Thanks but as suggested by previous user Noel, I'm now using Realband to be able to go beyond the 255th bar, while your screenshot is from BIAB.

And yes, you're both right, 3000 bars is ridiculous! But I don't read it all in one go of course! wink
It's just convenient to have as much as possible in one unique MIDI file so I don't have to load lots of different ones.

This is how the Notation Option menu it looks in Realband vs BIAB. As you can see, I don't have a Bass clef setting to disable:
