Good testing, and thanks for reporting back.

I'm quite sure PG Music would appreciate a report with your examples so it could correct this. Send an email to support@pgmusic.com and reference this thread. It could help all of us.

ps a PG Music staffer was not pleased with me when I said here that BIAB doesn't read MIDI chord info (because it's not there to be read) and I think they would like this import function to work accurately, even if it is interpreting the notes to create the chords. You may be onto something about the triplets. However, be aware triplets can be challenging in BIAB. Just because it doesn't look correct doesn't mean the sound is incorrect and vice-versa. In the leadsheet mode you can turn on triplet feel, which is on by default in swing styles but not straight-eighths (what they call even) styles. You can not only switch these appearances, but you can also manually adjust the timing to make rhythms appear correct. And there's quantization... Lots more to try.
