SoundToys , makers of some very well-regarded plugins, seem to be starting a new tradition where they release new plugins each year at SXSW which include a fully-functional free version.
 
Here is a link to this year's freebie.
 PrimalTap

It's iLok related software.
 
No, thank you. 

From the video, it looks pretty interesting, especially the knob that doubles the delay and halves the sampling rate (if I remember correctly).

I installed the 64bit version of Primal Tap and configured the iLok license. It crashed Sonar X3 Pro 64bit every time I added the plug to a track. I immediately uninstalled it. It is a shame because it looks like a nice delay plug. It may just be a quirk with my system, but I have a number of great delay plugins and don't need anything that will make my system unstable.

you can choose to auth on the computer instead an ilok ....

you can choose to auth on the computer instead an ilok ....

 
But it says in order to enter the competition you need an ilok account so for those that don't, like me and many others, it's not ree at all because an Ilok account costs.
