Hi.

I noticed that there are a few keys that produce noticeably higher velocities than others when 
struck in a fairly consistent way, and I think it's bugging me. Is there a simple cure for this 
(like cleaning) or does it need to visit its makers? Could dirt be stuck there and be causing all 
this or is it something more serious? How does the velocity sensor work, anyway? Is it an 
actual key velocity detector (like on Fatar keyboards) or just a pressure sensor?

Also some of the keys in the vicinty of those with weird velocity responses smack the front 
plastic lip on the front when played with only moderate force. Wonder if that's related.

Thanks,
Alex
