[Question] Is there any way to have a fixed loop duration before starting to record?

[EricBrunel]

I'd like to record loops of a fixed time, like for example, 4 bars of 4/4 at 90bpm I thought I could achieve that by setting the tempo and the number of 8th notes per cycle, but apparently, I misunderstood. I tried a lot of settings, but I couldn't get the loop recording to just stop after a fixed time.

Is there any way to do what I want? I guess I could bind the 'record' function to some MIDI command, then sync to an external MIDI clock and have the command sent at the beginning, then again at the beginning of the second bar, but that seems a bit overkill. Any simpler way?

Thanks!
