Ok. I just expected musicianship to be musicianship regardless of the instrument.
The hard parts for me are finding good arrangements, making stuff sound good in a mix, writing lyrics, finding ways to do certain non trivial things in my DAW, reviewing what software I want to purchase, ... Stuff like that.
It doesn't involve much focused dedicated practice. It's just too general of an activity, and it's very easy compared to playing classical pieces on a piano.
But how fun/relaxing it is can differ between instruments and between genres (baroque vs folk or blues) and approaches (e.g. strict sheet music interpration vs improvisation).
Also working with the DAW is more like composing, arranging, conducting, and producing/mixing than playing an instrument.
