from synthesizer wiki on the Internet: Arpeggiator
an arpeggiator is often a built in device in synthesizers, it will listen to the keys you play (chords). when you play a chord it will play (depending on the settings "up" ,"down" , "up/down") each of the played note beginning with the lowest one, after that it will play the next.. if it is set to down ot will of course play the highest note first. if it is in random mode (thats something old Roland ARP'ers offer) ANY of the held notes will be played! so it is "random" but it will of course only play one of those you played as a chord!
