How did the producer make this work? @@
Would be sick to get a setup going where I can jam with a program that plays along with me when writing

wtf?

i think he has either some midi output thing on the guitar and is controlling ableton(or something), or has some sound recognition program in his guitar output and its playing some drum track all the time it hears guitar.
