I have still one question though. If you are able to play legato without the pedal, do you press him?
I have the same piano.The right pedal is your sustain pedal and learning to properly use it takes lots of time. It sustains every note you play until you release it. The middle pedal sustains the first note you play only after you use it. So if you play C E G. C will resonate, but not EG.The left pedal is a damper pedal and is used to bring the sound down of the notes you are playing. This is all explained in the book you should have gotten when you bought your piano.Hope this helps.
The middle pedal is the "sostenuto" pedal. That pedal activates only certain mutes, usually the bass notes. It doesn't sustain the first note you play only after you use it as you've said. At least not on a real piano. It might do that on the Digital, though, but I don't know about that one.
Quote Bernhard in the link to the other thread:"middle pedal - sostenuto pedal. Press a key and before releasing it, press the middle pedal. It will raise the damper corresponding to that single key, which is allowed to vibrate freely - but not the other strings. "Really? What kind of piano are you all referring to? That's not what happens on the Yammie baby grand...? On the Yammie, it only raises the bass note dampers of the first two octaves. So if you play a note above those octaves (like Middle C) and use the sostenuto, you'll only get an echo of that note as the damper of Middle C will have silenced that note but the bass strings were allowed to vibrate.But, what you've described is the kind of pedal action that I've been looking for. And it doesn't exist... does it? Tell me it does! Tell me you are right about that action because that would be great for some pieces which would require it.
So yes, I stand by what I said, except to add that any notes held before the pedal is used will vibrate and not just to one note like I said before.
