I run Digital Performer with only a couple of tracks and midi for keyboard and flute, using a Saffire LE. We have on old mac dual processor and want to replace it before it dies. I want a Mac Pro, my husband thinks a Mini would be fine. My concern about the Mini is the HD speed of 5400 vs the 7200 on the Pro. I've never used a slower HD than 7200. Is anyone using a mini for audio? How does it perform?
