Lol! The one limitation of the Pico is (unlike the Tau/Alpha) there is no headphone out, meaning that a metronome or drumbeat is required to keep in time. You do have to choose a loop length of one, two, four, eight bars etc. You are able to remove elements from the loop as you can hear at about 2:50 here http://www.youtube.com/watch?v=uaPlx-7Vqw4&feature=channel, where I switch off the piano and bass, which then return at the end of the song.
