Is there any way to connect my casio ctk1100 to a laptop??

Like your Yamaha midi needs drivers.

Yes. But it depends which connectors you have on your laptop. If you have a small (3.5mm) stereo jack input, then you need one cable with a small stereo 3.5mm jack on one side and a big stereo 6,3mm jack on the other side. (Take a look at the picture below).
Then you plug in side with a small stereo jack in your laptop "line in" input and other side of the cable with a big stereo jack to your Casio CTK-1100 Phones/Output plug on a keyboards rear side...

Be sure to adjust the volume on both the Casio (output volume) and laptop (input volume)...

Cheers!

yes but your have to buy the disk. from pro tool to make it work. you cannot use the simple protool be cause it give you 15 day to use it and than it will expire. and plus your not going to get all of the conponet from try verison.

Casio don't supply PX330 drivers for IPAD.
Get a Windows 8.1 tablet or connect PX330 to a desktop PC and use IPAD to Remote control that PC.

No. Get a more expensive model with USB port built in

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

Yeah, had that problem too with Vista (I used a 64bit) but it should work in Vista (32 bit) with limitations and Windows 7 32 bit

for Vista

for 7

When you are using midi the sounds from your keyboard aren't sent anywhere. What happens is control messages are sent over the midi cable from midi out to midi in on the other device which must have midi sounds on it (in your case the sound card) to make any sounds. The messages can be things like note on/of or pitch bend etc. If you want to send messages to produce a result on your laptop and still here something you can loop the messages by running from midi out on the device end ( your laptop) back to midi in on your keyboard. A much better explanation is available here:http://www.indiana.edu/~emusic/etext/MIDI/chapter3_MIDI.shtml I also signed up to this site (its free) that has great people and lots of info:http://www.recordingreview.com/ I recommend downloading Killer Home Recording setting up which at this time is also free and has the best advice you could want in it. I'd also recommend checking out Reaper which is comparable to Reason, Cubase or Protools. If this helps please let me know.

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 take it You meant LK-210
