The infamous FSU plugin is back! And yes, there's finally a Mac version! Glitch is an audio effect plugin for Windows (VST), Mac (VST and AU) and Linux (VST), available in both 32-bit and 64-bit formats. Featuring a new and improved sequencer which can play multiple effects simultaneously, with the ability to trigger unique scenes from every note on your keyboard, Glitch can be as gentle or as brutal as you like.
