To play music with media system you should have IBM-PC media interface card, digital piano with media socket, program that supports the media, and media cable.

Upright pianos used at home tend to have 2 pedals but there is no problem of playing for digital piano with one pedal on left and the other on right.

For upright piano the right pedal is referred to as ‘damper pedal’ which makes sound even if one is not actually playing the keyboard.

Left pedal is called ‘soft pedal’ which reduces volume of the sound while playing.

The middle pedal is called ‘special pedal’ or ‘extra pedal’ and this weakens sound to prevent any noise.

For digital piano it has a function of controlling volume and if one uses headphone, noise can be prevented. Thus, this is why there are digital pianos with only 2 pedals, without the middle one.

For grand piano used for playing, the role of left and right pedals are similar to upright piano, however, middle pedal is called sostenuto pedal. The function of this pedal is different from upright piano in terms that it only maintains the sound of key that was pressed before using the pedal.

Even for digital piano, function of left and right pedals are the same but depending on the product, the middle pedal may have sostenuto function of grand piano or special pedal of upright piano which is to start or stop the rhythm.

They are different in terms of appearance but are the same in the perspective that they both make sound based on electrical circuits.

The advantage of electrical keyboard is entertainment and convenient sides and for digital piano, its main goal is to replace actual piano with the same concept of it.

* Keyboard: Most electronic keyboard has 61 keyboards and digital piano has the same 88 keyboards with regular piano.

* Function: In general, most electrical keyboard has multi-functions but digital piano ranges from simple piano function to multi-functions. Thus, customers can have a bigger option.

Before, people preferred electronic keyboard because it is cheap. However, with advance of technologies, the price of digital piano is becoming more and more reasonable.

Due to this reason, there are lot more customers purchasing digital piano than electronic keyboard.

The most important component of digital piano is keyboard.

Weighted Keyboard gives weight onto the keyboard when is pressed based on tensile force of spring and hammer. This has an advantage of cheap price but its touch is not as good as hammer type.

Hammer action keyboard gives weight to the keyboard based on dynamic structure of hammer connected to the keyboard. It provides similar touch feeling with regular piano.

(has the same keyboard standard with acoustic piano)

CRAWZER is the only company that has its own manufacturing facility to make the high quality hammer action keyboard. It is strongly recommended for traditional education with its optimal touch.
