Having had a couple of weeks where things have been ok, the disappearing and/or non-functioning bindings problems have resurfaced.
I made a set list of just 5 songs, two of which are new, and everything worked fine, so I closed the laptop down. But next day when I went back for a practice, non of the bindings would work, even though they were all showing. The bindings are all in the background rack.
So I deleted them all, and re-programmed them in, and everything worked ok. So of I go to band practice, set my kit up and the bindings have stopped working again. There wasn’t time to re-programme them all, so I had to scrabble around changing them by hand.
I shall arrive early on Sunday and redo the bindings and then leave everything switched on so at least things will work at least once.
But I am baffled as to why this keeps happening, and why sometimes it actually doesn’t.
