In the Track Inspector, if I select the Input Routing box of a Midi Track, a dropdown list of outputs appears. After ‘All Midi Inputs’ it lists two new entries, both called ‘Output 1’. What are they for? - I can not find them defined anywhere in my setup.
Likewise, If I do the the same thing in the Output Routing box, it includes 3 new entries all called ‘Input 1’ - what are they for and where do they come from?
