Some good and bad news.
Good news are that I managed to had an infamous “stuck note event” while in rehearsal, in a cellar of a friend’s house.
So I had time to investigate a little and be sure of my actions.
When I play live, my rationality does not work at all.
It was with Arturia KeyLab mkII 61 keys, my notebook Asus, my Kontrol Audio6 board, while playing some excited organ chords on Hammond B3X.
No way to stop the note with “Panic” command (three push on the STOP button of the controller, or push on <!> on C3 screen), the only way was as usual to play the stuck note again. So the controller inside KeyLab was again in serious troubles.
The only difference between yesterday evening and my previous experience were new USB cables I bought on Amazon. Here a pic of those new mates.
It is the best I could find, nothing good in electronics shop, no other way on line.
See the magnificent “golden coated” plugs…
Bad thing is that in Europe cables do not show AWG rating, so I cannot be sure of the thickness of the copper.
Here are two cables, one by Ugreen, one by Amazon. First one was under test yesterday.
So evident conclusion was that cable is not the guilty device.
Next step will be to be sure of USB electrical rating.
As an electronic engineer I cannot exclude that in some circumstances notebook is not feeding properly (with correct current and tension) the keyboard power need.
So next device under test will be a new active USB hub like the one here below.
Now my opinion is that all the friends here are right.
I am looking for a decent power supply for the Arturia controller too, to drive it with an old MIDI cable. That would be probably the solution.
Of course if active hub and power supply will not work, I will sell this keyboard, trying to find a better one.
Stay tuned for the next episode of this saga…
