Sculpture LFOs in Logic Pro for iPad
Sculpture offers two multiwaveform LFOs. Both can be used either polyphonically, monophonically, or somewhere in between.
If used monophonically, the modulation is identical for all voices. Imagine a scenario where a chord is played on the keyboard. If LFO 2 is used to modulate pitch, for example, the pitch of all voices in the played chord rises and falls synchronously. This is known as a phase-locked modulation.
In the same scenario, if LFO 2 is used polyphonically—to modulate multiple voices—they are not phase-locked.
If a random (in-between) value is used, some notes are modulated synchronously, and others are not modulated synchronously.
Furthermore, both LFOs are key-synced: Each time you play a key, the LFO modulation of this voice is started from 0.
To understand the non-phase-locked characteristic more easily, imagine a situation where a chord is played on the keyboard. If LFO 2 is used to modulate pitch, for example, the pitch of one voice might rise, the pitch of another voice might fall, and the pitch of a third voice might reach its minimum value. As you can see from this example, the modulation is independent for each voice, or note.
The key sync feature ensures that the LFO waveform cycle always starts from 0, 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.
Both LFOs can also be faded in or out automatically, courtesy of built-in envelope generators. See Modulate Sculpture LFOs.
Tap the Modulation button at the top of the plug-in to view and adjust the Sculpture LFO parameters.
LFO parameters
Waveform pop-up menu: Choose the waveform used for LFO modulation. See Sculpture LFO waveforms.
Curve knob and field: Change the shape of modulation waveforms. A pure waveform of the chosen type is active at a value of 0.0. The +1 and −1 positions deform the wave. For example, with a sine wave chosen as the LFO waveform type:
Curve value of 0.0: Wave is sine-shaped.
Curve values above 0.0: Wave is smoothly changed into a nearly rectangular wave.
Curve values below 0.0: The slope at the zero crossing is reduced, resulting in shorter soft pulses to +1 and −1.
Rate knob and field: Set the rate of LFO modulation. This is either a freely definable Hz value (when the Free button is active), or a rhythmic value (when the Sync button is active). When synchronized with the project tempo, available rates range from 1/64 notes to a periodic duration of 32 bars. Triplet and punctuated values are also accessible.
Sync Mode buttons: Choose either free-running (Free) or synchronized (Sync) LFO rates. These buttons interact with the Rate knob. The synchronized value is derived from the Logic Pro tempo and meter.
Phase Vari knob and field: Choose between monophonic or polyphonic LFO modulations. These can have similar phases, completely random phase relationships, key-synced phases, or anything in between.
Tip: If you move the Phase Vari(ation) knob slightly away from the mono position, you get nonlocked modulations for all voices running at similar, but not identical, phases. This is ideal for string-section vibratos.
RateAmt knob and field: Set the intensity—the amount—of LFO rate modulation.
Rate Mod Src pop-up menu: Choose a modulation source for the LFO Rate parameter.
EG Delay slider and field: Use the envelope generator to set the time it takes for the LFO modulation to speed up to its modulation rate or slow to no modulation. See Modulate Sculpture LFOs.
