When CW offered lifetime subscriptions, I started looking at other DAW's. Today, I can tell you that the latest up date of Studio One 3.5 is no slouch. Midi implementation, especially for composition in arrangement mode and scratch pads are ridiculous. Plugs are drag and drop (everything is drag and drop). Plugs are solid, the included sampler is very good, and for the low price of half off (and rumours of a discount for CW refugees) at the moment.
I will say that my work is very much either audio or MIDI composition/production. Studio One 3 is better at most things that count for me (stability, latency, support etc - the PreSonus community is good).
I've been through it before (not with a DAW) and I'm sure I'll have to go through it again. Cakewalk is fine, but it's on the stagnation path. The product's stability isn't matched by the company's stability, and for me (especially since I'm starting a two year project), that really matters. So I'm formally finishing up my last projects in SPlat. Everything new will be done in S1.
All that said, is S1 all that and a bag of chips? Yeah, it's pretty solid. The interface is infinitely more navigable. There are multiple ways to navigate, I love the zero latency mode, latency monitoring, project mode. Like, it's a really serious tool. I have to say, for me personally, the interface delivers on a really smooth workflow. I used to record simple tracks in Sound Forge because I found Sonar really cranky about attaching to my outboard gear. The few times I did, I still exported to Sound Forge to speed up editing interviews. In S1 I do everything in S1. There's no need to round trip...I just go into edit mode and use the editor (which as some pretty slick features).
As for MIDI, I'm not sure what MIDI features you're missing, but it might be advisable to do a deep dive before you discount S1. I'm finding the quantize, and other performance tools really interesting (the equivalent of Sonar's midi process tools are the same, but a little different).
That's the best way to explain the difference between any two DAWs: the same, but different. Professionals use both. Amateurs use both. You can do 99.8% of exactly the same things between them. The difference is how the software lets you do your job, and how it handles its job. To me S1 is superior, but that's just me.
I've been with Cakewalk since whatever the DOS version bundled with a Soundblaster was. Seriously, like, 26ish years? I'm comfortable with it. It's fun. It's easy. It's mostly reliable (though progressively less in the last couple updates). I'm a little nostaglic, but mostly I worry about the staff.
As for the company, I found it interesting the CTO (head code monkey) made the announcement. I wonder if it wasn't a matter of "we can re-fresh the code, but we need to invest in it." Gibson is like the borg: acquire, consume, expel.
In any case, we're all in the same boat. It's not like Sonar is suddenly dead. It's just not going to develop. As I've said, my past and archive access will be Sonar. Sadly, but not very, the future will be with S1.
Cheers to everyone for the help over the years (I still may need some as I retrieve old projects). And all the best to the Bakers and Staff and Cakewalk. You're definitely in our thoughts this Thanksgiving.
