What is Mix Rider?
Mix Rider is an Android application functioning as a MIDI remote control for professional DJ software such as Mixxx (currently only Mixxx is supported).
This app will not play music files directly. A USB cable connection from your Android device to a computer with the Mixxx software package installed is required to start DJing using this app.
Mix Rider works well with house, disco, trance or techno style DJing with a focus on tactile responsiveness and manual beatmatching capability.
