Thanks for the quick response. Yes I understand playback, but according to the manual on page 133 you can also assign recoding buffers:
Any recorder buffer can be assigned to any track. To make it easier to remember the recorder buffer track assignments, it is recommended to assign the recorder buffer to the track whose track recorder will be used when sampling. For example, if the track recorder 1 should be used, assign recorder buffer 1 to track 1.
So I just don’t see how to this!
