Yamaha's GHS (Graded Hammer Standard) weighted action has heavier touch in the low end and lighter touch in the high end, just like the hammers inside an acoustic piano. Great for the aspiring pianist, practicing on the GHS action builds the proper finger technique for when the time comes to perform on an acoustic piano. Plus the matte finish of the black keys are less slippery when playing for extended periods of time.
AWM (Advanced Wave Memory) sampling uses digital technology to record the sound of an acoustic piano. AWM Stereo Sampling creates a deeper, richer and more spacious sound by using pairs of waveforms (L and R) captured with two microphones. The P-45 uses AWM to play one sample per key at varying levels of volume and timbre.
Various P-45 settings can be changed with a single button. Hold down the "GRAND PIANO/FUNCTION" button and press the keyboard to change Voices, play demo sources, configure the metronome and more.
Auto power off shuts down the instrument after a period of inactivity. You can customize how long it will wait before shutting down, or disable it if you prefer. To learn more about other ways that Yamaha conserves energy, visit our Corporate Social Responsibility page.
