Logic Pro X Compressor: A New Model and a Makeover

Logic Pro X's Dynamics Compressor plug-in got more than a visual makeover in version 10.1. We'd go as far to say it's been born again. Joe Albano covers the new model and other new things.  

Among the many new features introduced in the Logic 10.1 update to Logic Pro X, the included Compressor plug-in was born again, with a new face (faces, actually), and a new model joining the the emulations of classic compressor circuit types included in the previous plain-jane version.

There were also some reports that, despite this fact, people were finding that some tracks that had been mixed with the original version sounded a little different. Eventually, Apple addressed this in the 10.1.1 update, which notes a fix to an occasional bug that might cause the emulated behavior of the detection circuit (peak or RMS)'"an option not available in all the compressor models'"to be changed in models that didn't have the feature, based on the last settings on the (one) model that does (the generic legacy 'Platinum Digital'
