In this day and age, there should be no need to even look at that.....I don't want to get into my DAW is better than others, but Protools Dominates the DAW world in a professional environment. Maybe not the typical home studio.....Huge miss, huge miss. I'm far from being alone, a quick google on the subject, lots of folks out there with my opinion.
A bad decision, it really is that simple. I can understand AAX DSP not being an option. Disappointing to say the least....And Yes, I know there are third party plugins that allow AU and VST to be supported in Protools, but I hate work arounds.
