Ahahah!! But I was joking, I thought it was clear! An army technical manual dated 1954.... The "definitive solution"... But I'm sorry if it wasn't clear enough, my fault.
I have a question for you all: how do the sensors work?
Are the contacts in the rubber strip ON/OFF contacts? If yes, how does the piano feel the "touch", the speed, to play piano/forte?
The reason of my question: my issues are with 6 keys, but only black keys. I saw a lot of people having problem with black keys too. A strange thing, because for dust and moisture all the contacts are the same ... So i'm asking himsel if there is another kind of problem.
