Purchase, Installation and Download


AutoTheory is not a plug in.  It functions outside of your DAW.  It receives input from your midi controller, and sends 8 virtual midi controllers into your DAW.  Within your DAW, you activate and assign them to instruments exactly as you would with regular midi controllers.  You can also sync AutoTheory's Sequencer to your DAW's Sequencer.
