Description Amazon is clear that the AC adapter is "the box". But mine does not have one, and product information, both Casio and the carton itself says no adapter is included. This is really bummed me out, I asked for this for Christmas thinking it would be able to shoot immediately, but no luck. Yes, you can power the batteries, but now I have to order the power to really enjoy it. This advertising is false, and I'm pretty tired of it. In fact, while we're at it, because it comes with the adapter? Pretty cheesy treat everything.

I got as a Christmas present and I played on it since then. Piano sounds very real, and the pressure sensitivity is a cool feature. It is also with programs that can teach how to play. It comes with 100 different styles of songs (classical, country, pop). I bought the midi cables, accessories, so I can connect with my computer and it works fine. Take care.

Yamaha YPT-400 has USB MIDI

I bought the Yamaha YPT-400 and through a regular USB cable I was able to:
(a), add / drag songs (file.avi MID) from one computer to WinXP.
(b) use the USB-MIDI … Play Pooh-400 as a MIDI keyboard and play / record on computer using a third-party software 3 MIDI (I used Voyetra Teach Me Piano Deluxe).
- Keyboard USB MIDI is seen as "Yamaha Porta Tone-1" to "General MIDI" of such a MIDI software on your computer.
