This chapter serves as an introduction to parameter modulation. Because of the complexity of the topic it is pitched at the relatively experienced user. Parameter modulation takes REAPER’s routing, channel splitting, automation and sidechaining capabilities to new levels. You should probably not attempt this chapter unless you already have a sound grasp of these concepts. If necessary, turn back to the section More Routing Examples and work thru it again. Parameter modulation at its simplest means using the level of a track's volume or one or more FX parameter to control the behavior of one or more other FX parameters on the same track or on a different track or on a number of tracks. One relatively simple example might relate to the application of a chorus plug-in to (say) a guitar or bouzouki track. Suppose that we wish to vary the wet level of the chorus throughout the track so that as the instrument’s volume increases the wet/dry ratio is adjusted . Incidentally, this particular example can create an interesting effect of space and distance on the instrument, but that is not the main point of the exercise. Changes in an effect like chorus are relatively obvious to the human ear. The main point of this exercise is to show you how parameter modulation is set up and used. It’s then up to you to use and apply it in ways that you'll find will bring new life and vigor to your own mixes.
