Casio PX 310 with GarageBand ...
Thanks for your reply.
I've been onto Casio Support and they say:-
"First, confirm that your computer is equipped with a Sound Blaster or compatible audio card with a joystick port (Dsub 15-pin). If yes, you need a commercially available Sound Blaster MIDI cable adapter.
If your computer does not have a joystick port, you can connect your CASIO keyboard using a commercially available USB MIDI interface. Note, however, that some computers do not support use of a MIDI interface. Be sure to check whether your computer supports use of a MIDI interface before actually purchasing one.
You cannot use the "Analog audio in" socket on your Mac Power Book."
I must confess to being ignorant of GB and its use ... I've had Mac computers for years but have never used that function. I'm essentially an acoustic piano player, but have the Casio in the spare room and use it in the evenings when it would be inconsiderate to play straight piano.
You ask if I want to use the Casio as a controller. At the Apple Store they have a small keyboard next to iMac which they have to demonstrate GB. I guess this would be the controller.
I presume that the "MIDI interface" to which they refer is a black box which would go between the Casio and the GB on my Mac Power Book/
Any pointers would be appreciated ... apologies for my ignorance, but having both the keyboard and GarageBand, I'm curious to know how they might work together.
