OM, you are being very king and helpful, as always, but... you are way off the mark with this one. (respectively said).

The OP wants to use the BIAB features for MicroChords. You know that feature that allows you to place chords in a bar at 1/16th note resolution. It was one of the new 50 new features from years back now. In the F6 menu it has a selection for "triplets". Triplets are not something the OP hears in his head, it is a well defined sound and understood form of notation and playback. But the Micro Chords is NOT playing the chords in this manner.

What you are giving us is a "workaround". Which may be fine. (BTW, I tried to DL you version using midi in the piano roll, but that site you use for storage tried to DL other software along with your file!! - Please git a google account and use the free Goggle Drive like everyone else.

So I can't listen to your file to see exactly how effective your workaround was.

I feel the OPs challenge should remain open until Simon gives it ago and either shows us how it is done or acknowledges it is not working .This thread is NOT resolved.
