You probably already have one of the best Pro Tools compressors around — but you might not know it!
It's tempting to view third-party plug-ins as being inherently more desirable than your DAW's stock effects. There are, of course, third-party plug-ins that are absolutely unbeatable, and so there should be. If your job is creating the very best EQ, compressor or reverb, then a company who have the rather bigger task of creating and maintaining a DAW have no business beating you at your own game! However, while there are plenty of very respectable plug-ins in the stock complement which ship with Pro Tools, the definition of exactly what constitutes a 'stock' plug-in has become a little more flexible recently.
The Avid Pro Series plug-ins are a case in point. If you have a current Pro Tools rental subscription or a Pro Tools Ultimate upgrade plan then you get access to the Pro Tools Complete Plug-in Bundle, the highlight of which is, for me, the Pro Series Plug-ins. These are every bit as good as any premium plug-in I've ever used, and if you were to ever pass them by because they are Avid plug-ins and so are in some way less interesting than your third-party plug-ins, you would be doing them and yourself a great disservice.
If you want more reasons to pay attention to the Pro Plug-ins, remember that as 'nearly stock' plug-ins, their availability to anyone with a current Ultimate upgrade plan or Pro Tools subscription means they are by definition more ubiquitous among Pro Tools users than any third-party...
