ALK2 has an amazing loop record feature where you can set a record region followed by a play region which repeats the recorded loop for however long you need. Plus you can have multiple different recorded loops on the same track with all the playback regions switchable to refer to any of the previously recorded loops. So instead of just extending a loop continuously there can be gaps of silence between the playback regions. It's much easier to see it in action than explain.
It's a shame that the ALK2 interface is a bit clunky.
But this would speed up the loop recording process massively.
