Can anyone tell me if the PSR S900 comes with a power supply? I have one on order but I am not sure if it comes with a power supply. I also see that you can get an optional hard drive... Can't seem to find these or any info on the websites.. thanks

Mine came with the power supply. I don't know about a hard drive. The usb to device is fast enough and large enough storage for me.

Now you can audio record to USB and you can get 4Gb USB drives very cheaply there's little reason if any to go to the expense of getting a HD. Also less to go wrong in the future. As long as you use back up, which should be done in any case.

The unit comes with a power supply. Where did you read that there is an optional hard drive? I concur that this would be unnecessary.

I was reading the writeup on the Musician Friend Website. http://www.musiciansfriend.com/product/Yamaha-PSRS900-Portable-Keyboard?sku=702675

That line on the musiciansfreind description is wrong. Ignore it and forgive them their stupidness.

Thanks... I will ignore it.....
