That is a lot more info, but we already answered your question.

That new "aligned version" sounds exactly like "tempo mapped". Meaning a variable tempo. As I said BIAB will not use this. But the the "quantized version" is a conventional fixed tempo and can be loaded into BIAB via "File-Import-Import Chords from Midi File (Midi chord wizard) in order to fill the chord chart. If you want to bring the midi notes over then you simply need to Drag and Drop the .mid file into BIAB chord sheet.
