Hello Ian,

Here's an experiment that might help you better understand what's happening:

1. Create the not1 example again in Composer.
2. Export it as a MIDI file.
3. Don't touch the MIDI file in Band-in-Box(!)
4. Immediately reopen the MIDI file Composer. What does the notation look like? It looks exactly the same as you started with, right?

What conclusion can one make from this experiment?

Cheers
