I use Studio One to play Click- and Backingtracks for live Performance. I start a Song via the Remote Software by selecting the right Marker/Arrangement Section in the bottom list with a mouse. More practical for live would be to use the “Commands view” and assign a button for each song. Principally It works that way, but unfortunately it is restricted to 20 markers. The same as in Studio One itself. You can define more than 20, but you cannot trigger them with a key command or a button in the remote software.
