Omnisphere’s MASTER FILTER controls the entire Patch, meaning that it affects all Layers. The MASTER FILTER is separate from Omnisphere’s dedicated Filter section on the LAYERS page and is designed as a simple tone control. The extensive Filter section in the LAYER pages should be used for more serious and surgical sound-shaping.
TYPE (LPF / HPF)
The MASTER FILTER has two available filter modes; LPF and HPF. The HPF (Highpass Filter) removes low frequencies from the sound, allowing high frequencies to “pass.” The LPF (Lowpass Filter) removes high frequencies from the sound, allowing low frequencies to “pass.”
NOTE: LPF or HPF are exclusive and cannot be enabled simultaneously.
CUTOFF
The primary function of the filter CUTOFF is to remove, hence “cut off,” frequencies from the sound. Depending on which Filter Type is chosen, the Cutoff control will remove different frequencies in various ways. If a Lowpass Filter is used, moving the slider to the left will remove the higher frequencies. If a Highpass Filter is used, the opposite will occur.
As you move the slider, the frequency will be displayed.
Range: 0.050 kHz ~ 19.000 kHz
Right-click and select “Enter Parameter Value” to type in a numerical value.
RESONANCE
The RESONANCE slider controls the entire Patch, meaning it affects all Layers. RESONANCE (sometimes called “Q”) adds emphasis to the cutoff point of the MASTER FILTER. Because it works with the MASTER FILTER, it will have no effect on the sound if the MASTER FILTER is set to minimum value.
At minimum settings, little or no resonance will be heard. Moving the slider to the right will add more resonance to the sound.
As you move the slider, the numerical Q value will be displayed.
Range: 0.000 ~ 1.000
Right-click and select “Enter Parameter Value” to type in a numerical value.
NOTE: The Master Filter is not capable of self-oscillation, but the Dual-Filter on the LAYER page is.
