Based on feedback I got to a post on this site last Summer I ended up buying an mBox. I have to say I'm very disappointed. First, some background: I sold my analog recording studio when my family (2 young kids and wife) and I moved from a house to an apartment. Space is an issue, but so is time with two small kids. I used to perform professionally, mostly as a musical-theatre actor/singer and occasionally as a pianist. I also write songs and play guitar. I have an extensive set of home demos recorded on a Fostex 8-track reel-to-reel. I have a nice grand piano in my apartment as well as a low-end Martin Guitar. I teach technology at a local high school and recently moved from using Windows and Linux on a Dell computer to a Mac PowerBook G4 (kind of like moving from a Hyundai to a Mercedes). When I sold my analog gear, I kept a few good mics, including a condensor vocal mic and a home-made stereo mic rig built with Radio Shack (aka Crown) PZMs and plexiglass. What I wanted was a simple, high quality way of recording demo recordings of my piano and voice or my guitar and voice. The mBox touts its high-quality preamps. I was a little concerned that it used USB1 rather than FireWire, but figured that for 2-channel recording there would be enough throughput. The results were disappointing. The sound quality is fine. The problem has been getting the system to work with my computers. My Dell Inspiron 8200 has a Pentium IV processor with 768MB of RAM and runs at 1.4 GHz. It's running Windows XP SP2. After a few minutes, ProTools would stop recording and complain about the cache size or something similar. After tweaking the settings (which increased the playback latency), I finally got it to work consistently, but I still feel like I couldn't count on it. I would be worried, for instance, if I was doing a live recording of something I really cared about. I bought a Mac PowerBook G4 in August. It's a much better machine than the Dell. It has the exact same amount of memory and same processing speed, but it seems to run faster and has no problem with tasks like editing video, which the Dell had problems with. I tried the Mac with ProTools and the mBox, and I got the same messages about the cache size. What gives? I can record, playback, and edit NTSC video in real time, but ProTools can't even record 2 channels of audio without crapping out. (This is even when I used NO effects whatsoever and recorded onto a clean session.) Again, after adjusting the parameters to the maximum settings (increasing the latency and so on), it seemed to work O.K. Then, however, I upgraded my OS per the normal Mac Upgrade Software process, and ProTools doesn't work anymore on my computer. So, here my beef with Digidesign begins. I hunted around their website, and they offer a new version of their software, but only to people who bought their mBox since October 2004 (I bought mine, I think, in July). I called customer service and explained to them that I don't care about bells and whistles; I just want the mBox to work on my Mac. They hemmed and hawed about upgrading, so I responded by sending in all the registration info, receipts and so on. Currently, I'm waiting to see whether they will even respond to my request. I sent the stuff in about a month ago. ProTools seems to be much more than I need, but, worse than that, it doesn't seem to be 100% stable. I would like compression, reverb, and delay, but I don't need a whole lot of other stuff. I certainly don't need all the "Factory" plugins that I paid an extra $100 for. Indeed, I didn't bother to install that stuff on my Mac, because I find it annoying to have to use the USB key. What I do want, and I figure I'm entitled to for $550, is a stable recording playform that works with my state-of-the-art Mac computer and high-quality mics to give me professional quality demo recordings. Is this too much to ask? Anyway, if DigiDesign has a change of heart and actually helps me out, I'll let you all know. I do have one request for those of you who have perservered through my ranting. Could you recommend an alternative? My mBox is now basically a paperweight. I'm a computer guy -- after all I teach technology, but I'm sick of configuring and messing with settings. I would just like to run a program, press record, and go. I would use GarageBand, except that the mBox won't work with it. My priority is high quality, user-friendly recording. I liked that fact that the mBox was bus powered, so I could just set my laptop on a side table next to my piano with the mBox, plug in the mics, and go. Any suggestions? Thanks, Steve C.
