It’s not hard to make any DAW fall to pieces. All it takes is cranky plugins or unusual hardware configurations. A manufacturer could easily invest all of their resources into trying to accommodate all of the edge cases out there – and for something as broad and expandable as a mature, VST-compatible DAW, there are a lot of edge cases.
Hence I find it difficult to get exercised about the supposed stability boogeyman hiding in Cubase’s closet (and I’ve filed my own bug reports, check my post history). Oh, it turns out that the latest Cubase crashed with your five million plugins running on Windows ME deployed on the Amazon Cloud? I’m shocked, shocked I say.
