I tried plugin on a few occasions...
However, I will still use BIAB 99% of the time.
If a plugin is a "way" to rewrite BIAB, perhaps it is a good start. However with so many things that are missing that are in BIAB, I hardly find a use for it.
Ideally, I would want a single platform. For example like Halion Sonic (or Kontakt) You can use it as a standalone or as VST with almost identical interface and functions. With PG plugin it is another game that I have to learn. I am keeping an eye on it, but for now I still feel it is in very early stage. Maybe it is a good idea to slow down new features flow and focus on strengthening software, giving more time to consider suggestions and for beta users to test it thoroughly?
One more paragraph

I was very frustrated when I tried BIAB for the first time. One forum member suggested that I should approach it with "open mind". I am glad I did. Now, I want to give same advise to PG & staff. Talk to somebody who is ace in music software programming with "open mind". See what they have to say... especially what they would prioritize/focus on if it was their fish to fry. (I am talking about design+functions, not RT/RD/Midi content here)
