Ouch..your room is almost square, get good small speakers lol. PC part is still a little unforunate when looking at perfomance osx vs windows, coreaudio whoops major ass when it comes to latency. In fact, a macbook running pt9 rightnow would have no latency problems at all when using the ONBOARD soundcard' i/o. On a pc, regardless of what windows version you're going to run, you always have 2ms latency. Not that it underlines what's key about osx, but osx is spot on for running a daw. Dont get me wrong either on windows, been using windows daws for years and as long as its itb and pre-production you'll find nothing wrong. On recording you'll get the most hardware support from osx, best support for daw. You could go hackintosh but be warned that some pci-e cards dont work properly (rme/ssl).
The artist mix is nice, by the looks, features, everything you're going to need is there, motorized and touchsensitive. Its not made for any specific daw but it adapts the easiest to logic and pt(there's templates for everything, but for those 2 its pretty much connect/go).
It DOES have some issues; the previous and first model had cheap(recycled)covers which tend to break easy and thats not even remotely funny considering the price. The avid is probably exactly the same, different color, different logo. The Avid artist mix has had a lousy firmware upgrade as a follow up to the euphonix since they havent found out the proper encoding for motorized faders. The faders receive a digital signal stating to which position it should go but they got the trimming all wrong. It looks and sounds like a servo which you want give a pulse to move beyond its reach. Its stutters, shakey moves and noise emitting telling you it does not compute. Im guessing Avid went ahead to hastly workout the firmware upgrade and never got this right, but shit gotta sell lol (imo, this isnt a hardware bug, just sloppy firmware).
TBH, we've been looking to acquire them in the studio since they got out but we're just not convinced yet. I could see Euphonix developing an army grade controller if you like, but Avid/M-audio sometimes makes me want to cry, ergo, i dont think they will improve much of it (i think theyve said that the bugfixes to the current firmware should be available in september...)
The major annoying ffin thing is, its still the best design out there. When i look at it i think "i dont need more, i dont need less..this is it".
