after latest update i noticed that pretty often logic doesnt fully recognize my midi controller. When i press a key on my midi you can see on logic what key is pressed but no sound comes out. Also some other small issues every now and then and i would like to hear if anyone else had any problems so i could help myself to understand where the problem really is.

There are always some issues with every point-x update, but I can't find any specific reports of what you describe. Assuming you did the usual hard shutdown/restart, you could try.. - blowing out the Preferences - re-installing Logic If you zipped/saved the previous version of Logic before you updated (as recommended by Apple), you could revert to that and see if that still works. Aside from that, here are a couple of troubleshooting considerations.. - Did you change/update anything else when you updated Logic? - Is this problem fairly consistent (frequently happens) or intermittent? - If it's intermittent, what's common about the times you encounter it (particular song, Instrument, etc)? - Which Instrument(s) are you trying to play when it happens? - Do you see level in the meter(s) but don't hear the audio, or no level in the meter(s)? - Did you check the controller/USB connections, or test with a different controller
