I dunno if 'threaded' is the correct word, but it's definitely FANTASTIC at letting you play back and work without interruption.
IOW: in every other type of audio, video, photo, text editor I've used, you have to stop playback during a surprising number of tasks. Cubase almost -never- requires one to stop auditioning.
You don't realise that until you work on other programs where stopping every time you want to add or edit something or modify a setting stops everything. I've come to take it so for granted and I -never- think to give SB credit but it's truly amazing.
I grouse a LOT about the UI but truthfully? If I had to choose between this capability and a more modern 'dockable' UI I'd choose this any day of the week.
IOW: if the price of a new UI would be losing this seamless playback under almost all circumstances I'd be strongly tempted to just stick with the current version.
For example, the ONE thing that drives me nuts about Adobe products, which I've written have a very nice UI, is that you have to -stop- all the time when you alter just about -anything-. But when I've groused about it on Adobe Forums the people are sincerely puzzled. They can't imagine being able to say, change an automation point without stopping playback. Something as simple as turning an effect on/off? Gotta stop playback. Because they've =never= had that ability it just doesn't seem to phase 'em. I tolerate it in CS because I only spend a few hours a week with it. But I'm having trouble imagining a DAW world with all those stops/starts.
Maybe competitors are better now, but I noticed that other DAWs I've tried over the years were not quite as 'always on' and if I had stuck with them it definitely would've started to grind. Maybe I've been living under a rock and this is now SOP, but I still find this pretty fantastic.
I dunno how it translates as a feature on a box... but it's worth noting from time to time. The core of Cubase is quite something.
