Komplete Kontrol transport controls crashing. No support received

Transport works fine for me in Logic. Having DAW port selected is not the issue.

For Live, it does say to use the DAW port.... for Control Surface selection. What people should NOT do is then select that same DAW port as a MIDI Input as it is for control signals and not MIDI input signals. I am not 100% sure on how Logic works with the DAW control but the DAW port is not a standard MIDI port, more an MCU control port and same thing with an MCU, if you select it as a MIDI port you can end up with notes/signals being transmitted into your project when you press some buttons.

It is usually the reason people experience things like hearing their synth play sounds when they use transport, random start/stop of the DAW, track navigation either not working or ransomly stopping, no feedback to the keyboard for things like mixer mode, failure to auto-select an instance of KK when switching tracks. These can all happen in Live so I assume issues can also arise in other DAWs so as rule of thumb, just test without that port selected as MIDI input.

Reading this..the problem should be exactly that the keyboard goes automatically in midi mode. And this mode sends for some buttons midi notes messages (which will of course play notes from the instruments).

Have you tried to build a template in Controller Editor telling exactly what kind of messages every button must send? You shouldn’t have to do this, but at least you will be able to use your keyboard.

You build your Own template, select it when the keyboard goes in midi mode and at least like this you know EXACTLY what the buttons send, because it is what YOU chose
