That's so good, so professional what you have done, you have obviously gone to a lot of trouble. I don't know if you could do all that in the old Delphi as it seems to be just old grey dialog boxes/windows with check boxes and standard buttons.
I think that would be a lot easier with JUCE UI programming as Adar seems to implement things in the Plugin UI quickly and with professionalism and quality.
I think PG is a a pivotal moment where it needs to take some big steps for a whole new audience, maybe keep an old legacy version for the old users and a quantum leap version for new users that is crossplatform OS Standalone/VST

It's just so good to see users with insights and ideas to take it a leap forward where it belongs as we all love Biab because of it's end result but to be able to do it in a more professional modern way.

I'm worn out now from all that I have been through and really don't know how much longer I'll be around as things are a bit dire at the moment, so I give as much as I can that may help things go into the future and last long after I'm gone.
Peter like me must be getting on now and has come a long way with it, but a big leap now would be great to see for all of us, Biab does deserves being sustained into the future ! Forget AI, use or own God given creativity with these great session players.
All I can say is you have great ides and to keep at it and don't let anyone put you off !
I'm sorry if I get stressed out, just been through too much and been through it all too long frown
God Bless.
