I have a new Kontrol MK3 and I have 2 main issues.
The first one is that, sometimes, the daw integration will not work and every buttons on the keyboard are useless (can't loop, record, or anything else). The only and annoying solution I found is to shut everything down and delete com.apple.logic.pro.cs and com.apple.logic10.plist, which force logic to analyse every plugins on my computer at the next session. This problem appears also when I restart the midi keyboard in the middle of a session.
The second one is, when everything is working, at the start of a new session, the Quantize button is automatically triggered and I can't take it off.
Everything is up to date, and correctly set up.
