Logic Pro 9: Compressor Circuit Types
Today we will talk about probably one of the best software plugins, that Apple had generously bundled with a Logic Pro 9 software, Compressor. It is one of those plugins that can easily destroy your sound, or if used with precaution, deliver you that unique character.
The main secret that can differ this plugin from hundreds of others are six egos, represented by emulations of different types of hardware, that can be selected in “Circuit Emulation” drop menu. And since there are no official description of those emulations, let’s talk about them.
or Logic Audio Platinum digital compressor.

As example I chose acoustic drums loop, and used same Attack (60ms) / Release (150ms) parameters for all examples. The only thing that I changed during experiment is “Circuit Type”.
In some cases the beat may sound chopped, but for demonstration propose it is okey
As conclusion I have only one thing to say, experiment! Try all different types and combinations of compression on different inputs, and use your creativity.
