Many people post in the forum they upgrade for the content (RealTracks, MIDI SuperTracks, etc.) more than new features. If that's how you feel then yes, it's worth upgrading from 2021 BiaB Ultra PAK to the 2025 BiaB Ultra PAK. If not, then the Pro PAK maybe the best option for you.

Band-in-a-Box still prefers 44.1K sample rate and 16 bit rate.

After saving and regenerating a song, BIAB doesn't always play back any changes to Styles correctly.
This is a subject best separated and placed into a new thread. There is the potential for lots of follow up questions, responses and opinions.

I gave up trying to use repeats/2nd endings, etc. years ago.
Repeats/2nd endings etc. hasn't greatly changed. Again this is a subject best covered in a separate post as there will be lots of follow up questions, responses and opinions.

Four years of change is a lot of change. I can attest 2025 Band-in-a-Box is more stable and crash resistant than 2021 Band-in-a-Box.
