Step/Track
This switch is a smoothing control for the filter cutoff frequency parameter.
Smoothing is most obvious on continuous filter sweeps when varying the cut-
off rapidly with the knob or automation. Step mode can be desirable when
sudden cutoff changes are automated and other creative purposes.
Smoothing is on in the Track position, and off in the Step position.
Note:
quency like a synthesizer filter.
Mode
This control is the heart of the Moog Multimode filter, combining Moog's clas-
sic lowpass filter with highpass and bandpass in one control. Unlike Moog
highpass and bandpass filters of the past, UA's design presents Moog's sig-
nature self-oscillation in all three modes, bringing a new level of sophistica-
tion to Moog filter designs of the past. The knob switches between the avail-
able filter types.
Lowpass
Bandpass
Highpass
Spacing
Spacing inversely offsets the filter cutoff values for the left and right channels.
In other words, positive Spacing values increase the right channel cutoff while
lowering the left channel cutoff, and vice versa.
Spacing is borrowed from Bob Moog's Voyager instrument, and separates
the hard-panned filters by up to three octaves. Unlike the original however,
both filters are moving away from each other in pitch, rather than one fixed
filter plus one adjustable filter pitch. Positive or negative values enable posi-
tioning the de-tuned filters from left to right, low to high, or high to low.
Spacing can create great stereo spacial effects. When the filter is in Mono
mode, both filters are still heard.

UAD Powered Plug-Ins Manual
When set to Track, the plug-in does not "track" the input signal fre-
Frequencies above the cutoff value are filtered.
Frequencies above and below the cutoff value are filtered.
Frequencies below the cutoff value are filtered.
Click the knob label ("SPACING") to return the value to zero.
