John, I was always under the impression that while I love Audition (1.5) and have utilized & purchased version 2.0 & 3.0 for some of my clients, CD burning has always been track at once and not disc at once. This might make it just fine for many but not for making stampers for replication purposes. That requires disc at once. But hey, if the client wants 1 or 2 CDs to send to the folks or grandparents, track at once might be adequate but it's nothing I've used for any professional application Or purpose, since 1996. This might be the reason why it was eliminated in this new 5.5 version? I haven't bothered to upgrade mine because it doesn't really sound like much of a really good reason to do so? Of course 1.5 is not ASIO enabled like their later versions. I actually prefer my 1.5 over 3 except when I need that ASIO support such as for my Digi M-box 2 if I'm not using semi-Pro Tools. For multitrack purposes, I generally get around that by utilizing my HD 24XR. I rarely need more than 2 tracks to record with on my laptops/desktops. Occasionally 4 but that's what the other M-box2 can do with an external A/D converter which is a kludge. This might really be one of those updates that is more from a marketing standpoint than an actual update/upgrade. Like the automobile manufacturers, one must change the style of the turn signal lens for next year's model. We might all be audio professionals but we still have to have a little reason to jump.
