Pipeline, call me lazy or something else...
I am watching plugin closely, but it is still very stripped down compared to BIAB. Another thing, plugin is within DAW, so even if it gains all the features of BIAB, it would still be environment(Plugin) within environment(DAW). I would like to have BIAB (or future re-incarnation) as a standalone program too. As big boys at NI (Kontakt, etc.) or other soft devs have it: Standalone + Plugin. And in case of Komplete or Halion, I am using both: a standalone and plugin.

I do see myself using PG plugin in the future, when it matures further, but not yet. Same as with BIAB. I tried it a decade+ ago and it did not cut it for me. Now, it is a software of choice and I am sure it will stay with me for many years as I only begun scratching the surface of content.
