UAD Powered Plug-Ins Manual - 350 - Chapter 38: Moog Multimode Filter
LFO The LFO (low frequency oscillator) modulates the filter cutoff frequency. Sev-
eral waveform shapes are available. The LFO can be synchronized to the
tempo of the host (see Free/Sync below).
Amount Amount controls the depth of the LFO filter cutoff modulation. A higher value
will have a broader filter sweep.
Rate Rate controls the speed of the LFO. The available range is from 0.03Hz to
25Hz in Free mode, or 16/1 to 1/64 to in Sync mode.
Rate LED The LFO Rate LED illuminates in conjunction with the LFO rate, once per
LFO cycle. Clicking this LED resets the LFO cycle (see “LFO Reset”
below).
LFO Reset The LFO is reset to its zero crossing by clicking the LFO Rate LED. This param-
eter can be automated for mixing or bouncing.
Normally the LFO is “free running” but this behavior is not always desirable.
For example, if you are using LFO filter modulation, you may want playback
to always sound exactly the same when bouncing or mixing. To accomplish
this, the LFO must be started at the same place (zero crossing) of the LFO
waveform. Reset enables this sonic consistency when using the LFO.
Free/Sync This switch defines whether the LFO is synchronized to the tempo of the host
application (if this feature is supported by the host). See Chapter 8, “Tempo
Sync” for more information.
To ensure the LFO phase is consistent when in Sync mode, automate the Reset
parameter (see “LFO Reset” on page 350).
Value The Value display depends upon the setting of the
Free/Sync switch. Value displays the LFO frequency in Free
mode, and the tempo sync note value in Sync mode. See
“Available Note Values” on page 84 for more information.
Wave This control determines the waveform shape used by the LFO. Six waveshapes
are available: Sine, Triangle, Sawtooth-Up, Sawtooth-Down, Square, and
Random.
Offset Offset adjusts the polarity between LFO signals for the left and right channels.
The available range is ±180 degrees.
