From the SoundToys website: “Little Radiator™ gives you the warm sound of the classic Altec 1566A tube mic preamp, and it’s totally free (for a limited time).”
Super cool.

So shortly after PT9, and PT 10 is here. 
I’ve only been using it a couple of days, and I’ve got my old PT9 system backed up just in case, but so far the new features are pretty cool.
Definitely not happy about the price, but I bought the upgrade on one of the “3 payment; get it now” deals, so I’m dealing with it.

A speaker and micing simulator. The free version features 1 model of power amp simulation (EL34 / AB class), 1 speaker cab (based on a Marshall 4×12) and 1 type of microphone (based on a Shure SM57).
Avid has announced the release of Pro Tools 9, the most surprising release of Pro Tools to date! 
Here are just a few of the new features:
Just a little taste. More info to come.
Free plugins are plugins that the manufacturer of the plugin provides free for use, or fully functioning limited versions that are free to use and can have the limitations removed by purchasing.
Unfortunately for everyone, many people often confuse “illegal” plugins, plugins that have had their copy protections removed illegally (“cracked”), as “free” plugins. Those are not “free” plugins, those are “illegal” plugins. While you may be able to obtain these plugins for “free”, they are not, indeed, free.
Another instance of this is “receiving plugins from friends”, where “friends” provide you with a copy of their plugins directory. (just a heads up; most times this doesn’t work due to other missing dependencies). This is also illegal; you did not pay to use those plugins.
There are many actual free and useful plugins available. I’ve listed many of them here on this site, but there are many others that you can find on the net. Most (if not all) of the actual free plugins have user agreements that prohibit distributing them second hand, so I can only provide links here. However, many of the free plugins you might “find” on the internet are actually cracked, illegal copies of plugins that normally require purchase. I strongly discourage the use of these plugins for many, many reasons.
Many users have come across cracked plugins and have been tempted to use, or actually used them. I would like to plead with users not to do this. No matter what your reason for doing it is, no matter what excuse you give (“They’re too expensive”, “the Copy protection screws up my machine”, etc) they are still just that, excuses, and it is still just plain wrong.
There are plenty of alternatives:

So, getting to the answer to the question; what are free plugins?
Bottom line, don’t use cracked plugins. Ever.

OK, this one is a “no-brainer”. The newest version of Sampletank Free (2.5) is a “full-featured” version of Sampletank. It comes with 500MB of samples for free (don’t forget to download them; they’re separate), but unlike previous versions, can also be expanded just by purchasing the sample sets available from the “Powered by SampleTank” range and any of the “Expansion Tank 2″ sound sets, as well as importing your own WAV, AIFF, SDII, AKAI S-1000/3000, and Samplecell files.
It has all of the features of the full fledged product, just not the sample sets (which can be purchased at a later time if you wish).
Again, for free? A no-brainer must-have. Seriously.

The U-NO-62 is a polyphonic analogue synth modeled after the famous Roland JUNO-60. For any fan of analogue synths, this is a must-have.
To use this plugin in Pro Tools, you need to purchase the VST-RTAS adapter from FXPansion (highly recommended, and worth every single penny).

From the Elysia website:
“Its main function is to change the proportions between high and low frequencies. The principle is quite similar to a pair of scales: Dependent on the gain setting around a variable center frequency, the high frequencies are boosted whereas the low frequencies are attenuated (or vice versa) at the same time.”

8 free plugins. Not just one; 8!
Blue Cat Audio has a bundle of free plugins available for download that include:
Whether or not they will be useful to you is really up to you, but at the price (FREE!) they are definitely worth a try.
