takes for the LFO modulation to fade in or fade
out. The value is displayed in milliseconds beneath the slider. Click the zero to turn off
the LFO 1 envelope generator.
LFO1 Rate slider and field: Set the frequency (speed) of LFO1 modulation. The value is
displayed in hertz (Hz) beneath the slider.
LFO1 Wave buttons: Choose the waveform used by LFO1. See Logic Pro ES2 LFO
waveforms.
LFO2 Rate slider and field: Set the frequency of LFO2 modulation. LFO 2 can be
synchronized with the Logic Pro tempo.
