in the German "Musiker-Board", the question arised a few day ago whether there is an "Auto power off" function on the Motif XF or not. A user bought a brand new Motif XF7, and the device automatically powered off after half an hour or so when not playing or programming. He reported being able to resolve this by pressing the lowest key while switching on his Motif XF7 (as it can be done e.g. on the MOX)...see his picture with the "Auto power off disabled"-message on the Motif XF screen in this post
Other users (including myself with my XF6 and the same OS version as shown in the second picture of that post) were not able to replicate this behaviour or to turn on/off "Auto power off". Might it be possible that this is a "new" function being introduced in recent models (e.g. due to EU energy-usage regulations, a conjecture formed by 5pinDIN on Motifator), or does anyone (Phil?) have other ideas?
