After seeing Marco Carola this weekend at his own festival i'm trying to work out how he play's. For instance he is playing on channel 1 and has a new song coming in on 2. He uses the F1 as a soundbite sending it to channel 3 & 4. He triggers a 2 or 4 beat loop and brings down channel 1 and replaces it with channel 3 with the loop now playing. How come he doesn't just trigger a loop on the song playing on channel 1.
