Great info here ! My dream is to build a homemade music studio .
I wanted to buy a mac and use Logic (no $ ) .
I think i can begin with ableton and maybe a midi keyboard as a start .
Cubase is for windows also . I had a friend producing psychedelic trance on cubase+midi only with great results.
A lot of plugins exists . I think you can take only what you need or like since there is a lot of them out there .
