I recently purchased a GW-7 keyboard and I am generally pleased with it. The only problem I have which can be quite annoying sometimes is that it misses playing the sound when striking a key, in a totally random fashion.

I wonder if somebody else has this problem? I tried looking for a system update at the Roland site but there doesn't seems to be any for this particular keyboard.

Apologies if this has been discussed before. I tried searching the forum with no results on this subject.
