Btw, I can do the text conversion with a macro in Notepad++ , that's quite easy now I've figured out the format. All but the short duration, <1/4 note chords which I just remove them via the macro and they can be filled back manually after import.

Because the txt output from SMP is not consistent with short chords, I doubt PG could implement the conversion.
XML output from SMP, on the other hand, seems all fine. So the easy fix here is for BIAB to fix the XML import and export for what they call microchords.

I can give a lot more detail with my findings if it helps any but I won't bother posting that unless you ask because it will be a long boring reply smile
