PIANO SOUNDS

A digital piano produces a variety of piano timbres as well as it is usually with other sounds.

Digital piano are designed to produce sounds of a concert grand piano, an upright piano, a tack piano. In addition, it produces sound of a range of electric pianos, like the Fender Rhodes, the Wurlitzer, and the DX electric piano.

 

A number of digital pianos integrate with other basic “synthesizer” sounds such as string ensemble and   offer settings to merge them with piano.

Usually, the sounds produced by a digital piano are based on sampling, by which real piano sound samples are stored up in ROM. The samples stored in digital pianos are generally of vivid of very high-quality pianos, luxurious microphones, and high-quality preamps. It is to note here that the recording is performed in a professional recording studio of quality, with all the modern facilities.

ROM may contain multiple samples for the same keystroke, attempting to reproduce diversity, which is observed on the real piano.

The number of these recorded alternatives is with limitations.

Sample-based digital pianos sounds are appealing but there are drawbacks. They reproduce the sound of an acoustic piano, which are, sometimes, not up-to-the quality. These might be due to the lack of implementation of harmonic tones that result when certain combinations of notes are sounded, limited polyphony, and a lack of natural reverberation, – when the instrument is played percussively.

They usually are deficient in the incidental acoustic noises related with piano playing, like the sounds of pedals being depressed and the associated machinery   shuddering within the piano. These limitations are experienced with most acoustic instruments and their sampled counterparts. Hence, comes the term “visceral”.

Sustain pedal of both the acoustic piano and the digital pianos are similar.

On an acoustic piano, the sustain pedal lifts the dampers for all strings on an acoustic piano, allowing them to resonate obviously with the notes played. Digital pianos are with similar pedal switch to hold notes in suspension.While, only high-end models of Digital pianos can reproduce the sympathetic resonance effect.

Piano sound samples are taken for an inadequate number of intensity levels, hence, digital pianos typically are unfortunate to have the   continuous tumbrel changes, which characterizes real acoustic pianos.

Earlier digital pianos, such as those produced in the 1990s, often had its polyphony limited to only 32 or 64 notes, and its sampling system were comparable to standard home keyboards.

However, advancement of technology is a continuous process, and, today, it is moving forward too fast. With the technological advances, recent digital pianos are designed to recreate string resonances, reverberations and other acoustical effects via digital signal processing (DSP) and modeling technology.

Modern pianos are able to generate such acoustical effects by means of a simple DSP, which is far less complex than physical modeling.
