This is another edit of a soundfont I found in Soundfont4U website. Nice mellow sounding piano but gradually gets brighter. I widened the soundfont for 128 keys, fixed some velocity issues, and made it into one single preset. This soundfont has 5 sampled velocity layers, however the samples aren't full 88 single note samples but they are like 2 to 4 notes for each sample. Enjoy.
