Resampling Entire Projects from 44.1 to 48kHz In PT11 speeds up during playback.

Hi all I am trying to determine the best way to re-sample my projects to 48kHz. Now why in the hell would i want to do that? The answer is that my new console is hard set at that rate for USB playback from my DAW. I recently replaced my TAC Scorpion +2 Audiofire 12s with a new A&H QU-32. It really is a wonderful board and I love it greatly enough to live with the silly decision of their hard coding the sample rate for that at 48kHz (and USB2.0 the idiots). I converted an entire session I wanted to rework and remix and the whole thing sounded fast during playback with a slight alvin and the chipmunks kinda vibe. It was really weird. If I just import current wav files from the tracks and re-sample during the conversion to the session rate there are no issues. However doing this I lose all the data and settings that were in the original mix for the track which I want to retain so I can manipulate and modify. Not to mention I dont want to have to spend all day nudging things into place. Has anyone else had an issue with converting entire sessions and it speeding up? Kinda sounds like a software bug. Newer sessions are fine but if I work with others over drop box it seems most folks work at 44.1 so this is going to be an ongoing issue working with collaborators. Help! :confused:



BTW I'm not super savvy on the ProTools 11 as I am still learning the ins and outs and tweaks so please forgive if something I say sounds silly or just plain wrong. Im working through ProTools ignite but an old brain can only retain so much so fast... Peter
