I struggled for a couple of months with my new DAW system, and I thought that the USB Fast Track Ultra interface I was using was causing me trouble. First, I am not 100% convinced that Windows 7 is stable enough for music use yet: I was seriously considering taking the new HP system I bought back in November (Core i7/860, 1TB HDD, 8GB RAM) back to the store, because I was experiencing a lot of crashes, and very slow, overloaded performance that made me wish for the PC-XT that I used back in 1986, because it ran better. This new machine is supposed to be a powerhouse, but it wasn't acting like one. At least on the XT, I didn't spend so much time watching the old "Blue Donut" and seeing the Blue Screen filled with hexadecimal mumbo-jumbo, or having Cubase 5 taking half a minute to change screens and just showing me white boxes in place of the Transport Bar, while the red ASIO Overload light in the upper LH corner of the Transport Bar was lit all the time. Those in this forum have heard of my troubles, but there is good news: I just about considered deleting Windows 7 from the machine and reloading a copy of XT instead, because I know that works. However, I think I've gotten W7 straightened out a bit now. I took the M-Audio box back to the store (I had an old M-Audio MIDI breakout box a few years ago, and I had trouble with it, too, so I quit using it and it just got dusty under my desk until I junked it) and exchanged it for a PreSonus Firestudio Mobile with a FireWire interface instead of USB. Upon installation, I had some glitches, but once I went to the PreSonus site, downloaded the newest driver, and installed it, I think it's starting to come together now. I don't think I need to get a Mac, dump W7, or do anything like that. I haven't explored the PreSonus far enough yet to see if I'm still getting sticking MIDI notes, or the echoing MIDI that I was experiencing before. One problem still perplexes me, though: I see the green "MIDI OUT" bar on the Transport Bar flashing in time, and I hear this very slight SH SH SH SH through my speakers, sort of like a "heartbeat", and I don't know that that could be from. I'm going to keep on doing music with this system and try to overcome the issues, but I don't always know enough to deal with some of the things that come up. Hopefully, the problems will be fewer and farther between. At my age, I don't have that much hair to pull out anymore!
