FILTER ZOOM in Omnisphere provides precise control over each Layer’s dual-filter. The two stereo filters are represented on the right and left. The central area controls the routing and contains the shared controls. Each of the two stereo filters can have any of 32 filter types assigned to it. They can be combined in series or parallel, allowing for hundreds of possible filter configurations.
There are primary Cutoff, Resonance and Variant controls for the entire filter, but both FILTER 1 and FILTER 2 each have their own independent Cutoff, Resonance and Variant offsets which are applied to those primary values.
FILTER SECTION POWER SWITCH
Enables or disables the entire Filter. It is a duplicate of the power button on the EDIT page. The entire Dual-Filter can be turned on and off with this switch, which provides a quick way to compare the sound with and without filtering.
FILTER 1 & FILTER 2 POWER SWITCHES
Enables or disables Filter 1 and/or Filter 2.
NOTE: If both Filter 1 and Filter 2 are turned off, the only control on the Filter Zoom page that will still change the sound is the GAIN slider.
Omnisphere has a wide variety of customized filter configurations, called presets. The presets represent the settings of Omnisphere’s complex dual stereo filter. Filter presets can be selected, copied, pasted and saved from this menu.
TIP: If you find a Patch that has an interesting custom filter configuration, you can save it into your preset library to use with your own patches!
The Presets are categorized into several sub-categories; Bandpass Filters, Highpass Filters, Lowpass Filters and Specialty Filters. For the sake of space, the preset names are abbreviated, but this is what the different abbreviations mean:
|BPF||Band Pass Filter|
|HPF||High Pass Filter|
|LPF||Low Pass Filter|
|UVI||UVI Filter from Atmosphere®|
|db||Short for Decibel. Names like 12db, 24db, refer to the roll off slope of the filters.|
NOTE: Filter presets are not the same as Filter types. Filter presets include the settings for Filter type.
FILTER PRESET MENU
After a Preset has been chosen from the drop-down menu, the name will be displayed in the preset display window:
If the filter types are changed in the Zoom view, then the display will be changed to “Modified” until the Filter settings are saved as a preset or another preset is selected.
NOTE: Filter presets intentionally do not recall CUTOFF, RES, KEY and ENV settings. This is done because it’s the best way to audition the different Filter Presets within the context of your current Patch.
