Power Piano is a new high quality piano voice made for Yamaha Genos, Tyros, PSR, and Korg Pa arrangers.
Although internal piano voices from all modern keyboards sound good, they are no match for a high quality sampled piano sound as Power Piano.
It is sampled with 6 velocity layers, and with each sample sharing only 3 keys which counts 174 individual stereo samples in this great piano sound.
Not only that, but each Power Piano sample has natural sustain up to 7 seconds long so it does not sound cartoonish, nor synthetic as internal piano sounds from all modern keyboards.
Power Piano comes in few sizes depending of the keyboard model so it occupies minimum 60 megabytes for Korg and 120 megabytes for Yamaha.
