Get Kmidimon.  Then you can see the messages your Casio is sending.
Your Casio might send a bulk tuning dump like like how Scala works, or 
it might send a per note tuning message, you might have to configure 
the Casio to send these messages.

If you want to experiment with different tunings try Scala.  The Casio 
might overwrite the Scala tuning, yet another reason to figure it's MIDI 
messages.  An alternate and tedious method to do alternate tunings in 
a sequencer is to included a pitch-bend midi event with every note.

MIDI pitch-bend and alternate tunings have been part of the MIDI 
specification since V1.  The MIDI implementation table for your device 
should tell you if it does pitch bends and alternate tunings.
