Hi Daz

1. The recommended spec to run Ivory is shown on the website. (The more powerful the better) http://www.synthogy.com/products/ivorygrand.html#features

2. It is a software program that comes on multiple DVDs and also requires an iLok Key. http://www.ilok.com/

3. You computer will need a Midi interface so that you can connect the Midi out of the Piano to the computer. (If your Piano comes with a USB Midi interface then you can use this)

4. You will need a high end (24bit) sound card with ASIO drivers, (Quality sound cards come with them as standard) and a cable to connect the Audio out of the soundcard to the input of your Piano.

Hope this helps

Bill
