The evolution of the piano as an instrument has seen a whole lot of developments and improvements. It had delighted homes, halls, and concert venues across the globe since its creation in the 18th century.

Pianos can be divided into four different categories. We have the vertical piano, horizontal piano, digital piano, and keyboards. Recently, digital pianos have become the most sought of all. This is because they have a number of desirable features. For instance, it is capable of producing a wide range of sounds, including the precision similar to traditional pianos. They can be incorporated in musical productions too. But most importantly, they are relatively affordable.

It comes with a touch-responsive keyboard with 88 fully weighted keys. It features the Graded Hammer Standard (GHS) keyboard action, which is similar to that of the Yamaha P-45 and P-115 digital pianos. The GHS reproduces the feel of an acoustic piano with a heavier touch. Yamaha DGX-660 is also touch-sensitive. This means the harder you press the keys, the louder the sound it will produce. The keyboard has four preset settings – soft, medium, hard, and fixed.




Yamaha DGX-660 features a Pure CF sound engine, which can also be found in the Yamaha P-115, the P-255, and pianos from the Arius line. It has an impressive library of 10 other piano sounds, hundreds of other instrument sounds, and a wide range of sound effects. This instrument also comes with a Pitch Bend wheel, a master equalizer, and a Digital Signal Processing mechanism.

There are three modes offered by the DGX-660: split, layering, and duet. The Split Mode divides the keyboard into two parts. It allows the player to play two different instruments per hand. For example, the right-hand plays the piano, while the left for the drums.

The Layering Mode allows you to play two different sounds simultaneously. For example, one key can play both the organ and the piano. Lastly, the Duet Mode is suitable for beginners. The keyboard here is split into two similar halves. Each half can be used as an entirely separate keyboard.

Recording and Playback

Yamaha DGX-660 is compatible with both MIDI (SMF) and audio (WAV) format data. The MIDI format records the sequence of notes including their length and velocity. Apps like Windows Media Player, QuickTime, and Winamp can interpret MIDI data on your computer.

In the Waiting, the song will wait until you play the right notes as shown on the LCD screen. The virtual keyboard will show both the notes and the keys. The Your Temp lesson lets you try to play with the correct timing. You will notice the melody to slow down when you hit the wrong notes. Lastly, the Minus One lesson allows you to play a part of a song you want to practice (left or right hand. You will play it along with the playback of the other hand-part.
