DMOBag contains VST wrapper plugins for all so-called DMOs (DirectX Media Objects)
included with DirectX9. You only need to have DX9 installed, then you get two cool
reverbs (one from Waves!), chorus, flanger, gargle, EQ, distortion, compressor and
echo, all for free...

And they are even multi-channel capable, with up to 16 input and output channels!
For more details see the included manual.

I made a VST plugin for each DMO, added a GUI (see below) as well as VST
parameter automation and external MIDI CC control.

Oh yes, and the full Delphi source code is also included :-)

Don't complain about the quality of the DMO effects though, I have no influence
on them, they were coded by Microsoft, I just wrapped them. This is also valid for
the parameter ranges, descriptions and features - the VST wrapper presents you
just the options and ranges that Microsoft defined.

Here are some screenshots, the other included plugins look quite similar:
