For those who don't have a Digital Audio Workstation or any kind of plugin host on their computer, and are just curious and would like to play around with these, I highly recommend Hermann Seib's free little applet, vstHost available here:
www.hermannseib.com/english/vsthost.htm
You won't even need a MIDI keyboard connected to your computer.

The plugs are 32-bit, Windows-only; they cannot be made Mac-compatible because they were made with Synthmaker, which doesn't support it; nor it's current version, Flowstone (I know - talk to them!).  To use these on a 64-bit system, there's jBridge : jstuff.wordpress.com/jbridge/
