LFO parameters
•
Waveform pop-up menu: Choose the waveform used for LFO modulation. See Sculpture LFO
waveforms on page 265.
•
Waveform display: Shows the results of changes to the Waveform pop-up menu and Curve
knob parameter settings.
•
Curve knob: Rotate to 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: Rotate to set the rate of LFO modulation. This is either a freely denable 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/Free buttons: Click to choose either synchronized or free-running LFO rates. These buttons
interact with the Rate knob. The synchronized value is derived from the host application
tempo and meter.
•
Envelope knob: Rotate to set the time it takes for the LFO modulation to fade in or fade out.
See Modulate Sculpture LFOs on page 266.
•
Phase knob: Rotate to 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 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.
•
RateMod Source pop-up menu: Choose a modulation source for the LFO Rate parameter.
•
RateMod Amount slider: Move to set the intensity—the amount—of LFO rate modulation.
