I am compltely new to this. An old friend showed me his mixing desk wired up with Vienna and he explained it. I have been running a iMac 32gb with an RME and creating albums, but I have a lot of spare PC computers around, and this looked amazing. However most of my computers run old operating systems (deliberately). OS X Mavericks Cubase 7.5. and Windows 7 and XP, Could I run a system like this on those computers. I have some great 32bit samples from years back???? I really do not understand this at mo but looks very exciting.
