When I add a main chord, these vibes play perfectly on the original and copied notes (unfreeze first!):

Thanks for that info about the 'main chord'. I did originally have a 'main chord' at the start. But when the micro chords started playing back in a 'wonky' fashion I started to experiment.
I thought the transparent chord (main chord) might be the reason it wasn't working.
I soon discovered I could delete everything in the bar and then add the micro chords and have the
'main chord' disappear. I thought this was a good thing!

Anyway I put back the main chord now and this is what happened.
On the first pass the micro chords played (not the best voicings though).
But... on the second pass I got a triplet feel on the first two chords and (2) 1/16ths , 1/16th rest and 1/16th note on the second beat (three chords instead of two). So back to 'wonky' (buggy) chords.
