Change tuning A = 432hz or C = 528Hz

Hello, I have recently seen in many forums and websites that some people is changing the default tuning of their instruments. Instead of using a tuning of A = 440Hz as is standard, they are using tunings like A = 432Hz or A = 444Hz. I would like to try out if there is any real difference on how the music sounds and feels to the listener.



I do not know how to change the tuning in Pro Tools. May be it is a setting to define in Pro Tools options, or is it a setting to change on each individual virtual instrument? Normally I use Xpand and Vacuum synth. If anybody knows a virtual instrument that allows to change the tuning it is also good news to me. Thank in advance.
