I would love to purchase a Mac to replace a PC on which I used to record my own original music - I was never able to solve the problem of my vocals lagging behind the arrangement. I read many forums at the time, and not one soul could ever seem to solve the problem for anyone experiencing this annoyance. I don't want to make the same mistake twice: I've done a little research and am finding people have the same trouble with Macs. I see that there are all sorts of suggestions to solve the problem, but no one ever writes back to say "Yes, thanks, that worked for me!" Can anyone tell me, if I buy a new Mac for composing on, am I going to likely struggle with this same problem? If I am I may as well just bite the bullet and rent a studio when I want to record.
