Usb device not recgonized

CTK 481 only has MIDI-IN and MIDI-OUT ports & no USB. So you need to buy a USB-MIDI interface (cable-like) preferably one that is class-compliant for you OS. Class-compliant device do not need drivers (PCs, MACs, IPAD).

What is the model of your sound card?

If your computer has a SD card reader, you can use a 2GB or smaller SD card. Format the SD card using the CTK4000. Drop tje music into "MUSICDAT" folder.
If you connect to PC using a USB cable, you need to download DATA MANAGER from Casio website. DATA MANAGER allows you to copy files from computer to keyboard.

Make sure the driver is compatible with your operating system... often stuff will not work with Vista for example. Often SOME software REQUIRES it to be installed before USB cable is connected, and yet other requires it not be connected till software is installed... read the manual...

If it is installled as plug and play you should see it in your devices in the XP system manager and also in the bottom right task bar where other usb devices show. If it shows there, it is installed and you just need a sequancing software to use it

You MAY need to connect a MIDI device to it to get it to light, not just plugging into the computer. The MIDI communication current comes FROM the device being driven an ONLY flows when a device is CONNECTED.

Hello,

You need a midi to usb interface, otherwise it is quite simple. I personally have an M-Audio interface that plugs into my midi out and plugs into your usb port on your computer. Once done, you can create a profile in Reason for your CTK. Windows 7 will notice the M-Audio device and then you will be able to use midi. You may have to install a specific driver for the particular M-AUdio device (or another midi to usb interface) but that is simple. You do not have to worry about a driver for the keyboard.

In my experience, M-Audio makes about the best midi/usb interface, and they come in all popular configurations. I use a very small 1-to-1 interface, though there are multi port interfaces one can buy. I purchased mine on eBay, though you can find them at Guitar Center if you have one in your City, or alternately Musiciansfriend.com web site. Many online stores sell them though. You amy want to use Amazon or a price comparison web site to find your best deal.

Thank you for using FixYa, and good luck.

Replace the batteries and get an AC adapter for it! These do NOT work when voltage os too low.

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.

Try uninstalling and reinstalling both the keyboard and the game. If that doesn't work then the keyboard may not be compatible with the software.
