Now they are trying to make money by having you pay a constant subscription fee ... Well ...
I'm always curious when new things get available, and I want to try them and give them a chance. But Mixbus (which I did try) ... in my eyes it is way below beta quality. Extremely unstable, ugly, uncomfortable, rudimentary ... I don't care if it sounds good as long as it isn't usable. I've deleted it for now and will wait until it works - or disappears from the market.
It's all about workflow. The problem is the tight bundling with Ardour, the worst "DAW" that has ever existed. If it was easy to plug Mixbus (just the mixer) into any DAW, that concept might work. But having to use Ardour is a no-go.
Just my opinion, of course.
