Okey, that sounds great. I did find some of this info myself comparing the two Specs lists and the Pa800 hade a few more pre-installed STS, performence and so on. 16 track on both but 100.000 events on the 600 and 200.000 on the 800. Don't think the 600 has any video interface board. Of course I found other stuff like more complex possibilitys like in edeting. The 800 has "Helicon: Three-part Harmonizer" and have not seen anything about any helicon on the 600. Don't know what this means..
