In piano lingo, “action” describes the way the piano keys feel when you press on them. With a digital piano, the closer the action is to that of an acoustic piano, the better. Semi-weighted action uses a spring to create the resistance felt when pressing a key and its rebound when you lift your finger. Hammer action uses a hammer mechanism like that found in an acoustic piano to replicate the feel. Graded, or progressive, hammer action takes that a step further by increasing the weight of the action as you descend to the lower notes on the keyboard. Using a keyboard with weighted action is beneficial for multiple reasons. It helps build finger strength while practicing (a spring-based action will only minimally address this), and it allows for more variation and musicality in the way you play a note. While a piano keyboard might look like nothing more than a bunch of on/off switches, in reality there’s a range of volumes and timbres that can be achieved depending on how quickly or strongly you depress the keys. Hammer action best replicates those possibilities.
The snare drum is the heart of the drum kit, particularly in rock, due its utility of providing the backbeat. When applied in this fashion, it supplies strong regular accents, played by the left hand (if right handed), and the backbone for many fills. Its distinctive sound can be attributed to the bed of stiff snare wires held under tension to the underside of the lower drum head. When the stiff wire are "engaged" (held under tension), they vibrate with the top (snare-side) drum skin (head), creating a snappy, staccato buzzing sound, along with the sound of the stick striking the batter head.
In general, the sounds produced by a digital piano are based on sampling, by which real piano sound samples are stored in ROM. The samples stored in digital pianos are usually of very precision recording and made using high-quality pianos, expensive microphones, and high-quality preamps in a professional recording studio. ROM may include multiple samples for the same keystroke, attempting to reproduce diversity observed on the real piano, but the number of these recorded alternatives is limited.
Combining rich acoustic sound with modern music technology, digital pianos are sophisticated instruments that are played and favoured by professionals and amateur musicians around the world. More lightweight and affordable than full-size grand pianos, today's digital pianos sound so close to their classic counterparts that untrained ears would have a hard time telling the sound produced by the two apart! In this section you'll find a wide variety of home and stage digital pianos from all the big brands. Yamaha, Suzuki, Roland and more, they're all here, so if you're in the market for a digital piano that was designed to perform, you're definitely in the right spot.
