I wish I could just yank out raw clips and load them into another DAW. Trouble is that many of these tracks utilize some pretty heavy FX chains which delve into the area of sound design, not just mix processing - and for that, I'm automating a lot of plugin parameters, sometimes 10-12 automation envelopes on each track. Then I have a few instances of StutterEdit in some of these FX chains, each with heavily modified patch banks being controlled MIDI tracks. by To recreate all of this another DAW would be a nightmare. Recreating the FX chains themselves (along with dozens of synths) would be a lot of work and involve the saving of hundreds of presets.
I've looked at Cubase a lot over the years and while it definitely seems a lot more stable and less troublesome than Sonar, it still suffers from way too much bloat and legacy for my tastes. That's why I settled on Bitwig, it being a lot more lean and heavily focused on the kind of stuff I do. My only worry was that it didn't support time signature changes (I use these a lot in certain projects), but now they've added that. There's a lot of "sound design" geared routing and processing that is definitely doable in DAW's like Sonar and Cubase, but with a lot more work and complexity. With Bitwig you can do things on one track that would have taken multiple tracks and auxes in Sonar, and I love that. Plus you can freely mix audio and MIDI on the same track, which again just gels with my way of thinking ("Why can't you do that if you want to?")
As DAW's get older, I think they become a lot more "boxed in" in terms of development - you're limited as to what you can implement and how you implement, because you're still having to accommodate legacy stuff going back years (decades in Sonar's case). Not just code, but overall design too. And you have a older user base which is more resistant to change, as well as having a lot more backwards compatibility to maintain. The big problem with older DAW's in my eyes is that they're very much based on the studio paradigm, i.e. trying to recreate a console and multitrack recorder with all the trimmings. This kind of design is optimized for a certain way of working - getting your composition and arrangement completed outside of the DAW (with your instruments), and then going in and recording it. The other way of working, which I prefer, is to experiment heavily with composition and arrangement (as well as sound design) in the box, so there's a lot of moving stuff around and trial and error and taking the composition this way and that. I'm beginning to see how much better DAW's like Bitwig and Ableton are for that workflow. However if large orchestral arrangements were my thing, I would definitely use Cubase.
