What Avid should do though to bridge the time until we get a 64-bit version (and I put this up on the ideascale site as well) is to allow third party Rompler and Sample plugins, that support disk streaming, to stream the samples from the new RAM disk Cache in PT 10.
This will allow those plugins to read and write their samples from and to the RAM cache and sort of ditch the memory limitation until they come up with a full 64-bit version of Pro Tools. This will keep the user base happy AND give them time to develop the ultimate 64-bit pro tools version without being harrassed every odd minute.
Would be a cool feature
Maybe in version 10.1?
