full version of cubase 4 mac and pc compatible. this is not an educational, reseller only, volume or whatever licence. it is a plain retail customer licence. i'm selling this because i switched to logic. the product is activated but not registered with steinberg online so you can do it yourself. i only opened the box once to make the activation to ensure everything will be ok to sell it then. as it is a version upgraded from a previous version of cubase, i'll include invoices, previous original versions and a selling act for you to have the total and unique ownership of the item (as stated in steinberg licence text for transfering ownership of their products).
