If you happen to be an owner of a Korg Pa4x/3x/1000/700 model I have released a free 6 velocity layer piano based on the Creative Commons Salamander Grand. This piano has resonance , pedal (including 1/2 pedal) and key-off effects for a highly detailed and expressive sound. Free to download from the links in this YouTube demo.
