Similar to other developing technologies, digital pianos are also one of the technologies which have drastically improved and developed over the last few decades far more than the traditional acoustic pianos.
- Keyboard Functioning
The main thing in a piano is the sound and rhythm it produces and digital pianos are made considering both of these factors. The keys are electronically programmed to produce a sound the same as a traditional acoustic piano would make. It is done by recording the sounds of a real piano and program the same in computers of digital pianos. In digital piano, this sound is produced with the help of a computer installed inside and weighted keys which take some time to raise back after pressing due to weight.
You can say it is very much similar to laptop keys where a signal is sent to the processor whenever we press any key. It also has some advanced mechanisms to create an effect of playing a real piano. Some advanced digital pianos also have the key with hammer feature for playing sound but the keys are still weighted to respond more like a real piano.
- Sensors Operations
There are some sensors installed in a digital piano which interprets what your fingers are doing on the keyboard. After that, a signal is sent to the computer to produce the corresponding sound for whatever key is pressed. Also, there is a series of sensors attached over a keyboard which senses the different features available in a digital piano. For instance, some sensors can only transmit three or four bands of touch velocity while others, when used in multiples, can accurately interpret thousands of touch velocities.
- Speakers Functioning
Speakers are the most important part of digital pianos having the most of control over the tone of the piano. It is not same as a traditional piano where higher wattage is corresponding a good sound quality instead it will only produce a louder sound in a digital piano. While the overall fidelity of speakers is what matters the most in digital pianos which is responsible to make a difference in how realistic sound can be produced by these pianos.
It also decides how much frequencies it will cover from a broad range of booming bass strings to delicate treble notes. With growing technology, engineers are trying their hard to exactly replicate the sound of that traditional acoustic piano with smarter computers and faster developments.
- Paddling Action in Digital Pianos
There are actually damper pedals in a traditional acoustic piano which are used to connect the sounds of two strings as otherwise, the sound will have a breaking effect after each key is pressed. Though some digital pianos also have pedals the advanced ones follow a new technology named as Progressive Damper Action. It helps in creating the effect of damper pedals by controlling and connecting the two sounds made from different keys.
There are two other pedals also which too used to control the sound but these two pedals are mainly responsible for softening the tone and controlling the volume pitch of the music.
