That is normal with the Yamaha driver, and you will notice it in other software.

And now that I've set my Clavinova CVP 307's MIDI to Master Keyboard, I can use Band in a Box 2025 with the MIDI Input Driver enabled without any stuttering issues.

So, I consider the problem raised by my initial question solved for me 😊!
Glad you found an acceptable solution!

Was this done?
This is normal with the official Yamaha driver, as there are multiple MIDI "ports" on some devices (My S90 has eight, with only one device in Device Manager).

I agree.

Definitely bad.
I also agree.
