8.3. LFO (Low-Frequency Oscillator)

The LFO is polyphonic, so every voice in the Carrier has its own LFO, controlled by the
parameter values in the LFO section. The LFO provides six waveform shapes, which can
run continuously or be triggered in various ways. The LFO display shows the selected
waveform, and how it's affected by the following controls.

8.3.1. LFO Controls

Waveform Choose the waveform shape from the drop-down menu below the
•
waveform graphic: Sine, triangle, sawtooth, ramp (positive-going sawtooth),
square, and SnH (Sample and Hold, a random output derived from sampling
noise).
Rate (0.001 Hz to 200 Hz, or rhythmic values). The left Rate parameter sets the
•
LFO speed if the Rate parameter on the right is set to Hertz. If the Rate parameter
on the right is not set to Hertz, then Rate chooses one of the following rhythmic
values to sync the rate to tempo: 8, 4, 2, or 1 measure, or 1/2, 1/4, 1/8, 1/16, or 1/
32 notes. Setting the parameter to the right to Binary chooses the preceding note
values. Setting it to Dotted chooses dotted values (i.e., the rhythmic value + half
the rhythmic value), while Triplet chooses triplet values for these notes.
Single Playing a note on the keyboard generates one cycle of the LFO waveform.
•
If Single is selected, Cycle is not available.
Cycle The LFO cycles through its waveform continuously. If Cycle is selected,
•
Single is not available.
Retrig This is available only in Cycle mode. Pressing a key re-triggers the LFO
•
to start at the beginning of its cycle. For example, if the Rate setting is several
measures, you can initiate the LFO's cycle when you hit a key, regardless of the
LFO waveform's current position.
Unipolar When selected, the LFO applies only a positive control signal to the
•
destination. When de-selected, the LFO applies positive and negative control
signals to the destination. Unipolar is useful if you don't want a target parameter
to go below a certain level (e.g., the default level is set low, so you don't want
additional modulation to lower it, only raise it).
The output can route to two destinations. See section 8.4.2 for information on selecting
destinations and assigning modulation sources to them.
