PROBLEM AND SOLUTION.

Let me introduce it this way please just to
get this topic going.

PROBLEM
Hearing piano for one, out of speakers,,,, is not the same as from a real piano cuz of the sound is coming from inside. Shielded and you hear more of the room sound. On your keys, you hear speaker sound directly in front of your ears.

SOLUTION
Shield the speakers with cardboard or other material using a tilting shield like fin.
Or set keys into a corner. Kitty corner and cut cardboard to fit from over speakers and into the corner. edit brightness etc... and you have a real piano and organ sound! You hear the room sound. Feels and sounds like you are at a real piano!
YOU CAN MAKE A LIGHT WEIGHT FIN AND ATTACH IT VIA THE MUSIC STAND HOLES. USING SOME SMALL TUBE LIKE METAL AND THE RIGHT SUPPORT BRACKETS FOUND AT HARDWARE STORES.
