The Yamaha YPG-635 is an 88-key portable grand piano keyboard with weighted, graded hammer- action and a sturdy, stylish built-in stand. Upgrades from the previous model include 64-note polyphony, an optional 3-pedal unit, along with additional DSP (Digital Signal Processing) effects that enable realistic-sounding Distortion Guitar and Rotary Organ. The Yamaha YPG-635 includes USB MIDI and USB-to-Device for removable storage, along with a high-resolution "Live" grand piano sample, large Wave ROM for higher-level samples, a song recorder, and a large backlit LCD (320 x 240 dots) display that shows notation, lyrics, and chords.

The YPG-635 keyboard is an affordable, feature-packed portable piano and features an authentic grand piano-like touch: heavy in the low end, feathery light in the highs, and amazingly responsive throughout.

Clavinova-like features in an inexpensive package.

By Jesse Elizondo

from Madison, MS

Comments about Yamaha YPG-635 88-Key Weighted Portable Grand Piano:

This keyboard is basically an MM8 with a stand and built in speakers, minus MIDI in/out and dedicated line outs. It contains some of the original digitally-sampled Motif sounds, including the excellent acoustic piano. All of the patches from 140 onwards are PCM however, from the PSR consumer line. The polyphony has been upgraded to 64 on this model, from 32. The keyboard is the same as Yamaha's GH, used in the low-end Clavinovas. The screen and interface is also borrowed from the entry level CVP's. Unlike the Clavinova, it does have a pitch wheel. The speakers are less powerful but are loud and clear. The stand is very stable. USB MIDI song player is a useful function, with sequencing and notation display. Overall, I am amazed by how many high quality features are present in a keyboard in this price range. For gigging or church/live performance, the MM8 would be a better choice due to the poor signal to noise ratio of the headphone out. If you can live without MIDI & line-out, this is an excellent home keyboard for practice and enjoyment.

Comments about Yamaha YPG-635 88-Key Weighted Portable Grand Piano:

Wow, is all I can say after playing this keyboard for about 3 weeks. I bought this from a local music store, and was blown away when i first played it. One thing that i love about it is that it has over 500 sounds on it!! Theres like, a section a pianos, organs, electic keyboards, synth pads, drum kits, and everything you could thik of. You can also record songs on it, and transfer them to your computer via USB. Overall, this is an amazing keyboard, and you won't be dissapointed.

The best of Yamaha.

By AshC

from Naperville, IL

Comments about Yamaha YPG-635 88-Key Weighted Portable Grand Piano:

My dad bought this as a first piano for me and I played it for about 6 months (well, actually it was the YPG-625, but I played this at the nearest shop and I assumed this and that were the same thing) I can't say anything bad about it! This is probably the best piano anyone can get! Great sound, playability, etc. The only seemingly bad thing about this piano is that when you let go of a key, it makes a little "clicking" sound, but that shouldn't hinder you if you don't pay attention to it. Overall, this is a great piano, I recommend it to anyone from novice to experienced. Great price, too!

Good choice

By Ilovepie

from maine

Comments about Yamaha YPG-635 88-Key Weighted Portable Grand Piano:

I had narrowed my choices down to 3 -- this one, a Roland (?) SP50 and a Casio Privia 130. I couldn't find an SP50 to try out. What won me over to the Yamaha was the key action and variety of tones and rhythms. The "sweet" voices are wonderful -- almost wistful. This keyboard has more dsp features and such than I'll ever know how to use. That said, when I got it home and tried out the Split feature, I was stunned that the left hand does not sustain. I bought the 3 pedal unit later thinking that might cure the problem but it didn't. Finally I called Yamaha tech support and was told that only their higher end pianos can sustain in split mode. That's so disappointing and will probably mean I'll sell this and look again at the Casio. I will say that this keyboard looks good, seems sturdy and is relatively easy to use. The speakers are a little weak but headphones sound wonderful. If you decide to take this gigging, you'll definitely want an amp. I would recommend this if you don't care about the split mode. Yamaha did say that a few people complained about that but not enough to make them change their minds.

Great Value, Good Digital Piano

By John B. Sandlin

from San Antonio, TX

Comments about Yamaha YPG-635 88-Key Weighted Portable Grand Piano:

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 GC 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 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 "Portable Grand" button and have it simply be a piano. Easy. The Value is amazing. There are cheaper keyboards with as many voices. There are keyboards with as nice or nicer sounding voices. The combination of price and voices, at least for me, meets in the middle on this instrument. The USB-to-HOST port and associated drivers work with Windows 7 (64 bit). I was worried as my previous MIDI interface doesn't. I have several MIDI capable devices and was planning to replace my no-longer-compatible MIDI interface box (and still may since I still have the other MIDI devices). See my note in the "the Bad" section about the lack of standard MIDI ports. The Neither Good nor Bad: OK, the title for this section is a little humorous (I know, very little). The points I want to make, though, fit in neither the good nor bad, but are comments on advertising hype and expectations. The advertising claims the Piano voice is the best... their words are: "You're never more than a button push away from the most realistic piano sound in portable keyboards today." I have to quibble with two parts. This keyboard, at 70 pounds or so, isn't all that portable (unless you're a professional musician with Roadies to move your stuff), and the sound is good, but not the best since Yamaha's pro-Line portable stage piano's have even better sound (along with much higher price tags). The display isn't big. They advertise playing songs from the score display. You probably won't. It's big enough you could and small enough you won't want to. The wood doesn't seem to be real wood, but more like the particle board with veneer like that of cheap furniture (well, it's a fairly cheap digital piano, so I guess that fits, huh?). However, it is solid (and 70 pounds or so). The auto-accompaniment isn't as feature rich as I expected moving up from my ancient PSR synth. There are more choices, but fewer controls over them. Perhaps I just haven't learned them yet. The Bad: As mentioned a few times in other reviews, the volume isn't impressive. A real piano would easily drown out the YPG audio output. Not an issue if you listen on headphones or are in a small room - just be aware, a large room, like a church or club, will swallow the sound of the keyboard and not even burp. Of course, if you want, you could add amplified speakers or feed it to a PA, but there will be a signal to noise issue since you're using a headphone jack as the keyboard does not have Line-Out jacks. I realize the YPG isn't a pro-line instrument and Line-out is a pro-level feature. Speaking of the headphone jack, it's on the back side of the keyboard, behind the music rest. A really awkward spot if you ask me. On the front would be much better. This is a minor deficiency. While we're on the back of the instrument, the USB-to-Device (for flash drives) is on the back of the keyboard and hard to get to if you have the keyboard near a wall. I bought a 30 inch USB Extension cable so I can plug and unplug my flash drive more easily. Not a show stopper, and not an issue if you don't use a flash drive, but how hard would it have been to put it on the front. The MIDI implementation is Yamaha's USB-to-Host connection. You can't use a MIDI controller to use the sounds of the YPG, or use the YPG to control an external tone module unless you have a computer handy - it doesn't have the standard 5 pin DIN MIDI ports. I thought long and hard about this before deciding I could live without standard MIDI ports. If you need the standard MIDI jacks, think about another keyboard. Conclusion: The YPG-635 is an excellent value, you do get what you pay for and there are a couple of compromises and quirks at this price level. The combinations of features, though, are well worth the price. The sound is good, the keyboard action very good, and the good points far out-weigh the bad points.
