All my custom MIDI templates have disappeared from my KK S49 mk1. I now just have a single template called "Templat1", and pressing the preset up/down buttons doesn't do anything (because there are no other templates).
Controller Editor still shows all my templates, but it seems to have lost the ability to communicate with my S49 (even though it says it's connected). Adding or modifying templates in Controller Editor has no effect on my keyboard.
Does anyone know how to factory reset the S49 or otherwise restore the ability to modify its settings with Controller Editor?
