Hitting the velocity on that key does nothing. It´s always at full volume/brilliance.
This board was fully recapped and new IC´s were installed in sockets. I will check my soldering following your advice.
In general I have a velocity problem on my keyboard. Some keys are very silent and and some very brutal. But it was like that before I rebuild TSB1, 2 and TKC. I´ve noticed sometimes it is linked to the connectors on the back of each key. Adjusting them a little sometimes helps but in other cases it did not. I am still puzzled about it.
