I bought the new Masters TDM HD bundle with my protools HD system and it's useless at sample rates above 48k! NO TDM Support. RTAS works for $*^t on a g4/533. It is useless. It does sound good at 44.1k but it's useless otherwise. I complained to WAVES and they offered me a discount for upgrading to a gold bundle... but of course I can't get my money back since I already installed it. It's a useless plugin for HD systems at HD sampling rates ... be warned! I learned my lesson... read the specs carefully before buying and don't trust WAVES.
