Tony has the right answer. A DAW and BiaB are two different tools.
Add a notation app to that and it’s three tools. It all depends on the project.
For me, it may start in Sibelius (by a client) and end up in Notion. Mine might start in Encore and/or Finale and get synced to Digital Performer via Rewire—even though the code is depreciated, RW still works on the MacOS. Others begin and end in DP — or GarageBand/Logic/Audacity/Reaper/Bitwig/Zoom and end in DP.
Very few of my own projects never begin in BIAB but many of my clients’ do. Normally, if I begin in BIAB, I finish in it but not always.
Back t the hammer and screw metaphor: Nearly all AV presentations have video elements mixed with slides or are straight video. I do these in Premiere Elements or FinalCut ProX depending on complexity — easy peasy. However, yesterday, I started a 2-hour project that is slides and music only. I fired up PE and was 10 minutes into it when I realized that, though I can do it as a video, PowerPoint was the far superior app—I’d not used PP in 20 years but it was easy to get back in the saddle.
Again, it all depends on the project. I do this for a living.
