I'm now waiting so long (to my taste) to get this sorted out. I wrote at least two support request explaining what was happening and no answer to it. This is very frustrating after having bought a new keyboard. So I get the update screen on my KL61. THIS is OK. But the problem is that as soon as I unplug the KL61 (which has been previously recognized by MCC with 1.19 firmware version), it disappear in AudioMidi config. and when I re-plug it i creates another peripheral in AudioMidi that isn't named KeyLab61 and therefore is not recognized at this step by MCC : therefore the error message labeled in the title of this subject. Can this be solved please !!!
Also, the presets saving doesn't work with KL61 : I do the config in MCC then send it to KL61, then try to save it in KL61 via "Edit/Store" procedure choose any of the eleven presets available let's say 01 (or any other else) confirm by clicking on value button. when I try to recall it, nothing of my config has been saved...
PLEASE PLEASE, HELP NEEDED !!!
