I have a question. I have already asked the yamaha support, but did not get a good answer. I have an S6 grand piano with the yanaha silent sh system built in. Now playing at moderate speeds is all fine, but I have extreme difficulties playing it fast and piano. First I thought my technique was just bad, but then I played other instruments, and it was much better.
Especially there are passages e.g in Bach’s d minor concerto where you have to repeat one single note quite fast. It is just impossible on my instrument when playing softly. If I do it, the sound disappears or breaks down or you hear every second note. But if you play it loudly, then it is possible.
I had one technician, who tried it and said the touch is a bit hard, but it is ok for practising and it is just a yamaha. I should not compare it to a steinway.
But I think, it is because of this silent system built in and no one knowing how to regulate the action to its full potential without interfering with the system. There is also a metallic bar on top of the action hiding some screws needed for a proper regulation.
What do you think? Have you ever had experience with regulating an action with the sh system to a concert level? Does one need to remove this bar which seems to be very tightly screwed? How much time will be needed to do the regulation?
