The Bomb Factory Purple Audio MC77 compressor plug-in was easy to install and the process was a pretty quick one. I had no compatibility issues with my machine and overall it runs smoothly without any issues. The interface of the plug-in is identical to the Purple Audio MC77 hardware unit, as well as Universal Audio's classic 1176 compressor. It has four knobs - one for input, one for output, one for attack, and one for release. It then has buttons to choose the ratio of the compression and also has options for metering. I don't have a manual for this so I can't speak to how helpful it is or not.

SUITABILITY/PERFORMANCE

I am running the Bomb Factory Purple Audio MC77 on a Mac Book Pro that has a 2.2 Ghz Intel Core 2 Duo processor and 4 GB of RAM. I run the plug-in Pro Tools LE 7.4 with a Digi 002R audio interface. I have never had any problems with running this plug-in with this configuration, as I am able to run four or five of these at once if I wanted to. Overall, the MC77 is stable with my configuration.

OVERALL OPINION

I have been using the Bomb Factory Purple Audio MC77 for around two years. While I have found it quite useful, it isn't one my favorite compressor plug-ins out there. The sound quality is good and is great on drums, but it isn't the most versatile plug-in out there as it has a somewhat limited use in terms of what instruments it sounds good with. The price is reasonable if you can find it within a bundle, but is overpriced otherwise in my opinion. I would rather have a URS 1970 Classic Compressor or Digidesign Smack over this in terms of sound quality and overall versatility. The MC77 plug-in is definitely usable and is nice to have in my arsenal, but isn't my top choice by a long shot.
