You are right about the 1x display. You can empty the loop but it is not very practical in a live situation if one can not see on the display what's really happening. I always use the H9 control on my laptop also when playing live
The most practical situation would be where you want several bars (or an exact time) of loop that you don't need to play immediately immediately but want to trigger later in a song.
ok, but then it would be more logical to me if the behavior was the same when using the footswitch to stop the loop. So not only with the loop end time like it is now.
