When BIAB shows you chords from a MIDI file, it is because it has figured them out, not revealed what wasn't and couldn't have been there in the file.
That may be true for BIAB but not for the BIAB-VST.
Remember, this thread started with "can not load chords from midi file - In the
BIAB-VST. I do not believe the BIAB-VST "figures them out" as in BIAB when it "loads them". If it did we would not have started this tread. Instead it looks for the chord label, if its there your good, if not you get nothing. I was pretty involved in the initiation stages of this and watched it grow, so I believe I understand it correctly. But of course I do at times get a bit confused by all of this and this threads goes in several directions...
