The Yamaha P-45 is an 88-key digital piano with Graded Hammer Standard (GHS) weighted action. The keys are heavier in the low end and lighter in the high end, like the hammers inside an acoustic piano. The black keys have a matte finish that is less slippery during long playing sessions.
Its sound comes from AWM (Advanced Wave Memory) Stereo Sampling, which records an acoustic piano with two microphones. The P-45 plays one sample per key at varying levels of volume and timbre. Besides piano, it has electric piano, harpsichord and strings voices.
The P-45 is slim, with a depth of less than 12 inches, and weighs 25 lb. Built-in speakers let you move it around the home or use it outdoors. Many settings are changed with a single button: hold the "GRAND PIANO/FUNCTION" button and press the keys to change voices, play demo sources, set the metronome and more.
