Can't connect my ctk-720 to my mac

try plugging in without the bateries...Also check your adaptor as well as your ac requirements on your keyboard..It specifically calls for a Casio AD-5 Adaptor.

• 9V power supply; 850mA
• Positive sleeve/negative tip This needs to match your adaptor Good Luck

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).

PC drivers available at Casio

If you have a MAC google casio driver for Macs by 3rd party.

Unplug the USB cable.
Download correct driverfor your OS from

You need to load the driver first and only plug in the USB cable when the software tells you to do so.

what program are you running and did you set up your keyboard with the software so it can recognize it. Depending on what software it is your using as soon as I know I can tell you how to get it working. I use my midi keyboard with everything from reason, Ableton live, pro tools logic logic express vdj traktor basically every software!

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...

Thanks Francois. This is good advice. It is posted in the problems and questions section of musical instrument repairs.

Just did it today. Hooked up CTK-720 to Imac with Snow Leopard (10.2.6) using GarageBand.
Steps: 1) Go to : http://code.google.com/p/casiousbmididriver/ 2) Download the CasioUSBMIDIDriver.plugin (see the two choices on the right side of screen) 3) Place the CasioUSBMIDIDriver.Plugin file into the MIDI Driver subfolder: Macintosh HD => Library => Audio => MIDI Drivers 4) Restart 5) Plug in USB cable, open GarageBand, turn on Casio 6) In GraarageBand Open New Project, Start by using Piano, Select Keyboard (command K) in the Window menu 7) You should see the keyboard being played on the screen.
PS: Thank you Francois Ferland.

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.

Hello - I am too a personal owner of a CASIO CTK keyboard, a little older than yours (model CTK-601) a great keyboard BTW, and I have connected it to my computer successfuly.

There are 2 ways of connecting the keyboard to your PC......Using the MIDI outputs and a special MIDI to gameport adapter - if you have a very old system and have a joystick port (D-sub shape) on your soundcard or PC, then you use that cable. Of course this is legacy and stopped existing in newer computers, now USB is used.

Only the professional line of soundcards have direct MIDI inputs. For most of us, with consumer soundcards and PCs, there are no MIDI inputs.

The good news is that newer keyboards support USB MIDI and features direct USB connection - so all you have to do is install the drivers that are provided with your keyboard, usually a CD, and follow the instruction to install the USB drivers for your casio keyboard, BEFORE you plug in the cable (very important!) once installed you reboot and connect your keyboard using a USB cable

Now if your keyboard is older and has MIDI outputs, like mine for example, you will need to purchase a MIDI to USB adapter, those have MIDI cables in one end that plug to your keyboard and the other end a USB connector....... I don't know about the rules if I am allowed to post websites, but the product i'm using is the Uno from M-Audio - in google do this search:

"m-audio"uno

(exactly as shown above with quotes, and uno outside quotes)

Your CTK-810 may alreayd have a USB connector on it, as it is a newer generation keyboard - I am pretty sure it does - what you will have to do as stated above is located your bundled CD-ROM and install the USB drivers - you will need to purchase a USB cable (seperately).
