I just got a used Casio WK1250 76 key keyboard. I believe it has a lot more capabilities than I am aware of. I'm looking for a manual to read what all the buttons are for and how to use this fantastic musical instrument.
SOURCE: Casio ctk-496 claims to be midi keyboard controller
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.

Have you tried signing on to your computer as the administrator? I looked at the support pages at Casio and saw how confusing they are. Look at page: http://support.casio.com/information.php?rgn=5&cid=008&pid=114 and page: http://support.casio.com/information.php?rgn=5&cid=009&pid=115. Pay attention to the red lettering. The computer might be considered as the midi out device and the keyboard as the midi in device or the other way around, I'm not sure. Pretend its a telephone conversation with one person talking and the other person replying. I don't know if this helps but you can also try tech support at Sweetwater Sound (800)222-4700.
SOURCE: I fixed the dead keys on my Casio WK-200 keyboard. Now some...
Most of these have VELOCITY sensing and that involves two contacts per note. If the velocity sense on those notes is somehow not working, broken wire or trace on the board or short that MIGHT cause your problem.
SOURCE: My WK- 3700 Casio keyboard is malfunctioning.
One portion of the key scanning matrix has gone bad. First thing is to clean the contacts with 99% isoprophyl alcohol. These USUALLY consist of traces on a circuit board that conductive rubber "pills" under silicone rubber domes are pressed down. Each note usually has two contacts, one closes before the other. This creates "velocity" measurement for the key. IF ONE of the contacts for a key doesn't work, the velocity can detect that the note has actuated, but no release occurs.
This would be on the "STROBE" line for either the first or second contact for THE OCTAVE you have problem with. There are disconnect diodes that prevent sneak paths.
You could have one bad diode, a crack in the circuit board, or a bad connection to the keyswitch board.
SOURCE: How do you replace the adaptor jack on a Casio
Unfortunately the adapter jacks are a bit of a weak point on many keyboards but it is quite seldom the jack socket itself that is at fault.
Often the sockets are soldered directly on to the printed circuit board and are prone to either one of the soldered legs breaking, or even the circuit board itself cracking around the jack socket.
Whilst it is generally possible, with care, to resolder a broken leg on the socket if the actual circuit board has cracked the whole board will have to be replaced.
If the actual jack socket itself is damaged it should be possible to snip through the legs and remove it before soldering a new one on to the stumps of the old legs. this is likely to prove easier than trying to solder directly onto the circuit board, unless this is something that you are experienced at doing.
Apparently you can purchase a full service manual for the Casio WK-1200 here for a modest price but I have not used this source myself so cannot vouch for how good it might be.http://www.tradebit.com/filedetail.php/2084335-repair-manual-casio-wk-1200-electronic-keyboard
