I like to think I'm naturally pretty good with software, and although I've only been messing around with them for a couple of weeks, I'm beginning to feel at home fairly quickly in both Studio One 3 and Cubase Pro 9.5. They have lots of great features, some nice design ideas, etc. There are some neat tricks up their collective sleeves, and some clever innovations, etc yada yada yada...and its true. They are deep and capable, and I'll have no difficulty switching to either of them full time, when that day comes...
But even the fairly easy and intuitive things in SO3 and Cubase often have that one extra step, or that one additional and largely unnecessary detail that Sonar didn't have when it came to doing stuff. Bouncing midi tracks, is one example. All the DAWs can bounce midi tracks -- it's a pretty fundamental ability -- but none of them do it with the simple "select, click and done" efficiency of Sonar. I find that is a common theme when I'm comparing other DAWS to SPLAT. Sonar had a certain straightforward elegance in its implementation. "Why click three things, when you can get the same result by clicking two things?" seemed to be one of the governing principles of Sonar's bakers, it seems.
Cubase and SO3 always seem to have that one extra requirement, or that one additional toggle to select. And then there's Samplitude, where the guiding principle for bouncing and rendering seems to be "why use two steps, when we can use 27 steps in submenus they'd never expect, using menu items that aren't entirely clear in what they do, and then try not to laugh when they export 12 midi tracks to one file in a folder they can't find?"
But I digress...
Sonar wasn't perfect at everything, and there are things about both Cubase and SO3 that I like better (SO3's obsession with drag-and-drop everything is actually pretty nice), and I think Cubase's PRV editing tools are brilliant and about as close to perfect as I can imagine. But I will miss Sonar when it is no longer a viable product to use.
Just my half cents worth of thoughts on the topic.
