Charlie, thank you for suggestions. Yes, the 4 chord helps somewhat, but I do not want to feel like a juggler. That is why I am requesting for a solution not a partial workaround, that would benefit all users.
Fast rendering, at least a lower quality one should be available right at your finger tips, not under your toe nails smile
Charlie, you are always helpful, but I feel this has to be dealt with on developer level, not on user end.
P.S. The tune of yours that brought fruit after many years, still rings in my head. Beautiful!

Matt,
"BIAB already does have a setting to begin playing while regeneration continues in the background. Perhaps you turned it off if your machine is slower or you had problems in the past?"

I am confused... where is that setting? I have the "fast boot" turned on and "speed up regeneration of RT" set to high... But I do not believe it has to do anything with "begin playing while regeneration". Please point me to the right direction.

Thank you.
