My excitement about "4k" and "scalable" UI caused some questions/confusion, so I wanted to elaborate (speculate) based on Jesse's response:
1. It sounds like those who want the existing scale/size of Cakewalk to stay the same will be able to have that. The update will not force your UI to be giant.
2. When I said "scalable" I meant that the UI will scale to match Windows's scaling setting. It already does! It's just blurry, right now, when scaled. With the vector based update, it will not be blurry. (Depending on how they code it, they could put the scaling % in the preferences so it can be independent of Windows scaling.)
3. If you don't want the scaling -- as with all applications you can set it in the shortcut's "Change high DPI settings" option. This is something they could add in the preferences as well.
4. Other applications have proven that vector based UI doesn't have to be a performance problem. If they encounter performance issues, they can use a process that bakes scaled images based on the resolution needed, at which case performance is identical to bitmap. One of the Cakewalk engineers alluded to this (or something like it) as a solution if necessary. Bottom line? They got it covered!
So there's no reason to panic about the vector update! It's only a good thing... And it will make Cakewalk viable for more users. Understand that right now any 4k laptop is stuck with microscopic UI or very blurry UI. The update will solve that!
And anyone whose vision isn't what it once was, even on a 32 inch 4k monitor Cakewalk is a little small. 125% or 150% is perfect (or will be, once the vector update is released.)
PS. Even if you don't need the vector update, it's represents something very positive from Bandlab: This is the type of update you do when you have long term plans for a product. It bodes well for the future! Let's help the team have a successful launch, and SONAR can grow as the userbase does!
