Unwanted key change

Elektron Gear Digitakt
#1

Hey folks!
I am using the digitakt to sequence my minitaur.
Every now and then it totally messes up the key of the sequence after I turned it off and on again. Untill now I just rearranged it by ear but after turning it off and then on again the minitaur is out of key by 3 semitones.

Any ideas?

i booted the newest firmware, since that i did not experience the problem anymore, eventhough there was no known problem like that in the bug fixes, but thanks all!
