Does anyone know of any websites that have audio demo clips from any of the Yamaha plug-in boards? There seems to be a lot of audio demos for their keyboards, but not the boards. They're synths too, I would love to hear before buying any of them.

Sean,
I don't remember the full link now, but the demo's you are asking about are on the Yamaha Europe site (you should perform a search there).

Here's the full link for the Europe site:

but a better site is:
