REAPER.
Cost me $60 more than Sonar, but it was worth it.
I also have Reaper on trial ... will support them eventually ... loved winamp ... and looks like this is as good.
Really like the efficiency, the XP and 32-bit support, as well as the DX plugin support. I dabble in old stuff.
Have a laboratory with plenty of low-spec older XP machines running, think it will be king there. And ej ... it supported my Frontier Alphatrack from the get go. I'm a fan.
