Here's what I'd like to see improved, as I have mentioned before in other threads:
1) A basic 16-pad sampler that can layer. Chandler's idea is spot on. I know a lot of you say buy a third-party solution, but my reasoning here (and for some of my other suggestions) is that most DAW's have this, and I think if you are going to call Cakewalk a 'competitor' then it should be competitive. I'd also like to get a companion feature to automatically split audio and have it create an instrument track with samples already mapped across the pads. I think Cakewalk recognized the lack of having this in Beatscape, but just really didn't end up executing it very well, and it was dropped.
2) Better audio warping/alignment. Mr. Anderton says AudioSnap is good, and it may be, but for me, trying to use it on a full mix it basically produces unusable results. I actually use Ableton to beat align/warp audio because it's so good, and maybe that's where it's going to stay, but from what I've seen, I don't think that Audiosnap (IMHO) is even as good as other DAW's, besides Ableton. I guess if I say that I need to prove it, and at some point, I'm going to do a head-to-head comparison of various DAW's audio warping facilities just so I can see if what I think is actually true.
3) Live recording of track output. Yes, many have asked for this. This would really be useful for on-the-fly sound design. Yeah, you can bounce, but it's not as useful, at least to me.
4) I would add an option to the Split Clips dialog to split at divisions of beats less than a measure, or maybe by the Snap Settings. I know you can do this manually, or you can go into Audiosnap, but the manual way is a bit cumbersome, and I don't think you should have to haul up Audiosnap to split beats.
Also, as an aside, I'd like to see Cakewalk get Ilan Bluestone (An EDM Producer that uses SONAR) in and have him do an artist's track walkthrough/seminar or something. I'd be VERY interested in how he's using Cakewalk to produce EDM with. I'd think Ilan would enjoy it, since he's done instruction on this kind of thing, and it would really be good for the SONAR brand as well.
No, I don't want more loops. Actually, don't really want more signature FX/ProChannel stuff either. I'd be content with the top two items. I do have work-arounds, but they are expensive or kill your workflow.
