Verzerquadosc is a VST instrument plug-in (requires a VST compatable host program such as Fruity Loops, Logic, etc.) that sports 4 oscillators with the first three being used to manipulate parameters of the fourth. With global graphical waveshape editing, quantisation, and cut-off filtering you can really mold a unique sound. This is a very flexible synth with a special knack for making harsh and abrasive tones within a simple interface. Verzerquadosc comes with 12 pre-programmed sample patches to give you an idea of what it's capable of. If your VST host program allows it, you can store up to 128 of your own custom patches.
