The Massey Plug-ins CT4 Compressor doesn't take up much processing power at all and because of this I am pretty much able to have as many of these going at once as I'd like. I probably could have one on every track if I desired, although this depends a lot on what type of system you are using. I am currently running the Massey Plug-ins CT4 Compressor 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 in Pro Tools LE 7.4 and use a Digi 002R audio interface. I have also used this plug-in on a few different Pro Tools HD systems with great results. I've been using the Massey Plug-ins CT4 Compressor for between two and three years and I find myself liking it more and more every time that I use it.
The sound quality of the Massey Plug-ins CT4 Compressor is pretty outstanding as well as versatile. I use it on everything from vocals to electric and acoustic guitars. I also use it on bass guitar sometimes and often on drums. One of the best parts about this plug-in is that it is incredibly easy to use and it is quite easy to get a good sound from it. Simply turn up the compression a bit and make up it with the gain. I generally keep both the attack and release on fast, but it really depends on what I am compressing. While all of these things are great, the best part about the Massey Plug-ins CT4 Compressor is that it has a great free demo and to buy it is still only $69 USD! If you have a digital audio workspace or studio of any sort, do yourself a favor and at least download the free just about fully functional demo available on Massey's website!
