No, I would not define myself as a power user at this point. I am slowing getting back into the home studio / DAW world and am finding that things have evolved quite a bit. Lots of new features (generally speaking) especially with regard to production workflow for commercial work, mixing, tracking to video, and the increasing trend towards samples and clips. Much of that is outside my needs. So I'm finding with programs such as Cubase (for example), there's quite a lot to sort through and whittle down.

I have liked BIAB in the past not only a sketch pad, but as a very good generator of MIDI parts. I would then export to Cubase (home), or even send to the studio guys, and get it edited and apply different sample libraries, etc. That said, as a sketch pad BIAB would seem to be better than ever with all the built-in sampled instruments/styles. A better sounding rending without having to link up massive external sample libraries like I did in the past. With my very new DAW now (years later), I haven't even bought massive sample libraries yet...still exploring and deliberately making choices slowly.
