Since each mixer track in the FL Studio Mixer can have its own chain of effects, there are ways to save your work and develop your own templates over time. FL Studio also has some defaults to get you going and improve your understanding of certain mixer chains. Remember that each mixer slot can have its own chain from 1 to 8 in the vertical list.
To get started with using your mixer to the best of your abilities, you simply need to have audio enabled on any of the mixer tracks. This was reviewed in the Sending a channel to a mixer slot recipe in Chapter 3, Working with Step Sequencer and Channels. You can press F9 to bring up the FL Studio Mixer.
