I have a Casio CPS-50 keyboard.It is old but works well. My new computer does not have an MP401 driver so I am unable to use the thousands of midi files available on the net. Regards Neil Tyler

Like your Yamaha midi needs drivers.
https://www.solvusoft.com/en/update/drivers/music-keyboard/casio/privia/px-120/model-numbers/

PX 410r uses IDES 4.0 downloadable from
http://www.casio-europe.com/euro/emi/specials/ides/downloads/
and not another version.

I suggest you uninstall the Casio USB driver from Control Panel'system'device manager then Reboot the PC without the USB cable.
Download latest USB driver from :-
http://support.casio.com/en/support/download.php?cid=008&pid=20
64 or 32 bits versions are both available.
Load driver first. Plug in the usb cable only when software tells you to do so.
Uninstall Data manager if wrong version.
Install IDES 4.0

Your keyboard only has a USB port.
You need to buy a std USB printer cable (A-B).
Download the drivers from Casio.com
Instal the driver first and connect the cable when asked to.
Once connected, the PC will have software MIDI-IN and MIDI-out for your LK94TV

I have the same keyboard and it works...i had trouble installing the drivers cz it doesnt have autorun....what i did was plugged in my usb cable then when the bubble pops up saying found new hardware click onit and follow those prompts instead of opening the cd...once thats installed go to options/midi and you will see the keyboard there as midi be sure to click enable... remember that smc converter is not the installation fo the midi drivers so once u install smc convert your keyboard still wouldnt function as a midi hope that answers your question...

Casio Chord is internal to the keyboard and doesn't come out on MIDI. Transpose is similar and while the button may send a MIDI transpose type signal out, the notes will not transpose in your computer...

use the audio output to send the keyboards internal patch sounds, or use a usb midi adapter to use the keyboard to trigger the garageband midi sounds, if the keyboard has a midi output, that is. the usb output requires software drivers to use, and IS NOT mac compatible. You may have to select a midi source in garage band preferences or settings if you are using midi.

You haven't said whether or not you are using a demo ,version of FL. If you purchased they have Lifetime Free Updates here:http://flstudio.image-line.com/documents/lifetimefreeupdates.html If you didn't purchase, try downloading the newest demo version here:http://flstudio.image-line.com/documents/download.html Some features of demo programs become disabled after a certain time period. I don't know if midi device recognition is one of them for this program. Try hooking your keyboard up first, making sure that you have the correct drivers for the keyboard, your USB adapter etc. Then start FL and see if the program lists your keyboard in the midi device list.

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.

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).

Try downloading MidiOx and troubleshooting with it. It will show you if you have any midi activity and which channel your Casio is transmitting on etc.
