Native Instruments has released Driver, a distortion and filter effect for Windows and Mac. Until December 31st, this plug-in is available for free. After that it costs 49 euros.
Driver seems to sound good, which is currently one of the reasons of the heavy traffic load on Native Instrument’s server. So you need some patience if you want to download the plug-in today. The download link and activation code is sent after filling in a valid e-mail address on the website of Native Instruments.
