Fluter:
Yore welcome ..always glad to help
another trick to try on a tag turnaround like:
IImi7 V9b III mi75b VI 9b IImi7 etc ...
is to substitute for the last two changes:
IImi7 V9b ( III 7/13 ..bVII13 /11# ..IIImi7 over VI bass note ..Vi13 9b ).. IImi 7 etc
this works best when the melody note in the tag is the third ....
