Interesting idea for the reasons you mention, but I think Subscription models are only tolerable when the added value far surpasses what one could afford to buy outright.
For example, I’m on the “Adobe Cloud” (rolls eyes) monthly subscription and get about 6 hard-hitting applications that I didn’t get with the package I purchased before the cloud was available.
Even with all this added value, I still don’t like not owning the software.
So for something like Cubase it would really bother me. Every month I’d be cursing the bill. There would be no added value. And since I already own it, the monthly fee would have to be really, really low.
Man, even just thinking about a monthly fee for Cubase is unsettling.
Especially for a product category where at any moment, the version I’m on may be the version I’m stuck with for a long time, due to incompatibilities with all the moving parts of 3rd party plugins, hardware controllers, etc.
No, I think a DAW is something we’re going to have to own.
That is, unless Steinberg wants to invent a VST spec so bullet proof (and shift everyone on it) that it ensures everything will work all the time, for everyone. Ditto for all the hardware that’s out there.
So, that’s not gonna happen.
I’m so gun-shy about updates at this point, I just bought a second 128GB backup SSD just for 8.0.5 so that I don’t have to erase my 8.0.0 backup (that just saved my butt with an internet virus). I’m gonna keep two rotating image backups now.
Which bring me to my next point. I’m like “this close” to taking the good advice of others and unplugging my DAW from the internet, completely. And a DAW under a monthly subscription service, but without an internet connection would be a nightmare.
