This Digital Keyboard does not come with a pedal unit. • You can use the PEDAL1 jack to connect an optional (SP-3, SP-20) sustain pedal. You can use the.

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)...

Generally, all Casio sustain pedals are compatible with all their keyboards, but i normally recomend the SP-20. SP 20 Pedals Products CASIO

They are all compatible. Make sure the port on the keyboard is the same size as the plug on the pedal, usually a phono plug. Also make sure it is a sustain pedal and not an "on off " switch.

if you don't want to wait, you can go to radio shack and get a universal adapter for a bit more, but it should work no problem.

A lot of stuff is not compatible with Vista. Probably best to upgrade it to WIn7.

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 you have set the powerchord/MIDI to the MIDI mode.

You can use FL studio it's easy to adjust and easy to work with. Also you can find more help then maybe any other software out there. Also you can find instructions on Youtube how to hook it up. Cake walk is another one, I think adobe audition can too use to be Cool Edit. You can try pro-tools but it's difficult, at least for me it was and finally Sony Acid does it too. Well good luck.
