Hello.
I have a problem. With a certain combination of keys, when they are pressed simultaneously, not all notes work. The key of the note E of the next octave does not work when the keys C, G are pressed simultaneously. With other combinations, the note E works. Similarly, with D, A, F#, the note F# does not work. This can also be seen on the Midi console in the Midi Control Center. Drivers installed latest. I understand that the problem is not in the mechanics of the keys. How can it be cured.
