When a parameter is modulated, the routing is automatically shown in two sections: in the left side of the plugin (replacing the Mini Browser) and in the Layer pages. They both have similar controls, with the advantage that the area on the left of the plugin is visible from other pages (FX, ARP, Zooms, etc).
The Modulation sections display the most recent modulation routing, which can also be edited there. The key concept of the Modulation section is that only one modulation routing is displayed at a time (the Mod Matrix Zoom shows many routings simultaneously).
To display a specific modulation routing, right-click on the target parameter (i.e. Arpeggiator Speed) and select the routing from the “Show Modulation Menu.” The routing will be displayed in the left column of the plugin while the Arpeggiator page is shown. This allows you to make adjustments in the Arpeggiator and in the routing, minimizing the amount of navigation. To close this view and return to the Mini-Browser, click on the magnifying glass icon with the minus (-) sign to the right of the column’s title.
Selecting the drop down arrow on the MODULATION header in the Layer Page will bring up a menu that allows new modulation routings to be created as well as the removal of existing routings. All of the modulation routings set up in the currently selected Layer are visible from this list. Selecting any of these routings will allow them to be displayed and modified in the Modulation section of the Layer Pages.
The SOURCE area displays and selects the modulation source to control a target. Selecting the source will open up a menu of 34 modulation sources and “Off” negates any modulation source.
This slider controls the amount of modulation that will be sent from the source to the modulation target. If the slider is set to minimum, the modulation source will have no effect on the modulation target. The higher the setting, the more the source will affect the target. However it is possible to send too much signal from the source, which causes unusual behavior in the target because the values are out of range.
The TARGET selects (and displays) the destination for the Source’s modulation output. Omnisphere has a large number of modulation targets, including synthesis parameters as well as effects parameters.
The full list of Targets is listed in the MODULATION section here.
This slider is a duplicate of the target parameter – meaning it’s another representation of the parameter that’s being modulated. Inside the parameter ‘slot’ is a dual indicator. The blue line represents the range of the modulation and the white point indicates the current value of the modulation.
The currently displayed modulation routing can be muted with this switch. This is a quick way to A/B the Patch with and without the modulation routing.
The Invert button inverts the modulation polarity.
For example, if the modulation source is an LFO with an ascending ramp wave as its waveform, it will invert the polarity so it results in a descending ramp modulation.
SMOOTH (left column only)
The modulation Smoothing control takes the incoming modulation source and slows the sharper points down, smoothing them out. This means that the character of the modulation source will not have quite as drastic or harsh an effect on the modulation destination. It works in a similar way to the Lag processors on some vintage synthesizers. This is the same principle that is used in Glide/Portamento, but applied to any source and target.
Modulation Source Controls (left column only)
For convenience, the modulation source controls are displayed at the bottom of the left column. For example, if an LFO is selected as a source, the corresponding LFO’s controls will be available here. When sources don’t have controls (Alternate, Random), a representative image will be displayed instead.
