I believe at present that if you want to tap in a tempo you have to use (Tap) in in the menu which means one has to hit the footswitch to access the menu, the use (Tap) to tap in the tempo and then use the footswitch to Exit the menu.
It would be useful to have an option to be able to tap in the tempo without having to go through the menu. Maybe something like if bpm=0 then the tempo can be tapped in. If this is already possible please let me know. I have gone through the manual but not found anything.
 I realize that the Exit in the menu signals that the tempo setting is complete. Maybe something like an elapsed time of ~2 seconds with no activity on the switch or pressing another switch could serve the same purpose.
