ODO recently released LiveTweaker, DrSid and MYFX AFM. All are available for Windows in the VST format and are free / donationware.
LiveTweaker is a multi-functional VST Instrument for Windows bringing together a 12-slot drum sampler, a drum synth and a monophonic synth in a single plug-in.
Conceived with live use in mind, the idea is to have 3 instruments on one single track for quick & easy tweaking using a MIDI controller. The second idea is to avoid sterile repetition of the same thing by including various random features. You can achieve subtle variations on a snare's pitch, a cymbal's decay, or simulate the osc pitch instability of an old analogue synth, but you can also turn your pattern into something totally different after each repetition. Livetweaker aims to keep things both simple, quick, and easy to use, all along with deep user customizable features for more sonic control.
DrSid is a simple sample based lo-fi/c64 synth VSTi for Windows with its sounds coming from an included collection of 320 samples. It has 6 sound/sample slots offering decay, tune and octave controls.
MYFX AFM is an FM (Frequency Modulation) and AM (Amplitude Modulation) VST effect plugin with 2 filters (switchable LP/HP/BP) and a "crosser".
