Useful Free Audio Units Plugins for Logic
KVR Audio provides an extensive database of audio plugins in most formats, both free and pay. In general that’s a good place to start if you have something specific you’re looking for. To get you started though, here’s a few useful free Audio Unit plugins (for the Mac, of course - though most have Windows versions as well). Some come with an installer; others consist of simply a .component file, which you place in the Library -> Audio -> Plug-ins -> Components folder to install.
Frohmage: multi-band resonant filter. Can be a little tricky to tweak with any precision, but provides a nice metallic crunchiness to what you put it on.
KTGranulator: granular synthesis plugin. Quite a unique sound - and hard to find plugins that do this well.
Cyanide 2: Waveshaper (digital distortion). Absolutely brutal digital distortion. Nothing warm and fuzzy with this one.
LAConvolver: Convolution reverb. Simple interface, but with the right impulse response files can sound terrific. Try http://www.kvraudio.com/forum/printview.php?t=62458&start=0 as a place to find some good impulse response files.
C3 Multi-band Compressor: Compressor. Nice for tweaking a mix in just the right way - toning down the bass a little, or adding a little of the right kind of punch.
