I could create in bitwig and mix in mixbus.
I think you have a good point there with using different tools for the creating and mixing parts of the workflow!
There are many tools available that can be more inspiring to begin the music creation process with, than using the typical DAW.
But in the end you will probably need some serious DAW tools to do the mixing in.
I am leaning towards using Waveform for the MIDI creative tools, that include some interesting pattern generators. Well that, and/or Overture! Then use Studio one for the arranging and mixing.
But the creative alternatives depend on what you prefer to work with. I also have Ableton Live, which could be interesting to begin with, as well as would Bitwig, I imagine.
For those creating in the box, beginning in a less linear fashion would seem to offer more creative freedom than just a traditional linear track timeline and a mixer.
