What our customer's say!

"Yes, Virginia, the AC Adapter is Included!", I am not a professional musician, but I have dabbled in music most of my life without ever settling on a specific instrument (I did blow a mean blues harp in the eighties). I was recently inspired to pick up an inexpensive keyboard after watching a PBS special demonstrating just how easy it is play the piano...as long as you're not expecting to become a classically trained concerto master, anyway. Heck, if I can handle a typewriter keyboard, then I might have enough dexterity to fumble out a song or two during the holidays, eh?

I studied all the choices, price ranges, features and options here on amazon.com before settling on the Yamaha YPT-400AD. I would have preferred to purchase the YPT-400MS since it also comes with a keyboard stand, but it was only a few bucks extra to buy a stand separately, and I was in too much of a hurry to wait two months for it to be delivered.

Yamaha YPT400MS Portable Electronic Keyboard with 61 Full Size Touch Sensitive Keys and Keyboard Stand

In case you wondered, YES, THE YPT-400AD COMES WITH THE AC ADAPTER INCLUDED IN THE BOX. An important consideration for me, since I prefer not to leave a steaming trail of used batteries behind me when I leave the planet.

Simple to use, but extremely powerful with all the included features that Yamaha so thoughtfully included in this keyboard. I had a spare USB (a-b) cable sitting around the house, and I was able to get connected to my PC running Windows Vista Ultimate in seconds. The included software is easy enough for even my own parents to install.

The most difficult part of my experience with this keyboard is knowing when to stop. I've had it in the house for almost a week, and I haven't spent a spare minute doing anything but playing around with it. The comprehensive documentation sits open nicely on the (also included) music stand so I can read while I explore the seemingly limitless options and create soundtracks for my home videos, and fiddle with the simple controls to make it sound like I'm making it sound that good on purpose...even though I'm really just hacking around right now.

Hope you like yours as much as I like mine!


"Great Keyboard for the price", This keyboard is packed with features and easy to use. The portability and midi features are a plus. I would recommend this for anyone who wants to connect to a computer for sequencing or notation software.

Great product.

"Yamaha YPT400AD", I'm very pleased with the Keyboard. I find that the keys have the same feel as a regular piano. I'm still learning to play and read music, but I have not used the learing program. At 75 I find the little screen a little to small for me to see the knotes. They are blue on a blue screen and black would have more contrast. Over all it's great. I also bought the foot pedal.
