[sdiy] Roland keyboard problem - one note keeps playing at full volume..

[Oakley Sound]

Standard problem on many keyboards that utilise two contacts for sensing 
key velocity.

On Rolands its usually good enough to remove the rubber key pads 
completely and clean both the contacts on the key pads, and the contacts 
on the PCB.

Use Isopropyl Alcohol on a cotton wool bud and make sure you get rid of 
all the dust too.

You can replace the whole rubber keypads if this doesn't work. Roland 
normally have a good set of spares.
