Well, I have a Firebox and had a small problem getting it to run as my default audio device in Vista 64. I have a dual boot PC with Vista 64 on one drive and XP 32 bit on the other. I record to Cubase SX3 on the XP drive, but figured I'd use the Firebox for sound on both channels, so I can use my monitors to listen to music, etc. Anyway, I got talking to the tech guy and mentioned the Firestudio mobile and he is saying it is as good as any device out there- even RME- so I get interested and buy it at GC making sure I can return it if I don't fall in love with the thing. So I install the drivers for Firestudio Mobile in XP and get some sound coming out of it. Then I run Cubase SX3 and the clock won't sync. Then I try to uninstall the existing Presonus Firebox drivers, but I can't uninstall them. I get an error. I unplug both devices (they were not hooked up at the same time) and restart. I try uninstalling the drivers for both the Firebox and Firestudio, but fail at both. I download a program that tries to force uninstall them and it says it succeeded, but both drivers are still there. I restart the computer 20 times but cannot uninstall anything at all. The Firebox still works perfectly, so I guess I'm sticking with that. I will call Presonus on Monday when it opens. They will probably tell me to reinstall Windows from scratch and then install the Firestudio. Not gonna happen- too much of a hastle. I guess writing drivers is a big complicated deal and relatively small companies like this have trouble doing a good job. I mean small relative to ATI, NVidia, Asus and companies like that with millions of customers. I did get Firestudio working briefly as stated earlier in the desktop environment even though I could not get it set up to record with in Cubase SX3. The only comments I have are that the headphone amp is about 4x weaker in volume than the Firebox and the same can be said of the main level controller. I'm not saying this thing is hopeless, but if you are like me and think you are going to painlessly upgrade from a Firebox to a Firestudio Mobile and just pick up your home recording hobby where you left off, it probably isn't going to be that simple. Good luck if you try it. If you are willing to reformat your entire hard drive and start fresh, it will probably work. As for the Firestudio mobile being as good as an RME Fireface, I doubt that claim, but I just had to see after the tech guy said so. I can't resist stunning quality on the cheap, but usually it's too good to be true. I was hoping that since microprocessor technology is always getting smaller, faster, cheaper, better, that it might be true. Maybe it is. You try it out and post something if you want to try.
