The very reason I use REAPER now is it does not drain your wallet each new release while REAPER has extensive features that Pro Tools still does not fully possess.
and...
AVID/Pro Tools is one of the few that **NEVER** allows "free trial" of anything, and even then, it probably would only work on a very specific PC or MAC build, as that's the other thorn in my side about AVID is they will not even give you support if they determine you have a PC/MAC that "has not been fully and properly tested AND **approved** by AVID!
Eeeek!!!
FWIW-the completely FULL version of Reaper with absolutely no limitations nor "Light Edition" is freely downloadable for your trial and then for a non-commercial license of $60. USD that's completely on the honor system, you have a powerful DAW with free updates for a long period. Then you can download additional features that integrate seamlessly into Reaper from Standingwaterstudios, the "SWS Extensions", as they are called, developed in partnership for Reaper. Just a more sane DAW and company and is actually quite light on the CPU side for all its power and yes...it is for both PC and MAC and other virtual instrument formats are compatable....oh, you do not need a freaking Dongle as Pro Tools does and that recent nightmare people went through earlier this year!!
Hope this helps and know not answer you wanted to hear!
