Import woes (again)

[RJVB]

I've have some acceptable results with Audiveris over the past years, importing really simple score that I had cleaned up a bit, so I tried a scan of an old (out of print) score. Not surprisingly that didn't work at all, so I tried two much simpler and cleaner scores, compositions by the late Michael Chapdelaine.

These too fail hard enough that I can't use the result in MuseScore, in part because most if not all triplets go undetected (and MuseScore can't seem to correct that).

It seems that fingering indications are part of the problem, too.

The Chapdelaine compositions are freely available from his website so I think I can attach them here. I'm not certain about the other score.

Are there tweaks that I can apply to get a more usable result (= one that doesn't require more time than entering the entire thing from scratch)?
