Hi
I found a way to be able to use 6/8 time signature midi imports with 4/4 styles, the approach is that the midi have to be edited in 4/4 time signature with sextuplets arrangement, see image below/attached for an example of a normal 6/8 arrangement, and the required translation into sextuplets arrangement.
It works fine in BIAB with 4/4 styles...

It needs some additional editing to get the sextuplets arrangement but in does the trick to be able to use 4/4 styles normally. Allows to place chords at beats 1 and 3, I guess that to be able to add chord on each beat, then a more elaborate tuplets arrangement should work too, e.i. twelve tuplets to allow for chords into beat 1, 2, 3, 4, ...
