Stuck notes

[Furio2]

I just tested with my system.
With all my surprise I was not able to get only one stuck note in 3 hours of wild playing!
I have a new much powerful notebook, so I had to install everything new: all my hosts (Reaper and Cantabile) and Arturia USB driver which is quite new.
To me this seems the most important piece of software, it was alredy getting better, this last one seems perfect.
Then I upgraded firmware of Keylab mkII 61 (1.2.4).
Now everything seems extremely solid, I tried in every way to make my system fail: no way.
I am so happy!!!

Hello,

I get the same issue on my keylab 88 essential. It's brand new and it happens since i bought it. Mainly A3, C3 get stuck, sometimes others. It happens when i play reapeted chords. Sometimes the octabe is olso played, sometimes the 11th semi-tone.
I download the latest update and I use reaper.
I hope it's only a firmware issue.

Thank you

I founds the answer on another forum - this problem is solved by using a powered USB hub. In my case, I connected the keyboard to my monitor usb plug.
