I like Cool Edit Pro 2. I know, it is way out of date and no support on line. Since I bought a win.7 64 puter I can't get Cool Edit Pro 2 to work. There seems to be a driver problem that I havn't been able to fix. I have been using a trial version of Reaper. It is time to pay. I also want a small inter face for a midi keybosrd. The $160.00 difference in price makes since. I also have local support with Presonus at the dealer. I do pretty simple projects using BIAB and Real Band my bass playing and vocals. Also I do not have to carry a mixer to rrecord a steel or guitar track at a friends home. My portable rig cosists of a HP I-7 lap top, The Presonus Audio Box, 2 MD519 mics. a usb cord, 2 mic. cords, a FOSTEX PH-5 head phone amp., 2 FOSTEX T40 head phones. I can carry all of this in the trunk of my mmotor cycle. I like the near 0 latency feature with the interface. Thanks for asking. E.L.C.
