A digital piano is a kind of digital keyboard instrument designed to perform mainly as an alternative to the traditionally acoustic piano, wherein the keys produced a less responsive and quieter sound. It's not intended to be as sensitive as a real piano, with its key actions being arranged to be faster or softer. Unlike an acoustic one, it's built on digital hardware and software making it more compact and light weight. The result is a piano that doesn't have as much key action and produces a more uniform and consistent sound. Digital pianos also have a feature called midi, which refers to the ability for a computer program (or sometimes just a connection cable) to send musical data to an instrument like a keyboard or digital keyboard.
Many digital pianos offer a number of different-sustaining techniques. Sampling is an old digital piano standard, but new ones may include new or old-sampled sounds. Sustain pedals or "pedal steel" are popular on many models. On these, sustained notes are played through the pedal instead of through the keys themselves, resulting in a smoother and less obtrusive sound quality.
Another feature commonly found on digital pianos is the "velcro" effect. This kind of touch sensitivity allows you to play very lightly paced keys. Some models allow you to set the level of sensitivity for this feature. Some models even have additional functions such as alternate notes, treble and bass clef detection, and vibrato.
One feature common to both acoustic and digital pianos is the ability to "overdrive" or produce extra sound from the keyboard. What this means is that certain keys can be made to sound twice as loud as regular keys. This can be great for practicing solo compositions or recording songs because you'll be able to hit the high notes with a bit more force than usual. Unfortunately, this kind of over-singing can also be very destructive to your fingers and other playing senses, so it's important to be conscious of not overdoing it.
The console pong is another useful function for some digital pianos. It lets you play a repetitive chord sequence or piece of music by hitting a series of keys. This is very similar to what a computer keyboard does when you press a key on your keyboard repeatedly. This is another function commonly found on traditional piano instruments. If you don't need to be playing chords, consider investing in a multi-purpose model for ease of use.
The third most common function found on digital pianos is the ability to add additional hardware via MIDI. With this function, you can connect your instrument to your computer and transfer various parameters and software settings. Commonly, you'll find that digital pianos have onboard software that allows you to control your keyboard as if you were playing on a real piano. For instance, you can control volume, bass, treble, pan, delay, reverb, and many other parameters with the simple press of a button. Many stage pianos even have pre-set patterns or songs that can be played back while you wait for other players to join the band. This is an excellent way to stay on top of a performance.
Another important function of any good quality instrument is the ability to produce an accurate reproduction of sound. When you're looking for digital pianos, it's important that the onboard sound is accurate, as well. Acoustic pianos tend to generate a slightly warmer sound due to their construction, but digital pianos will reproduce the sound much more accurately. If you're looking for a great-sounding digital piano, an acoustic model may not be the best choice, as digital pianos often have more versatile sound models available.
One final feature to look for when shopping for digital pianos is what kind of effect you'd like. There are many different effects to choose from, including sampled playback and manual control of volume, pitch, bass, treble, pan, delay, etc. Some people prefer these features over an acoustic piano's more complicated sound models. Whatever your personal preference, be sure to find something that will work well for you. With so many digital piano brands to choose from today, it should be easy to find something that will work for you.
