You don’t need to know everything in a DAW though, only what your trying to do.
I’m not a film/Tv composer, so the Expression maps, Dorico elements, Using Timecode, is irrelevant to me.
Just like my car, I use it to get to A/B, I have never wasted time reading the manual on how the digital radio works, or the multiple variations of the air-con system, or how to change the front lights up to down in angle, waste of my time.
When you know what your trying to do, you only need to know 30% of the DAW.
Once you know your 30% and you have your Key commands for your tasks, your set. Each DAW is the same, you learn that little bit you need and off you go.
Its when you waste time doing things inside them that are pointless to your outcome, that cause people to struggle.
Cubase = learn 100% (wont need most of it)
Or
learn = Cubase33%, Ableton 33%, Bitwig 33%.
If your scoring for films/tv, you don’t waste time with endless sound design techniques & bouncing/rendering of file options.
You focus on your Expression maps, giant sample library’s and made to measure template set-ups of already proven sample libraries.
You don’t spend 5 hours inventing new sounds, when you have a 100GB library that Hans Zimmer uses.
I take the Steve Jobs | Apple, approach, learn what to say no to and learn what to say yes to. Everything is signal or noise. Important non important. If I can get what i need across 3 and only need to know 30% from each, then that’s better than knowing 100% of 1 but never needing 70% of it.
