3. Select an LFO Rate of 5Hz.
4. Choose the triangular wave as the LFO waveform.
Tip: Chaotic and fast modulations of pitch by an LFO source—with a delayed
Sample&Hold waveform, a high Rate, and short fade-out—are ideal for emulating the attack
phase of brass instruments.
Logic Pro Sculpture Vibrato parameters
One LFO is hard-wired to pitch, for vibrato effects, periodic pitch modulations. You can
adjust the strength of the vibrato effect with the MIDI controller you choose from the Vib
Depth Ctrl pop-up menu, which is in the MIDI Controller Assignment section. See Assign
Logic Pro Sculpture MIDI controllers.
Vibrato parameters
Waveform pop-up menu: Choose the waveform used for vibrato. See Logic Pro
Sculpture LFO waveforms.
Note: There are two special rectangular waves, Rectangle unipolar (shown as Rect01
when active) and Rectangle bipolar (Rect11 when active)—the former switching between
values of 0.0 and 1.0, and the latter switching between values of −1.0 and +1.0.
Curve knob: Change the shape of modulation waveforms. Such variations can result in
subtle or drastic changes to your modulation waveforms.
Note: The waveform displayed between the Curve knob and the Waveform menu shows
the results of these two parameter settings.
Phase knob: Choose between strictly monophonic or polyphonic vibrato with
variable phase relationships. These can be similar phases, completely random phase
relationships, key-synced phases—or any value in between. For more details, see Logic
Pro Sculpture LFO overview.
Rate knob and field: Set the rate of vibrato, which can be either synced to the host
application tempo or set independently in Hz values.
Sync/Free buttons: Select either a synchronized or free-running vibrato rate. These
buttons interact with the Rate knob. The synchronized value is derived from the Logic
Pro tempo and meter.
