Filter Types

The Filter Type menu allows you to select the Filter algorithm to be used in FILTER 1 or FILTER 2. Omnisphere comes with a wide range of Filter Types. Each of the two stereo filters has the same 70 Filter Types available.

Because of the flexible Dual-Filter system in Omnisphere, different Filter Types can be combined or routed in series or parallel, allowing for hundreds of possible configurations.

The extent to which the frequencies are removed is based on the rolloff slope (measured in dB) of the Filter Type. This means a Lowpass filter with a 24dB rolloff is going to allow less sound to pass than a Filter with a 12dB rolloff.

Once a customized Filter configuration has been created, the settings can be saved as a Filter Preset and loaded from the FILTERS section on the LAYER pages.
