Showing syncing and jamming over verse and chorus

Hello friends , just made a video for another forum showing that you don’t have to stay in the same key from start to finish in a song , these people didn’t believe that you could actually have different keys in a song and call them up at will , so i thought I would post it here seeing that I’m new to looping and playing with the BB , great forum by the way , The Boomerang and the Beat Buddy synced up first try without any problem at all , best regards Murray
