Can someone go into some detail about the arpeggiator on the XV? All I read is "Advanced Arpeggiator"...as if that means anything. I've seen there are something like 48 programs...can you sequence your own? The EX5R gives you a 4 track sequencer for the arpeggiator and the Triton's dual channel arp is really fun to play with. Both of these support multiple ON/OFF styles (latch, hold, etc...)
