Thanks for the link. I also had interpreted incorrectly. I was originally under the impression (incorrectly) that the MIDI was what was doing the stuttering.

Q1:
I'm presuming that the song plays OK as long as you don't play anything on your keyboard. Is that correct?

Q2:
Have you tried a "Return To Factory Settings - ALL", from the Options menu? (I can't recall above if that's been suggested). You would have to then reset some values.

Hello again AudioTrack,

I now have the answer to your question 2: I tried to return to all the factory settings and ... it does not change anything: Band in Box 2025 still stutters when I play normally on my piano with the MIDI Input Driver activated!

But the return to the factory settings caused something new that I can not explain: in the mixer the realtracks are indicated as unavailable **N/A** (screenshot 1 below) while their location in my computer indicated in the Preferences/Realtracks is correct (screenshot 2), that the folders exist in this location in my computer (screenshot 3 for the bass Realtrack), and that they are played by Band in a Box!

Another mystery :-)
