Actually ANA 2 probably has one of the worst Arp/Seq that I've tested. Not in terms of presentation but operation. For reasons that are beyond me it can only sequence 6 notes from any scale.
In that respect Dune 3 is superior even though Dune 3 operates in a tiny window making it uncomfortable and less intuitive than ANA2.
Parawave's Rapid did the Arp/Seq correctly.
