And to make sure you never run out of notes, the YPG-635 features 64 notes of polyphony.

Yamaha's 88-key weighted graded hammer action YPG-635 keyboard.

Lyric, Chord And Notation Display

The YPG-635 can display the score to a song whether it comes from the Internet, the internal selections or ones that you record yourself, and the pages scroll automatically when a song is played back--no more page turning. And for singers, the screen also displays chords and lyrics to XF compatible songs. And for those that want to learn to play, notation adds a new dimension to the Yamaha Education Suite, allowing you to hear a song while you follow the notes in the display.

USB Connectivity Brings Music Directly To Your Keyboard

The YPG-635 has 2 USB ports on the back with the following functionality
  • USB TO HOST is plug and play simple for recording and playing back MIDI files, as well as transferring data to and from your computer.
  • USB TO DEVICE is for connecting optional peripheral USB storage devices like floppy disk drives and thumb drives. When a USB flash memory is inserted in this instrument's USB TO DEVICE terminal, user songs created on the instrument and the registered settings can be saved to or loaded from the memory medium. USB flash memory can also be used to transfer song data downloaded from the Internet to the instrument, where it can be used with the performance assistant technology and the Yamaha Education Suite features mentioned below. Furthermore, user songs saved to USB flash memory in MIDI file format can also be used with these features.

Ease of Operation

There are many tools in the keyboard that make it easy to be a power user from the first day you own the keyboard.
  • Expandable Music Database: Complete keyboard setups by song title. The keyboard selects an appropriate voice for the right hand melody, the correct musical style and the correct tempo. Simply call up a song title and start playing.
  • One Touch Setting (OTS): Provides you with a recommended voice with effects for each Style. For example, on a jazz style OTS might be piano, for a Latin style it might be acoustic guitar and for a rock style it might be a guitar with overdrive etc.
  • Registration Memory: Set the keyboard up just the way you like and take a digital snapshot by memorizing it to one of the Registration buttons. Load and save up to 16 Registrations to User memory. The Registration buttons are conveniently located just above the keyboard.
  • Performance Assistant Technology: Performance assistant technology is a feature from Yamaha that guarantees that you can't play a wrong melody note or chord. Here's how it works. Select a song, press the Performance.

The USB ports on the rear of the keyboard allow you to play back MIDI files, record songs played on the keyboard, and transfer files from your computer.

Yamaha Education Suite

The YPG-635 has 30 built-in songs plus 70 more on included CD-ROM for you to learn to play using the Yamaha Education Suite. The songs are separated into left and right hand parts, providing 7 levels of lessons plus a convenient chord dictionary.
  • Three keyboard lessons for each hand
    • Waiting Mode: stops the playback of a song until you find the correct note and then continues.
    • Your Tempo Mode: Learn to play the correct notes with the correct timing. Song playback tempo will vary to match the speed you are playing at. The song will slow down when you play wrong notes, so you can learn at your own pace.
    • Minus One Mode: Here's where you can perfect your technique. The song will play at the normal tempo, minus the part you have chosen to play. Play along while listening to the song.
  • Lesson Grading – monitors your progress as you practice each lesson and gives you a grade.
  • Repeat and Learn – The song location will move back four measures from the point at which you pressed the button, and playback will begin after a one measure count-in. This section will repeat allowing you to practice until perfect!
  • Chord Dictionary – shows you how to play chords and tells you which chords you are playing by displaying the notes and chord names on the LCD screen.

6-Track Sequencer: Record Your Own Music

Imagine capturing your child's first performance or writing and recording your own songs. With the YPG-635, you have the equivalent of a built-in multi-track recorder to record one or multiple instrument parts at a time and assign each part to a different track. Six tracks are provided to accommodate sophisticated melodies, chord accompaniment and rhythm parts.

It comes with an attractive matching stand.

