Dazzie: I sent you a PM about the audio hookup. As for your computer ... I do quite well with a laptop that's an old dog compared to yours. I don't think you'll have any problems.

To connect the piano, just use a USB cable, the same kind commonly used to connect a printer to a computer. Install the Yamaha USB/MIDI driver and you're good.

Yes, you CAN feed the computer-generated sounds back to the piano. But I wouldn't recommend it. Piano internal speakers are crappy. You really should use external speakers.

If you rely on your laptop's sound card, you'll have only the headphone jack for sound output. Not the best. It would be better to get an external sound card/box. Such a box can be connected to any sort of amplifier/speaker system.

Connect it using a USB cable connected to the "USB-TO-HOST" port.

You would plug your speakers into the usual line-out port of your laptop. On some laptops this port switches from headphone to line-out. The latter is preferred.

EDIT: macmacmac beat me. Just do what he said.

could anyone recommend a good external sound card/box to use with my laptop?

I use the Presonus AudioBox USB. I bought it used for $76.

For slightly more you can get the M-Audio Fast Track Pro USB.

Either one can plug into a computer USB port. They're very easy to use.

There's also the focusrite 2i2. The XP drivers don't seem that good (at least they don't work well for me...I use ASIO4ALL instead) but I understand that the Windows 7 drivers are good. The hardware is excellent.

On the (significantly) cheaper end, there's also the Behringer UCA 202. Saves a lot of money, excellent drivers...very solid and trouble free. It just lacks volume knob and balanced inputs/outputs.

I've had both these and they both work well. The Behringer was less trouble and only $30 new.

Thanks for the help I just want to make sure i am getting the right one is this the right external card .
