Here is a simplified demonstration:
The BBPlugin is playing back the Pedal Steel wav in SavedTracks,
why not play it back direct from the RT folder and only render it together to a new file if it needs to be dragged out ?
Why spend all that time to render to RAM then render to wav a new file to fill up the hard drive ?
Any transposition or playback rate adjustment will be applied with dllelastiquePro3.dll in realtime.




This 2005 32bit VST has no problem, look at the different sections of RT RD source files it's playing:
