p0k has released Nibi v0.1, a stereo random/wired pitch shifter with feedback delay for Windows. It works well for pads and drums (especially to make "drill 'n' drum" sound).
p0k also recently released Uguisu v0.1, a waveshaper effect plug-in for Windows and Mac OS X, and updated the Windows version of Nezumi to v0.3.
All of these plug-ins are free and require Cycling '74's Pluggo Runtime.
