3. Operating Instructions
Familiarize yourself with the various functions and features of your NPK-10 digital piano.
3.1 Key Action
The NPK-10 features 88 full-size, scaled hammer-action keys with triple-key sensors. This graded hammer action provides a realistic piano feel, with keys being heavier in the lower register and progressively lighter towards the higher register. Five velocity curves allow you to adjust the touch response to suit your playing style. The white keytops are textured to simulate real ivory, and the black keys have a matte, non-slip surface. A simulated key escapement further enhances the authentic piano playing experience.
3.2 Sound Quality & Voices
The default stereo grand piano sample offers a mellow tone suitable for contemporary, pop, and jazz ballads. The NPK-10 includes a total of 12 voices, such as Electric Piano, Organ, Harpsichord, Synth, Acoustic Bass, Strings, and Koto. You can adjust the tone brightness to match different musical genres. Voices can be layered and split across the keyboard, with adjustable volume mixes for each layer. The piano boasts 189-note polyphony, allowing for complex musical passages without note dropouts.