Sound Quality

  • 2-Way Speaker System: Separate woofers and tweeters deliver sounds with clarity and precision for more lifelike instrument voices.
  • Bass Boost System: A special port on each speaker adds a powerful impact to bass sound reproduction.
  • Stereo (Not just 2 Speakers): We all know that stereo sound adds realistic character and spatial depth. But how can you tell if the portable keyboard you're looking to purchase is stereo or not? With Yamaha, the answer is simple. All Yamaha Portable Keyboards are true stereo.
  • Digital Signal Processing (DSP): Enhances sound quality with sophisticated digital effects like Harmony, Reverb & Chorus.
  • Advanced Wave Memory (AWM): Yamaha Advanced Wave Memory technology delivers amazingly realistic sound.

Digital Effects

Yamaha has long been a world leader in digital signal processing technology. In fact, Yamaha professional audio products are found in most professional recording studios around the world. The YPG-635 takes full advantage of this know-how, giving you an extensive range of twenty-nine, top-quality reverb effects that simulate playing in everything from a small room to a large spacious concert hall and twenty-four chorus effects that add richness to electric pianos and guitars in particular and 182 DSP types for adding everything from distorted guitars to rotary speaker effects. You'll also find 26 types of Harmony effects for your melody part.

Full Keyboard Mode

The YPG-635 delivers on its piano theme with a special mode of fingering called Full Keyboard Mode. This allows the player to play the keyboard like a piano; for example a chord with the right hand and bass notes with the left. When using the accompaniment feature, the virtual band will follow these chords. Traditional portable keyboards normally require you to chord on the left side of the keyboard, in the bass section, which is foreign to most piano players. The YPG-635 is also capable of this mode, for those who prefer it.

Digital Music Notebook

Digital Music Notebook is a multimedia Internet service that enables you to preview, purchase, download and print learn-to-play music books and chart-topping sheet music. From scales to chords to your favorite riffs, Digital Music Notebook is jam-packed with all the secrets you need to master your instrument. Add accompaniments, record and mix yourself, sing karaoke with friends, learn new techniques while having a blast--Digital Music Notebook delivers everything you need to bring music alive! And it's included with the YPG-635.

Realistic Sounding Voices

The YPG-635 comes equipped with 130 panel voices, 12 drum/SFX kits plus 361 XGlite voices. Special voices include Sweet! Clarinet, Trumpet, Muted Trumpet, Flute, Pan Flute, Soprano & Tenor Saxes, Trombone, Cool! Voices including Galaxy Electric Piano, Suitcase Electric Piano, Electric Piano, Organ and Rotor Organ and Live! Voices including Grand Piano, Warm Grand Piano and Orchestra.
  • Sweet! Voices reproduce all the natural expression and vibrato of their respective acoustic instruments
  • Cool! Voices feature long samples of electronically amplified instruments
  • Live! Voices use stereo samples to ensure the most accurate reproduction of each instrument's natural presence, resonance and vibrato
  • Dual Mode allows you to combine two voices across the keyboard at the same time--for example piano and strings.
  • Split Mode allows you to select a different voice for each hand--for example piano for your right and bass for your left. The combinations are limited only by your imagination.

64 Note Polyphony and 16 Part Multi Timbrel

In electronic keyboards, the more sounds made at the same time--polyphony--the more memory is needed. Obviously, more is always better, because too little polyphony can cause dropouts in dense passages of music. The YPG-635 has 64 notes of polyphony and will play back 16 different parts or sounds at once (16-part multi timbrel); enough for the most demanding needs.


Just what the teacher ordered! A fully adjustable metronome is just a button push away.

By N. J. Simicich VINE VOICE on December 5, 2008
If you've ever moved a real piano, you know the problem. Moving a piano needs to be done by a professional. Pianos need tuning.

But, at the same time, nothing is quite like a real piano. The feel of playing one, the sound - hundreds of years of development have combined to bring the sound and feel to its current state and, when it all comes together, there is nothing quite like it.

But that comes at a price. Did I mention tuning? Action tuneups?

