Inv button: Invert the effect of the Via modulation source. A negative value becomes positive, and vice versa.
The following tasks apply to all modulation routings.
In the Logic Pro Sampler Mod Matrix pane, click the Plus button (+) at the top right to create a new modulation routing.
Tip: You can Control-click any target parameter in the Synth pane to open a shortcut menu where you can directly add a modulation source. This creates a new modulation routing with the chosen source and target parameters in the Mod Matrix.
Choose the parameter you want to modulate from the Target pop-up menu.
Choose the parameter you want to use as the modulator of the target from the Source pop-up menu.
Note: Sampler will automatically create a corresponding Envelope or LFO if it does not exist in the Modulators pane. For example, choosing LFO 3 from the Source or Target pop-up menu will create LFO 3 in the Modulators pane.
Drag the Amount slider handle to set a fixed modulation intensity.
In the Logic Pro Sampler Mod Matrix pane, click the On/Off button to turn off a modulation routing.
This disables (bypasses) individual modulation routings without losing settings.
In the Logic Pro Sampler Mod Matrix pane, click the modulation routing you want to remove.
Click the Minus button (—) at the top right of the Mod Matrix pane to delete the modulation routing.
This completely removes the routing from the Mod Matrix pane.
The Mod Matrix view filter is useful when setting up new modulation routings and when dealing with complex instrument routings. You can use it to quickly find all routings that use an LFO, Velocity, or other criteria.
In Logic Pro Sampler, click the Filter On/Off button at the top left of the Mod Matrix pane to enable view filtering.
Choose the modulation routing criteria from the Filter pop-up menu at the top left of the Mod Matrix pane.
Only routings which contain Targets or Sources that match the criteria are shown in the Mod Matrix pane.
If you choose the Select last clicked entry, the view filter follows the most recently edited or clicked source or target parameter, and displays routings which use this Source or Target in the Mod Matrix pane.
When the view filter is active, adding a modulation routing automatically adds a Source or Target that matches the current view filter criteria. For example, if the view filter criteria is LFO 1, creation of a new modulation routing will automatically add LFO 1 as a source.
Tip: You can Control-click any target parameter in the Synth pane to open a shortcut menu where you can choose the View Modulation command. This chooses the parameter as the modulation routing criteria from the Filter pop-up menu and turns on the view filter in the Mod Matrix pane.
