> Why would you have several VMs running on a music production machine?
This is not the question, you are altering the topic.
Just realize that Sonar can be used casually, I am pretty sure that majority of Sonar users are not professional musicians / audio engineers so why should they have a dedicated machine?
I already have a decent station I work on - hence VMs, btw.
Not sure if I need another, pretty powerful computer at home with another pair of monitors, separate audio, and another pair of speakers, leave alone the space required.
I understand that a dedicated machine is the right choice for pros but what about the vast majority of the others? ) Providing I am not asking for anything unusual.
