The central part of the FILTER ZOOM section is dedicated for controls that are common to both of the Filters, including the ability to route to two Filters in parallel or series and to place them before or after the Amplifier.
The CUTOFF, RES, VARIANT, KEY, ENV and GAIN controls are exactly the same as those in the Filter section on the LAYER pages. Any changes that are made on these controls will be reflected on the LAYER page as well, and vice-versa.
When Omnisphere’s two Filters are in “Series”, it means that the output of Filter 1 is feeding into Filter 2 – and thus affects the character of Filter 2. When the two Filters are in Series, the Mix control is not in use. “Parallel“ means the two Filters are both working, but they are not directly affecting the other; they are operating side-by-side and mixed together. The Mix slider controls the balance between the two filters.
In Parallel mode, each of the two Filters pass thru the Filter Mixer, and the Mix control determines how much of each filter is heard. Centering the slider will allow both filters to be heard equally, and sliding it to the right or left will favor one over the other.
Range 100.00 to 00.100 (50.50 is the center point)
The Gain adjusts the level of the input or output of the Filter Module depending on the Pre & Post setting.
Range between – inf (0) and +9.54.dB
PRE & POST
The Dual-Filter can be placed before or after the Gain Control. These switches determine if the gain control will be used before or after the Filter. Aggressive Filter sounds will have a different character depending if PRE or POST is enabled.
The Gain Control is applied before the Filters.
POST means that the Gain Control will be applied after the Filters
