ES2 LFOs
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 will
not be 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 precongured 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 eects that retain perfect synchronicity, even during project
tempo changes.
LFO parameters
•
LFO 1 EG slider: Move to 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 the LFO 1 envelope
generator o.
•
LFO 1 Rate slider: Move to 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 ES2 LFO waveforms on page 65.
•
LFO 2 Rate slider: Move to set the frequency of LFO 2 modulation. LFO 2 can be synchronized
with the host application tempo.
