Thanks for the warning notice! I download everything in Linux, and scan with ClamAV there, then scan in Windows 10 with Defender. But I admit to slacking off on these habits. Thanks for the little kick in the rear.

Please keep people like myself updated on your experience with Denemo. I haven't even had a chance to install it yet.

As for Band-in-a-Box, up to now I've only used it for creating accompaniments for my sister, who because of the pandemic, hasn't been able to find a community band in her area. Her flute practice was suffering, and these cool backups I provide via Band-in-a-Box are in music styles that she admittedly enjoys more than the bands ever provided.

She and I have also been working on some children's book ideas of hers, of which I'll provide imaging from my 3D software. So I've been very busy. Hence, I am frustrated over not learning Band-in-a-Box as fully as I had hoped.

Denemo will hopefully be a good way to quickly get the notation created, better than MuseScore, which frustrates me beyond description. So again, your experience with Band-in-a-Box combined with Denemo could be a valuable source of info for the rest of us.
Thanks for your response!
Cheers,
-Ken
