Wow, where should I start. Well, I just picked up this peice about a week ago and let me tell you, it is first off, overwhelming with features. Second, the learning curve is rather high but with the optional Vido or DVD, no problem to get started recording. If you have quite a bit of experience with routing and recording, then you should really have no problem getting started. Then, all you have to do is mess around for a while and read the manual and you will learn the "deep" features of this MONSTER.
Honestly, for the price I paid ($1500 USD) nothing can compare. I use to record onto a PowerMac through an Even EZbus which together cost me around $1800 and that seriously can't even come close to touching the rock solid, AWSOME sounding, appeal of the Aw.
But, there are some pretty bad flaws. For one, the editing can use some MAJOR re-work. Luckily I will not be doing major editing considering I am all MIDI based recording. But, when I start recording local bands and Vocalists, then It is going to be harder to edit stuff. But, it still works, just takes alittle more time. I am positive in Yamaha that this will be updated on their next OS update.
Other than that minor flaw so far, everything else that I have used is amazing. For the price that they are going for used, there is no reason why any home studio or even project studio shouldn't be using one. For goodness sakes, it is a MINI O3D in there! Yamaha, I am very impressed. To top it all off, Yamaha online saport is great. All I had to do was register the the Aw online (which took a matter of minutes) and they are sending me an OS update on CD AND 30 free CD-R's to get me going! Thanks Yam. And no, I don't work for Yamaha! hehe. But, if you walked into my studio you would think that I am sponsored by them or something. I now own the Aw4416, the Rs7000 (which I love more than my girl friend), and the Yamaha An1x.
Iam giving it an 8 becuase it loses 2 points for the minor OS quirks that can VERY EASily be fixed by Yamaha in the very near future.
