Good job AJ.
The only thing I would like to mention is that you state that the Korg PA80 didn't have a sequencer in earlier versions of the software and they have always had both a backing sequencer and a song 16 track sequencer. Also, I think it is important to know that in Version 3.0 which is coming out in about a week or two will also include a sampler with up to 64 MB of memory from a flash card.
You gave us a lot of information. Thank You,
