VerzerSampSynth VST instrument plugin It uses both sampling (using soundfonts) and synthesis to produce the harsh sounds. You can easily import your own SoundFonts to munge them up. The synth side of the instrument takes many of its parameters from the sampler sounds providing dynamic results. The interface is simple and easy to use. VerzerSampSynth comes with a handful of 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.
