Midi Import ignores slides
While the midi import function has still some problems, most of them are cosmetic, like only detecting half of the triplets. But the biggest problem is that it doesn't detect any of the articulations the midi does with the notes (slides, blends, vibrato). While it doesn't matter most of the time, there are some midis where it can change the melody, because a note starts below or above the intended note. The given midi (Battle! (Giratina) - ripped from a Pokemon Platinum rom using vgmtrans) is an extreme example of that.
I hope this will get fixed in the future.
