Ozzbox33 hi Ozzbox33 , my advice to you after being in your situation already if you plan to use ST3 being a very powerful tool is get a foot pedal with more buttons as you mentioned you already want 2 actions , well one of those actions take 2 switches already like selecting next song you need up/down movement then you have your must have stop/start that’s already 3 buttons so already 2 buttons aren’t enough if you use looping that’s another 2 buttons that’s 5 already you can get a six button pedal AirTurn that is really quiet compact and easy to use which will easily provide you most basic needs, ST3 is so powerful with great foot control features as a simple user like myself I feel like I still want to buy a second six switch pedal because having everything at your feet feels so good on stage it’s a lot more professional as you rarely need to touch your device, I also use tempo change and audio mute to great advantage and volume up/down there goes nine switches with basic bread and butter controls , so my advice would be if you can return your device and buy as large foot pedal as you can find and so far six switches is all I have found.
Good luck Damir
