Default Re: MIDI keyboard fault

I use one of those fibre glass brush 'pens' for the same kind of thing, polishes IC pins up nicely.

One reason those sockets are such a menace is that the IC spends its whole life exerting significant pressure on the insides of the socket but there is nothing exerting equal but opposite pressure on the outside of the socket, so, over a very long time, the sides of the socket tend to bow gently outwards, away from the IC, especially in the middle of each side.
