Only receiving MIDI "release", not triggering.
Firstly I am using the Komplete Kontrol S61 midi keyboard, which one day mysteriously began acting this way.
I am having an issue where the C4 note is not getting triggered, the only message Logic displays is its release. Every other note works perfectly. On and Off trigger flawlessly, except with C4. This is not a hardware problem as I can transpose on the keyboard to a different octave therefore triggering C4 using a different physical key, however no "on" message ever gets processed by Logic, only the "off" or "release". This note works just fine in other applications/DAWs.
Is there perhaps a configuration that can block the "on" signal?
I have spend hours on the preferences looking for a solution, anything from changing the MIDI bandwidth to a higher percentage, deleting and resetting all the configurations for control surfaces amongst other things. I can't seem to find a solution or a similar problem online, any suggestions are greatly appreciated!
