Hi,
You can probably do something on the Genos, but others would have to help as I don't have one.
There are no doubt several ways to do this, but I personally rely on MixMaster by Etienne
https://www.psrtutorial.com/forum/index.php/topic,61876.msg474181.html#msg474181In MixMaster, I drop the midi on the app then I use list view to see the notes and the durations. I suspect that you might have a very low (or 0) volume instrument that has a length greater than the end of the penultimate bar. This would cause another bar to be shown. Importantly this might not be in the penultimate bar, but it could be a few bars back with a huge note length. I have seen that a few times. It is very easy to change. Right click and then "Edit a Selected Event" from the context menu.
Alternatively you might just be able to delete the note, but check to see if there are any volume events that reduce over times as you will delete the whole thing.
I have also used notation composer, but found that can give several problems when you make a small change and resave. You can also probably use cakewalk or other utilities, but as I say, MixMaster is brilliant. It is a very powerful tool.
Hope this helps
