xoxos has released noise6, a freeware percussion/noise VST instrument for Windows PC.

noise6 features

• waveforms: saw, sine, square, sine*sine.
• frequency of each wavecycle varies between min and max settings, determined by random seed value.
• max slider ranges from 0 (same as minimum) to highest frequency.
• ‘mix’ amplitude modulates osc1 by osc2.
• gain: unity is middle, max is *4.
• squish: soft to hard clipping.
• punch: adds envelopes to audio signals before limiting

You can download noise6 here. A light version (without the limiter) is available here.
