do i only save this for the slot then, or is this setting always limked to the sample.
by reading my question i understand the latter is correct 
Exactly!
Different is for Recorder buffer.
The slots named RECORDING 1—8 retain those sample settings since you can think of them as they are actual samples.
Sure enough you can pre-slice those slots (if you are -or- will be on the same bpm displayed besides the name)
