I've been using final scratch off and on for about half a year now, all i got to say is that its decent, not great. The technology simply doesn't do well on long mixes, the latency sucks, the scratch amp is a piece of crap, there is a new version of the software coming out in a week that is supposed to fix the install problems since it actually runs on WinXP /NTFS and not a linux port on its own partition. Anyway, doesn't A-sides have a stanton endorsement or something? I just wish Stanton/NI would get their shit together.
This will be a tight show for sure though, Josh Wink seemed to have great sets with it.. It will be interesting to listen to A-Sides mixes!
What will be intersting is to see how many people will drop Stanton as soon as the RANE final scratch like product comes out, just from the pictures it looks like at least the hardware is decently made ->
