I got a really slow MacBook Pro from 2007 running Cubase 7.5 under 10.9.3. My first impressions were...." i need a new machine to enjoy these nice sounds....this is really sucking all my CPU" Then I found the ProTools expert youtube and at the end, the guy showed it giving a very low CPU hit. Hmmm, wonder if i'm doing something wrong? It showed high CPU use for me in Reaper as well.
