i'd like to know why you can't set the volumes of FILLS without having it changing the volumes of the Arranger parts A,B,C,D respectively.

can't choose a different kit, can't choose different volumes, can't have different FX for Fills & Arranger parts

seems FILLS are tied to arranger parts (kits, volumes, effects, etc)

BUT BREAKS are independent

i need to be able to set my FILL volumes, kits, FX independently

this is beyond incomprehensible...
