In addition to the normal fill-ins, another line of fill-ins with only one or two user selectable parts leaving the other parts of the variation played unchanged.

I have sometimes wanted to make fill-ins in which only drums and/or bass change but the other parts of the style remain as they are in then current variation. When I use the normal fill-ins to do this it's not only a waste but also sometimes -if not most of the time- I can notice the change in the overall sound even if the same lines are copied or rerecorded.

BTW, I was surprised when I first learnt that PA80 has only two fill-ins while carrying the "Professional Arranger" tag with it.
