88-key portable keyboard

The Yamaha YPG635 88-Key Weighted Portable Grand has a pretty responsive keyboard and the action mimics a grand fairly well by means of a scaled weighted keys. The keys are actually heavier scaled to lighter depending on position, heavier in low end and lighter in the high end.

What we like about weighted keys is a person learning becomes accustom to the sound and feel of what a piano should feel like, something that’s been neglected in digital for some time. The fact that the weight of the keys is more true from lower to high ends is icing on the cake.

Included Songs Suite

30 songs are pre-loaded and an additional 70 are included with the cd-rom disc. This means you have something to work with right out of the box as any investor would tell you it should be.

USB Ports

Need more connectivity? More Storage? The Yamaha YPG635 includes 2 USB ports built-in. USB TO HOST and USB TO DEVICE.

The USB to Host means you can record or play back MIDI files or transfer files to your computer.

The USB to Device is similar allowing more complex usage.

A good way to think of the difference is by looking at a computer USB plugin port on your computer, and comparing it to the main USB plugin for the printer. One is more a parent and the other a child USB port.

Stereo Sound

Two-way stereo speaker system makes since because we humans hear in stereo anyways. Two way mean two separate tweeters and woofers which makes the instruments sound more live.

The sound system includes bass boost, and digital signal processing for enhanced sound. Lets face it, we’ve all heard sound systems without good bass, and if you want that, buy a 100 dollar keyboard because they all have it…junk.

LCD Display

The LCD Display makes for a nice information center as well as learning center, providing you have good eye sight as its a wee bit small. The Yamaha Education Suite is included and will help you to master piano learning via the easy to read display.

Pros and Cons


Price. For what your getting the price is great.

The weighted keys with grand piano action is a great feature for getting the feel of playing.

USB ports, one is great, but two is fantastic.

The Recorder feature. A great way to learn is to listen to yourself, especially with a trained ear guiding you when you’re not preoccupied with trying to do. This is also great to record your or your childs progress from the first time you play to recitals.

The Triple pedal is also a great feature, it delivers everything you need from full sustain, soft and left hand sustain.


Poor amplification. This part must have been designed by apartment tenant control committees who wanted to make sure you would never be too loud. Compared to the Casio AP420 Celviano there is a huge difference. And no line out jacks to be able to use outside amplification without interference.

Head Phone Jack plugs in the back. What were they thinking, drap the cord across the keys?

While we appreciate two USB ports, why are they on the back. Stuff like that belongs on a front hidden panel like all computers adapted to for hooking up more easily. Heck even TV’s put line in and line out jacks in the front. Yamaha…you know better.

Final Thoughts

The main ingredients to be pretty happy with a Piano are the feel and sound for most people. From that prospective the Yamaha YPG635 feels better than most you’ll come across even at higher prices, Yamaha did a great job with the realistic action.

The Sound is also very good, the voices are accurate and an asset, it only lacks in the ability to produce reasonable volume. But with the headphones on its a non-issue.

We wish they would have done better with the jacks, and ports and put them in the front but as we said the main ingredients are the feel and sound. So based on that the Yamaha YPG635 88-Key Weighted Portable Grand receives a strong buy recommendation.
