I got a brand new Komplete Kontrol S61 MK2 keyboard. Out of the box, I've been experiencing some rather minor, though noticeable issue. When I play certain keys especially in the lower register and some of the top notes, there is a buzzing/springy sound coming from the big encoder knob. I think what is happening is that when I play those keys, it vibrates the whole keyboard/chassis in a certain way causing the encoder knob vibrate as well (sort of like when you lightly flick a spring door stop).
Is this normal? Anyone else able to reproduce this issue on their S61s or other S-Series keyboards?
