that's the thing U have 2 have all your audio files converted 2 96KHz.
Then U can have a project at 96khz.
What u doing is a bit like playing a 33.3 rpm record and then changing the speed of the deck 2 78rpm!

PS - U won't hear any difference if u "upsample", it's a bit like having a black and white foto and then seeing that foto on a colour TV, .. U'll b able 2 see it no prob, but it will still b black and white.

Increasing the sample rate 2 something already recorded with an inferior sample rate won't add any quality at all!

PS - Anyways U won't notice any difference between 96 and 48.. it ain't humanly possible. If u do notice any differences it will b due 2 the extra heavy processing necessary!
