Featuring an 88-key Graded Hammer Standard (GHS) keyboard, the feel of the Yamaha P-45's keyboard changes gradually according to the register, with a heavier feel at the lower notes, and a lighter touch at the high end. The natural feel of this keyboard provides a genuine piano playing experience that is remarkably close to that of an acoustic piano, down to a matte finish on the black keys.

AWM is a technology that uses digital recordings of sources, like real instruments, and allows players to enjoy grand piano reverberation wherever they may be.
