what do you mean the presets? you mean the "projects?"
there's a way to change the jog mode from "kit" to "project"
i forget how though because i did it almost immediately after getting the spark and never looked back
"and just so i have this correct, I cannot have the Fx pad assigned to just one sound,ie the the filter section or the slicer, I have to have it going over the whole project?"
no, that's exactly what the roller is intended to do...you just keep pressing roller until it says what you want to change (filter, aux send, etc) and it will only effect the selected instrument...otherwise no. but not sure if you are aware the the roller can control the filter and such
have you read through the manual?
