If you record a part that is already setup as a one shot in a new song, you will be forced to hear it a second time upon ending the recording. It will not automatically switch to the prior part.
Let’s say the one shot is a bridge and you record it on the fly. You press play to end the bridge and now you hear it again!
I can see some situations where the user might want to hear the one shot play immediately after the record, but I think that is the exception. In most cases, it makes sense to treat endo f recording the same and end of the loop (and arguably it is).
