"Could I do something to push priority of your solution higher in the PGMusic to-do list?"
I have been pushing very hard every day for the last few years to get it all working good frown so hopefully soon.
You can drag the track from the Mixer in the main Biab app onto the track in the Biab VST, as it is easy in the main Biab to regenerate sections.
If you want a track that is dry, flat and center drag it to the "+" in DROP export.

Yes, planned for sometime in 2023.

Sync with any decimal varying tempo map.

We plan to add support for floating point tempos and any time signature, in BiaB, plug-in, and RB.

>Go over 255 bars.

Yes, planned for BiaB & plug-in. Already possible in RB.

We have source wavs for this 24/48, and are looking into it. This I will take time, but should be worth it.
