Midi issue

Has anyone ever come across this before?



I’m actually not sure whether it’s my midi keyboard or Ableton, so here goes:



It really varies which key this happens too, but whenever i run my midi keyboard in Ableton i’ll find that one of the keys when pressed wont produce a sound through Ableton.

I’ve tried different plug in’s but it still does it.

Now if i go in a different project then it will be a diff key.

The little yellow box at the top right lights yellow when the key is pressed, even though no sound comes through?



Can’t work out why this happens, bit annoying and could do with fixing it!



edit

Now randomly they’re all working, even though just 2 presses of the same key previously nothing was coming through???
