Reply to Sticky button on Midi Fighter 3D :(

Hi there,

I just received my Midi Fighter 3D in the post and one of the buttons sticks for 2-3 seconds before releasing and when it releases I get a slight static sound from the way the audio cuts on what I am playing which is weird as its just midi signal.

The light stays on to confirm its held in place for this time and it then does the animations which is usually instant on the other buttons.

I have logged a support request, but in the meantime has anyone else experienced this?

Any fix? or is it faulty?
