I want to switch between Set List Maker and Loopy Pro either by iPad onscreen buttons or via MIDI controller. I have added a SLM Layout button with URL scheme that launches Loopy Pro, and that works correctly. What I am trying to figure out is how to switch back to SLM from Loopy Pro.
Clues: Loopy Pro will allow me to create a button send a MIDI Message directly to a Target (Set List Maker, for example). I can send a PC, CC, Note or Hex message.
I also don't understand this from the SLM manual: "To return to Set List Maker after jumping to a different app, you can use the "Back to Set List Maker" button that appears in the top left corner." I don't see such a button anywhere after I jump to Loopy Pro.
What can you think of that I might try to switch back to SLM when it is running in the background?
