Like your Yamaha midi needs drivers.

Windows 7 Verifying Yamaha USB MIDI Driver Installation and Connectivity https://www.yamahamusicsoft.com/help

should work...but you might have to write your own driver for it. Seems to have drivers for Windows or Mac only.

Casio has this driver on their support page: https://support.casio.com/en/support/download.php?cid=008&pid=20 . Scroll down to the drivers section and click on the link for Digital Keyboards/Piano (excluding PL-40R) for 32-bit OS versions. This link is to the left. Currently the link for the 32-bit versions of Vista, Win7 and Windows 8 is https://support.casio.com/en/support/download.php?cid=008&pid=75 .

I hope this helps.

I couldn't find any drivers available for Windows 7. However, you may be able to run it in 'Compatibility Mode'

See: How to run in compatibility mode Windows 7

If this information was helpful, please give me a big thumbs-up when you rate my answer. Thanks!

You need a 64 bit driver for your sound card so that you can install it in windows vista 64 bit operating platform. Visit the product website and obtain the 64 bit version of its driver for windows vista.

On reading specs, use of the USB is NOT supported on a MAC or on other than the 32 bit version of Vista. If you happen to have the 64 bit Vista, it won't work. All the other versions of Windows seem to be supported..

SOMETIMES one must install the software BEFORE connecting the USB cable to the unit. SOMETIMES one must install the drivers in SAFE MODE. These things are ridiculous, but some of the quirks of Windows are stupid.

I was successful installing a Casio Privia PX-575R USB midi keyboard to Windows 7 Ultimate x64!!!
I tried to use Yamaha, Korg, M-Audio, and some other drivers I don't remember and
they did not work.

I then downloaded the win 7 x64 driver for PC-50 from
http://www.roland.com/products/en/_support/dld.cfm?PRODUCT=PC-50&iRcId=16224976&dsp=1
(but I bet any of them would work) from Roland. All I did was change the hardware ID
in the INF file under

[Roland.NTamd64.6.1]
;; Windows7
%RDID0053DeviceDesc%=RDID0053Install, USB\VID_07CF&PID_6802

The ID is after the comma and the one you see above is from the Casio keyboard i have. The
hardware ID for your keyboard can be found in "device manager". Just choose your
hardware/keyboard and go to "details" and choose "hardware id" from the drop down
menu and put that after the comma. It will start with "USB" since it is a usb
devise. There may be more than one ID but the first one works for me. Then just do
a manual install by right clicking "computer" or "my computer" and click "device
manager" tab. Then find your keyboard (probably a yellow exclamation mark next to
it) and double click it. Then go to the "driver" tab and click "update driver".
Then choose "Browse my Computer for driver software", then "Let me pick from a list
of device drivers on my computer", then "Have Disk..." and browse for the INF file
you just put the hardware ID in and click "open".

You now have a working Casio keyboard for a 64 bit or x64 windows 7 operating system.
You can do the same with Vista x64 or XP x64, just download those drivers and edit the hardware ID the same way.

Thanks

i have no sound drive in my system so please permit me 2 download sound drive from ur product please grant me 2 download

I got one of the drum kits last Christmas, but I have a Mac. Finally, this Christmas, I got around to writing a driver for it. I mean, why not? It runs in Terminal and translates the drumkit hits to MIDI messages which you can use to control GarageBand or Logic or send out a MIDI interface to control MIDI hardware. Doesn't have any of the fancy learning modes or anything, though; just lets you play it. Email mail_ben_schmidt at yahoo com au if you're interested. I doubt it would take much modification to get it to work with the piano, which I expect works on exactly the same principles. But I don't have a piano, so I would need to collaborate with someone or have one lent or donated to me to do that.
