Is there a free option to fruity loops?

Unfortunately your model of Casio only has midi in and not midi out. You will be able to use it as an external sound module but not to input notes into Fruity Loops. In other words midi out of your computer to midi in of the Casio with the proper settings will play your Fruity Loops sequences through the Casio.

Fruity Loops version 4 requires Windows up to version XP.

If you happen to have Vista on your PC, you should probably retrofit to XP as there are MANY compatibility problems with Vista and a lot of the special purpose software.

First thing is to COMPARE the PC requirements against what Fruity Loops says it requires.

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.

You can use this keyboard via MIDI to send note on/off information to FriutyLoops. Use for control functions will be somewhat limited to voice change, velocity, and aftertouch.
