This is from waves... "Q: Do Waves plugins need to be updated only to run at higher sample rates? A: Higher sample rates is the problem, PT HD doubled the sample rate but not the DSP power so any plug in taking more then 50% on your current mix will not work under 96KHZ on the new HD." So no c4 at 96k folks! If I remember correct, the new chips are 20% more powerful. Think about it....BF pultec takes 50% of the mix chips, meaning you will only get ONE MONO INSTANCE PER CHIP on HD at 96k! Same with the Sony eq! Or even take the BF 1176 or LA2A....they take 33% of a mix chip. Since the dsp requirements double at 96/88k then with the only 20% stronger chip, you still only get ONE instance per chip!! Reverbs have the downsampling workaround, thats how they are able to fit on one chip at 96k (coz they are really at 48k internally) If I am wrong in assuming the rest of these plugin forecasts someone please tell me....But the Waves stuff is right from them..."any plug in taking more then 50% on your current mix will not work under 96KHZ on the new HD"...from which one can deduct that many plugins that are close to the 50% mark will only get one instance per chip.
