I've just uploaded a simple ASIO VST host for Windows, called Niall's Pedal Board.

It's not particularly complex - it allows you to load plugins and control their parameters using joystick controls.
I made it so I could use my laptop as a kind of pedal board for my guitar, using the circuitry from a cheap joystick to connect a bunch of switches and expression pedals to the laptop. Here's a picture of what I built:

I included a brief walkthrough of how I made it in the zip if anyone wants to have a go themselves.
The program's GPL'ed and written using the fantastic JUCE library. You can download it from here.
- Niall.
