Hi Charlie
I have just loaded your midi ITS.MID to the melody track in BIAB and it plays fine.
And generates a chord sheet tempo is 169bpm
When I look at track 2 ch 2 in Sona
The 2 cnt events at the start of the are RPN pitch bend Sensitivity and
cnt 5 portamento time. As this is a tenor sax track I would say that they are required for the correct sound
