C Artist 6 is a definite downgrade from CS5.
No batch export
No RoomWorks
No Studio Chorus
32 Instr Trks instead of 100
64 Audio Trks instead of 100
I could go on but these are mandatory needs for me. This “is” a force to go to the full version whether it’s needed or not and as Crevalation mentioned, add the cost and time of converting to W7. I know of no other DAW or major program that doesn’t have backward compatibility at least to Vista. I’m betting SBs motive there is to have a better success rate with all of Cubase’s features and an easier time of determining user problems for the developers. I have no problem staying right where I’m at with CS5 unless I get saddled with V6 incompatibility from an adjoining work partner or client.
