Hi. I am by far not an expert on tis particular topic, but I'll offer a thought that may not help solve it but might help where not to look.

My wife has an even older Clavinova than yours and it works fine into BIAB, although it isn't practical for me to test it now with version 2025. MIDI is such a simple signal over a slow serial port that I suspect that is not the problem here. The structure of MIDI signals has not changed in all that time (MIDI 2.0 isn't really implemented just yet). Nor to my knowledge has anything about handling MIDI changed from Windows 10 to 11, as you tested.

If you can get users Gary Curran or RHarv to see your post, that might help. And if it does turn out to be a problem in version 2025, we can alert the developers.

Thanks Matt for your reply.
I am also very surprised that the problem apparently comes from the MIDI signal input.
But I have made multiple tests before realizing that the problem only appeared when I activated the MIDI Input Driver in the Options menu: tests on the PC, on the Windows version, on the keyboard, on the digital audio interface, etc.
In addition, I have been in contact for a month with the Band-in-box support team, and so far they have not found the origine of the problem.
That is why I would be very interested to know if anyone with an old Clavinova CVP (CVP 307/309 or earlier) has already worked with Band in a Box 2025 and whether or not they have encountered a problem similar to mine!
