Coldfire Software recently released DistBit, a flexible distortion/shaping effect intended for use on a wide variety of material. It consists of a pair of multi-mode filters, a pair of distortion units, and a routing system to allow all various combinations of the four devices on the signal. It was inspired by the Scream4 unit in Propellerhead Software's Reason.
DistBit is free and is available as a VST effect plug-in for Windows.
