Yeah, definitely not as discrete.
But I think there's a danger to doing everything at once, I usually get distracted by synth design or DSP, then start trying to change the design or the DSP to fit the sound into the mix.
I'm fairly certain my mixes would be a lot tighter if I exported parts and mixed them together, instead of trying to do everything at once.
Seem to have developed a phobia of exporting parts and mixing them. Something about it seems too final....
