To some extent, Bitwig being created by a synth designer, shows the proclivity to have a lot of flexible internal connectivity
for producing the desired result, without needing much from the outside world. As a business model, Bitwig daw provides
sounds, instruments, effects, and some mastering, so a purchaser/subscriber can get started once the interface and labels are assimilated.
I'm not fond of the interface or the labeling, but the effects are drag-n-drop, so it's easy to concoct 'interesting' new chains. 
I suspect Bitwig is no more or less convoluted than linux audio, so it's a fine hoot that they keep the linux version alive 
I do think it would take quite a few hours, some video tutorials, and some good note-taking, for someone used to another daw,
to achieve a peaceful state of being with the record button. As should be the case, when providing a comprehnsive package.
Better to have Bitwig, Mixbus, Ardour, Qtractor, and Reaper, than be subserviant to Ableton, Cubase, Logic, and Pro-Tools. 
I use Reaper myself, for simple music, often with audacity and standalone apps running, in addition to whatever internal plugins
or external hardware are found in the way. Simple and symmetrical, and doesn't challenge my IQ.
sudo modprobe snd_virmidi is about as deep as I want to go...when Bitwig 16-Track is on sale for $40, I'll cash in my Pepsi cans,
and have a go
