Hi! I have a PreSonus 1824 which is my main audio interface. I also have a Roland TD-50 drum kit. To record the individual snare, kick, cymbals, etc. via the TD-50s USB to Studio One, I need to switch audio interfaces from the 1824 to the TD-50. I do that (change audio interfaces), open a saved IO configuration for the TD-50 so the channels map correctly (using Song Setup). When I do that, however, any tracks that have been recorded via the 1824 lose their input mapping (i.e., they go from Front Panel 1 to None). Even when I restore the 1824 as the audio interface and reload the mapping for that device, they all stay on "none" for input. Am I doing something wrong? Thank you!
