it looks like a contact hardware problem when Midi off on c3 is not working and Midi in works with high velocity only, except that the problem follows octave plus or Octave down to C4 C2 etc.
I have deleted the Komplete Kontrol files in application support ( I am on a Mac ) and:
In standalone -> NO problem
In Nuendo -> NO problem
In Logic -> Problem….
Anyone here with a solution ?
Thanks
