What is the Mackie Master Fader 5.2 app?

It's the world's most powerful wireless audio control app for professional live sound applications. It's a new way to mix your music in the studio, on stage, in the hall, or wherever you want. You can mix any type of music, from instruments, to vocals, to drums, bass, and more.

The app allows you to control your music using only your mobile device. It's the same app that is used in the Mackie DL series of mixers. It lets you mix and create music in the same way as you would with a hardware mixer.
