Yamaha P70 is one of the best pianos for both piano students who just start learning to play and accomplished pianists who want a piano that is light weight and portable. This type of a piano is designed in two variations: P70 which is black and P70S which is silver. It has a keyboard with the graded hammer effect to help a pianist to feel that he has got a good responsive keyboard and also motivate him to play more.

Yamaha P70 has an Advanced Wave Memory and sampled sounds that feature a grand piano with 30 sample points which are different, so that an accurate digital emulation of the nuances of a genuine piano can be enhanced.

It has a built-in speaker system that is designed to reproduce all the quality tones of the P70’s voices that include the built-in digital reverb. The piano also has the MIDI in/out port that increases expandability. For example it enables a user to add melodies of his (or her) choice just by connecting Yamaha P70 to a computer. Among other characteristics of P70 are the availability of 32 notes of polyphony, 10 voices including the grand piano and the dual voice mode for combining two sounds.

A full digital piano system is made up of a keyboard that implements a weighted key action feature, optical or any other electronic sensor that detects velocity with which you strike the keys, a digitized sound bank, an amplifier and speakers. The sound of each note is usually sampled off a high quality acoustic piano.

When the sensor detects the key velocity when a key is pressed, a microchip produces the note with an alternative loudness thus the faster or the harder you hit keys the louder they sound. This functionality is the same with virtually every digital piano. Digital piano keys are normally weighted to approximate the feel of the piano’s keyboard that can even replicate the feel of an organ which may be soft or of very little resistance.

Many digital pianos provide various piano sounds other than standard piano sound, including sounds of a pipe organ and a harpsichord. They implement miscellaneous digital technology that is why the sound is stored in electronic form. You can listen to your digital piano not only through speakers, but through headphones as well, so that nobody except you could listen to what you play. A digital piano is relatively portable and does not need tuning.
