AutoTheory 4 is an incredible plugin that allows any one to play chords and melodies like a professional. You keep your attention on your rhythm and AutoTheory will keep you in key!
Joshua Casper shows you around this awesome plugin that helps you with your music theory. In fact, it takes care of the music theory completely and just lets you focus on your playing instead of what you’re playing. Using only the white keys of the keyboard you can make magnificent and complex chord progressions and accompanying melodies. The black keys of your MIDI keybaord are transformed into hot swap keys for changing scales and triggering arpeggios.