So was developed the keyboard - and the keyboard feels like a keyboard - the action is wrong. And it does not have the rich sound of a piano.

So we arrived at the electric piano. Early electric pianos were neither fish nor foul - they were partially mechanical devices that still needed to be mechanically tuned. The actions were more or less horrible. The sound was that of an electric piano, not a real piano.

The Yamaha sounds like a piano - within the limitations of its speakers. Its action? Better than some real pianos and much less likely to need an action tuneup.

And all the benefits that you can get from modern electronics. Full DSP so that you can get simulated concert hall acoustics if you want.

This is an amazing item. It comes with 30 songs programmed into it, and 70 more on an included CD - and if you are inclined to learn them, it can teach them to you. More music can be downloaded using the software provided and your computer can load them into the piano or you can use a thumb drive to move them. You can learn the left and right hand parts separately. It will show you the music, and the corresponding piano keys that you need to press on the little display. You can start slow - and it will wait, patiently, until you find and press the correct key.

The other reviews cover the good points: the keyboard, the sounds, and the features. So, I'd like to cover one relatively small disappointment: the maximum volume. The built-in speakers seem decent enough, but the keyboard needs to be played at maximum volume in order to be heard.

We bought this keyboard so that a parent could play along with our kid during practice. We have an upright piano with above-average projection (i.e., loudness). The YPG-635 isn't as loud as our acoustic upright even at maximum volume, so we find ourselves playing with the volume set to max most of the time.

Most people probably won't find this a limitation, but if you want to perform for a small group with this keyboard, you may want external amplification.

BTW, this keyboard appears to be identical to the DGX-630, so buy whichever is less expensive.

The Yamaha YPG-635 is an excellent value. There are a few things I think Yamaha could have done better, and thus the four star rating. In summary: Good sound, great keyboard, great value.

The Good:

This keyboard has excellent and realistic keyboard action. I played on several at a music store to see which of the various brands felt best. To my fingers at least, none of the keyboards in the price range felt any better (and even many that cost more didn't feel as real). It's easily within the normal variation of real piano keyboards. This was the key deciding factor for picking this keyboard.

The Grand Piano voice is good, easily acceptable. There are better sounding piano voices; typically found only in instruments at twice the price.

The general MIDI spread of voices is decent, and many are top quality. The extended voices are very good as well, but are obviously synthetic. Two of the deciding factors for me were the 64 note polyphony and the general MIDI compatibility. I play a lot of MIDI files and my old keyboard was not general MIDI compatible (it had the voices on the wrong patches). Many songs overrun the 28 note polyphony of my old synth; they do not on the YPG. I'm sure I could create sequences that need more that 64 note polyphony, but for the most part, 64 is enough (128 would be great, though).

For a complex keyboard, most of the functions are easy to use. For the complex things, there is a menu selection system and scroll wheel that I've found works fairly well. When I'm actually playing the keyboard and not running MIDI files through it, I prefer to use the "Grand Piano" button and have it simply be a piano. Easy.

The Value is amazing. There are cheaper keyboards with as many voices.

I have been wanting to upgrade my keyboard for a while, and I finally decided that I was ready for the investment. I wanted to do it right. I live in an apartment, so I wanted to play a "real" piano in a more manageable way. I only did a few hours of research, and it seemed to be clear that Yamaha manufactures solid digital pianos and are the industry leader. The YPG-635 seemed to be right in my budget and had everything I wanted. I bought the item with one-day shipping because I couldn't wait. The keyboard rocks. I love the design/look and the feel of the weighted keys. The assembly was painless. The sound is simply amazing. Although the maximum volume is not as loud as I would imagine, the internal amp and speakers always supply a clean, crisp sound. The voices are great. The Live! Grand Piano effect sounds just the grand piano I played as a kid at the ole 'rents house. I highly recommend this digital piano for all novice piano players. I am almost certain that this is the best digital you can buy under $1000.
