Along with the basic controls of inverting values and applying basic math equations, number FX chains can used to adjust the values of data-sources before they are applied to sliders. In this example the 'Fall' FX will be applied to an audio analysis level to create a falling style before being applied to a VU meter generator.
This tutorial begins from having a layer loaded with a VU meter ISF generator along with audio analysis, control surface and preview window plugins.
The setup is accomplished in a few steps:
- Right+click on slider in the control surface and select 'Filter 2' from the list of Audio Analysis data-sources (the 'clap' region)
- From the UI Inspector, click the 'Edit Num FX Chain' button to reveal the number FX chain for the receiver
- Add the 'Fall' FX to the receiver and adjust the value to the desired fall rate
- Click the 'Close' button to close the inspector
- Control+drag from the slider in the Control Surface to the 'audioLevel' slider in the Layer Source controls.
Note that number FX chains are available for every data-source receiver for each slider; in this example we used a Control Surface slider as a go between, but this can be directly applied to the 'audioLevel' slider as well.
