Doepfer

Hello,

I have a problem with one of my A-190-1
until this morning everything was fine, but this afternoon I wanted to work on a composition and followed the keyboard is no longer
do, re, mi, fa, sol, la, so, do (C, D, E, F, G, A, B, C)
but there are now more or less a fourth interval between two notes;

So instead of having a C, D .......
rather it is C, F ......... and even the tune is not just super!


Can someone tell me what is happening and how to fix it?


thank you
