The reason is that I use external microphones to record acoustic instruments. Since the footswitches produce a very loud “click” when depressed, that click is recorded along the acoustic instrument, and can be head in the loop itself… and repeat itself with the loop. If you work with 6 tracks, you start hearing x6 clicks looping… it destroys the experience.
Solution: allow the labels at the bottom of the touch display, to work as silent switches. Instead of using the footswitch, just touch (silently) the respective info-label to activate the start/stop/overdub actions.
It is an important feature, when working with acoustic instruments and microphones in a room. Thanks for considering this for a future update.
