Why a Digital Piano?
Are digital pianos as good as “real” pianos?

Most people cannot tell the difference between traditional pianos and digital pianos today. This is because modern technology is so advanced that digital pianos can replicate the touch and feel of ‘real’ pianos so accurately.

Do the keys feel real?

Yes. The keys on digital pianos are usually ‘weighted’ so the way they feel to play and react to your input is just like the real thing. Don’t think that digital pianos feel and sound like that old Casio keyboard you got for Christmas in 1986.

Do they need tuning?

No. Digital pianos never go out of tune, so never need tuning.

Do they have the right amount of keys?

Yes. Most digital pianos have the standard 88 keys.

Can I wear headphones to practice?

Yes. When you plug headphones into a digital piano the speakers are disabled so only you can hear the sound. This is ideal for practicing late at night or when you don’t want to disturb anyone. Note: The standard jack socket for headphones is 6.35mm. iPhone headphone plugs are 3.5mm so you would need an adaptor.

Why do digital piano prices vary so much?

The price of a digital piano depends on a number of factors, for example whether the keys are plastic or wooden, whether the speakers are big or small, the amount of extra features it has like rhythms and backings or multi track recordings. The cabinet design and finish is a factor too. Small portable pianos tend to be cheaper than the more traditional looking non-portable ones.

Can I connect my iPhone/iPad?

Many of the Yamaha digital pianos and keyboards allow connection to an iPad/tablet now for various purposes. Yamaha have developed a lot of apps for their instruments, you can read more about them on the App Store.

What about other manufacturers of digital piano?

We are an independent shop but choose Yamaha digital pianos exclusively because they are regarded as the best in the world. You will find Yamaha digital pianos in most music schools, colleges and universities, and teachers nearly always recommend Yamaha because of how authentic the touch and sound is.

DGX-640 is Yamaha’s most piano like ever, with weighted graded hammer actions, ultra-real feel and more. All the best sounds are available at the push of button and recording virtuoso performances is simple with built-in recorder. The Yamaha Education Suite and USB connectivity add functionality.

  • 88-key Graded Hammer Standard (GHS) keyboard with matte black keytops
  • Acoustic, super-expressive Live!, Cool! and Sweet! Voices and DSP included
  • Easy Song Arranger feature and Performance Assistant Technology
  • USB connection for convenient storage and song data playback
  • Optional three pedals unit for expressive effects

Graded Hammer Standard (GHS) Keyboard with matte black keytops

Just as on a traditional acoustic piano, the keys of the lower notes have a heavier touch, while the higher ones are more responsive to lighter playing. The keyboard’s sensitivity can even be adjusted to match your playing style. This Graded Hammer technology also enables the instrument to provide authentic touch in a lightweight instrument.

Amazingly Realistic Sounds

Yamaha’s highly acclaimed Sweet! and Cool! Voices deliver incredibly natural and dynamic sound. Use the Pitch Bend wheel, and hear these Voices–especially the Sax and Trumpet–truly come alive!

Live!, Cool! and Sweet! Voices

A huge palette of acoustic and electronically amplified instrument sounds. A blend of long, stereo and multi-layered samples is used to fully capture the natural presence, resonance, expression and vibrato of the real instrument.

Digital Signal Processor (DSP)

The DSP effect can be added to the Main and Dual Voices. These range from reverb-like ambience effects to distortion and other dynamic processing tools that le you enhance the sound, or completely transform it.

Easy Song Arranger

In addition to each song’s default style, you can select any other style to play the song with the Easy Song Arranger feature. This means that you can play a song that is normally a ballad, for example, as a bossa nova, as a hip-hop tune, etc. You can create totally different arrangements by changing the style with which a song is played. You can also change the song’s melody voice and the keyboard voice for a complete change of image.

Performance Assistant Technology (P.A.T.)

Play along with a song on the instrument’s keyboard and produce a perfect performance every time … even if you play wrong notes! All you have to do is play on the keyboard–alternately on the left- and right-hand ranges of the keyboard, for example–and you’ll sound like a pro as long as you play in time with the music.

Music Database plus External Files

You want to play music in your favorite style, but you’re not sure how to select the best voice and style for the type of music you want to play … simply select the appropriate style from the Music Database. The panel settings will automatically be adjusted for the ideal combination of sounds and style! Furthermore, this instrument allows Music Database files transferred via the internet (http://services.music.yamaha.com/). These files can be used in the same way as the internal Music Database.

USB TO DEVICE Terminal

Insert a USB flash memory in the USB TO DEVICE terminal on the instrument. It would let you save or load the registered settings and user songs created on the instrument, as well as read data from the connected device.

USB TO HOST Terminal

Dive in and take advantage of the wide world of computer music software. Connections and setup are exceptionally easy, and you can play back your computer recorded parts with different instrument sounds – all from a single instrument.

Portable Grand Button

Playing piano is fast and easy with Yamaha’s Portable Grand function. One dedicated button brings up a great sounding piano, stunningly rich and authentic in its sound as well as setting up the keyboard to play as a piano.

Easy Performance with Music Notation Display

When you play back a song, the corresponding score will be shown on the display as the song plays. This is a great way to learn how to read music. If the song contains lyric and chord data*, the lyrics and chords will also appear on the score display. * No lyrics or chords will appear on the display if the song does not contain the appropriate lyric and chord data.

Yamaha Education Suite (Y.E.S.)

Yamaha Education Suite (Y.E.S.) is an advanced set of helpful learning tools built into the instrument, letting you teach yourself how to play and perform. Y.E.S. helps you master a song with easy lesson steps. Each lesson can be done in isolation with either your left hand or right hand, or both.
