Matt:

Thanks. I'm now using Sonar 8.5, but on XP, sp3 Pentium 4, 2.8 GHz.

It's time to get an i5 or i7.

I just can't decide if I should stick with an m-audio pci card like I've been using or go with a USB audio/midi interface.

Off-the-shelf computers with i7 and a pci slot are getting hard to find.

Thanks again.

John
